| TAEG 2.0 - CORRECTED
ERRORS AND CHANGES
Discrepencies were detected in the TAEG 2.0 results at
the end of June 2004. These discrepencies were determined to be in need of
fixing and after a detailed investigation of the code, the errors were found.
It was also determined that the errors were significant enough to necessitate
an updated version and re-release of the program. This provided an opportunity
to improve other aspects of the program, as well.
The following is a description of the corrected errors
and other changes to the program:
WHEEL LOAD RESET:
An error was detected with the "Wheel Load" output on the
"Calculated Bracket Forces" form. While conducting several, similar
examples with minor adjustments to the "Bracket Spacing" on the
"Bracket Data" form and the "Wheel Spacing" on the
"Load Data" form, it was apparent that the "Wheel Load"
output was not changing.
Code was added to TAEG 2.1 to reset the "Wheel Load" for each
separate calculation. The problem in TAEG 2.0 was that the "Wheel
Load" output would not change from calculation to calculation if the most
recent calculation produced a result less than any of the previous runs. This
is because code was in place to find the worst case scenario or ultimate wheel
load for a bracket, which is the conservative approach. Therefore, the only way
to ensure getting the correct result was to exit out of the program and restart
TAEG for each separate example. Obviously, this is not ideal. The nature of the
program encourages minor adjustments and tweaking of a bridge's support
systems in order to obtain the most desireable results. Thus, it was necessary
to identify the problem, determine a solution, and test the new code for
WHEEL LOAD CONVERSION
IN U.S. CUSTOMARY UNITS:
Another error detected in TAEG 2.0 also dealt with the "Wheel Load"
output on the "Calculated Bracket Forces" form. While conducting
examples in English or "U.S. Customary" units, it was apparent that
the results were not even close to what they should have been. However, when
the results were converted to Metric or "S.I." units, using the
"Units - Change S.I. to U.S. Customary" option in the main pull
down toolbar, the answers were correct. After investigation of the code, the
cause of the error was found in the unit conversion factors.
All internal calculations within TAEG, regardless of the input units, are
conducted in base units of kilonewtons (kN) and meters (m). Therefore, it is
necessary to convert all input variables and to then convert all output results
back to the desired units. The "Wheel Load" output in "U.S.
Customary" units was determined to be in the form of "Load per Unit
Width" (kips/ft.) rather than just "Load" (kips). Therefore,
to get the correct results, simply multiply the "Wheel Load" output
in "U.S. Customary" units by the conversion factor for meters to
feet or "3.28083989501." Incidentally, the reason the "Wheel
Load" output was correct when the units were converted to
"S.I.", is that there is no internal conversion necessary for
loads; i.e., input load units are kN and output load units are kN.
The other changes made to the program were improvements to make it more user
friendly. Here is a brief list of some of those changes:
- Output is calculated or recalculated whenever units are changed. This
eliminates the error of having output values in one set of units and output
unit labels in another.
- Output is cleared when a file is opened.
- All forms remain shown (unhidden) whenever "New",
"Close", or "Open" is selected.
- The entire input text box value is selected when clicked in or tabbed
to. This improves the editing of values.
- The default units were changed from "S.I." to "U.S.
- The "Independent Units" option was removed.
The status bar at the bottom left corner of the program's window
was changed to show the "Current Units."
- The "Units" menu in the main toolbar was changed. A
"New Project" option in either units was added.
- Units were changed from "psi" to "ksi" for the
following, when "U.S. Customary" units are chosen:
- "Stresses Due to Non-Composite Dead
Load" on the "Load Data" form
- All output on the "Calculated
- "Maximum Stress in the
Diaphragm Due to Torsional Load (M)"on the "Calculated Lateral
Support Response" form
- Trailing zeros were removed from output values and converted input
- The project number input field on the "Project Information"
form was changed from "KDOT Project # :" to read "Project
Number :". This makes the program more universal to all its users.
Our goal was to correct any errors that were found and to make the program
better overall. We hope that we accomplished both goals. We would appreciate
any comments or suggestions for any future releases. The contact person for any
questions or comments regarding TAEG is:

| BOLTED SPLICE UPDATE
For Steel Bridge
Projects that have a letting date after July 1,
2004, all bolted connections will use English
(and bolt holes) only.
All shop drawings for lettings after July 1, 2004 shall specify English bolts
with the corresponding English holes.
Accomplish this on the plans by one of the following methods:
- Specify English bolts and bolt holes on all plans that will be let after July
1, 2004. All splice dimensions shall remain in metric.
- If it is impractical to change bolted details for plans to be let after July 1,
2004, place a note on the General Notes sheet that specifies the use of English
bolts and bolt holes only: "ENGLISH BOLTS: Replace all M24 bolts
as detailed with 7/8" diameter bolts and
replace all M20 bolts with 3/4" diameter
bolts. Shop details will show the English bolts
with the corresponding English bolt-hole diameter." After September, 2004, all details will show English
- For plans let prior to July 1, 2004, bolting details may remain in metric and
continue using the note stating: "Bolted splices have been designed for
USC substitution". If a splice was designed only for metric bolts and the
supply of metric bolts is depleted, the splice will need to be re-designed
using English bolts.
| APPROACH SLAB JOINTS
There are two types of joints allowed in the Bridge Approach Slab: Type B
(Two-Part Silicone) and Type C (Preformed Elastomeric Neoprene) as shown on
KDOT Standard Drawing RD662 SI. The maximum allowable gap width for the Type B
Joint is currently shown as 75 mm. This maximum allowable gap width (for the
Type B Joint only) is being reduced from 75 mm to 40 mm. Therefore, for plans
currently under design, make the necessary change on Standard RD662 SI until it
| DESIGN OF BOLTED
SPLICES DURING THE
TRANSITION FROM METRIC TO ENGLISH
that are surveyed in metric will continue to be
designed, detailed and constructed in metric.
One exception to this policy concerns bolted splices
on steel girder bridges. Since the supply of metric
bolts will eventually be exhausted, English bolts
will have to be used. Therefore, design bolted
splices on metric jobs assuming US Customary bolt
sizes (7/8' bolts for main members; 3/4' bolts
for secondary members). However, detail the bolted
splices assuming metric bolt sizes (M24 bolts
for main members; M20 bolts for secondary members;
spacing; edge distances, etc.).
Place a note on the bolted splice detail sheet immediately above the revision
block. The note shall read as follows: Bolted splices have been designed for
If the supply of metric bolts is exhausted and plans still exist that are
detailed using SI Metric-designed bolted splices, these splices will need to be
checked/redesigned for the substitution of USC for SI Metric bolts. The shop
details must reflect the changes.

| Teflon Bearing Devices
Recess all horizontally installed polytetrafluoroethylene (PTFE) surfaces for
Bearings into its steel substrate by one-half of the PTFE's thickness. Use
a PTFE thickness of 6 mm. This will prevent any excessive creep or plastic flow
of the PTFE from occurring which could lead to separation or bond failure. In
addition, confining the PTFE permits the use of a higher contact stress. The
maximum exposed thickness of 3 mm will also give the longest wear life.
for Pins used in Steel Bearing Devices
For pins used in the construction of steel bearings, specify ASTM A 108 Gr.1018
for pins 100 mm or less in diameter.
For pins greater than 100 mm, Article 6.4.2 of the AASHTO LRFD Bridge Design
Specifications (2nd Ed.), specifies steel forgings as per ASTM A 668M. Steel
forgings are not guaranteed to be weldable, therefore only use the A 668M
specification for pins that are not to be welded.
For pins greater than 100 mm that are to be welded, specify ASTM A 572M Gr. 290
(max 150 mm plates) or Gr. 345 (max 100 mm plates). Two plates can be welded
together in the shop and machined into two half pins. Therefore, two 150 mm
plates can produce two half pins with a maximum diameter of 300 mm. Likewise,
two 100 mm plates can produce two half pins with a maximum diameter of 200 mm.
| Haunched Slab Standards
Beginning with Field Checks in February 2003, all new Haunched Slab Bridges on
the State System will use the standard superstructure design that includes the
Kansas Overload Provision. Consequently, the substructure must also be designed
to include this additional load.
Kansas Department of Transportation Secretary, Deb Miller has decided that
Kansas will go back to the English system of measurement. However, if a project
has been started in metric, it will be completed in metric. The process for
conversion will be set up soon. Details to follow.
| TAEG (Torsional
Analysis of Exterior Girder) Version 2.0
The State Bridge Office (SBO) has released TAEG (Torsional Analysis of Exterior
Girder) V. 2.0 for use in the review of overhang false work for beam\slab or
girder\slab bridge structures during deck placement. This version has expanded
boundary conditions to facilitate skews and discontinuous cross-frames or
diaphragms. The software (design tool) is being distributed on CD and includes
the abstract, final report and a users manual that can be used as a tutorial.
Initially, this CD will be sent to current users (those registered in the SBO
This software is available by request through the KART.
This version, like the previous versions, is not structural analysis software
and therefore will not calculate spatial structural responses due to dead loads
or other non-composite effects. These values are inputted into TAEG 2.0 and the
torsional effects are superimposed to give the total effect.
| NEW REQUIREMENTS
FOR "CONTRACTOR STAKING"
Special Provision 90M - 260 "Contractor Construction Staking" has
been revised (R1). When staking for bridges, the specifications now call for
two independent surveys. In order to alert the Contractors of this change,
place the following note on the "General Notes and Quantities" sheet
immediately under the table of bid items:
** Contractor Construction Staking for bridges requires two independent surveys.
See KDOT Specifications.
(This change is in effect for Projects let in the July, 2002 letting.)

| KDOT POLICY FOR
SHOP DRAWING PROCEDURES
KDOT has developed a document that sets policy for the distribution of shop
drawings. The document's intent is to provide uniformity for handling
shop drawings related to bridges. The document covers both KDOT and
Consultant-designed jobs for main and secondary-system bridges. The new
procedures in this document will eliminate delays, unnecessary paperwork, and
confusion caused by the use of different procedures by designers and
fabricators. KDOT solicited input from the consultant community and from
fabricators when developing this document.
Consultants and fabricators working for KDOT will follow these procedures. Click

| SHEAR STUDS TO BE
APPLIED IN THE SHOP
OSHA has ruled that if fall protection is provided, studs may be shop applied.
When studs are shop applied, the Bridge Office feels we get a better product at
less cost, therefore we will revert to requiring studs be applied in the shop.
Notes and Specifications will be modified to reflect this revised policy. Squad

| Revision to RCB
Program (Wing Details)
It had been brought to the attention ot the Bridge Office that several long
wingwalls on skewed box culverts were cracking shortly after they were
constructed. Sometimes this occurred even before the wingwalls were backfilled.
Cracking was most severe where the wingwall attached to the box.
To help alleviate this problem, the Bridge Office decided to make the wingwalls
on certain skewed boxes freestanding.
It was noted that normal boxes up to 3.05 m high typically did not experience
any distress. The wingwall length on a 3.05 m normal box is 6.25 m. Thus it was
determined to make all wingwalls over 6.5 m in length freestanding.
This effects the following box culverts:

This revision is scheduled to take place on September 12, 2000.
It is not necessary to replace existing affected box details with the new

PROJECT SPECIFICATIONS - CONCRETE
If structural concrete is designated as Class AAA or Class AAA(AE) Concrete on
the plans, furnish concrete as per the Standard Specifications for such. NOTE:
The f'c should be shown as 28 MPa on the plans. If f'c is shown as 30 MPa, the
above still applies.
This includes RCB standards, and US Customary plans designed for f'c = 4 ksi
which have been converted to SI Metric.
If structural concrete is designated as Concrete (Grade 30) or Concrete (Grade
30)(AE) on the plans, furnish concrete as per this Special Provision.
This includes all new designs using f'c = 30 MPa. New designs after 8-29-95 are
to use SI Metric concrete grades. (See SI Procedure Update Memo 95.8.3 8-29-95)
NOTE: The UNIT STRENGTH noted in the lab mix design requirements is intended to
produce a field concrete which meets or exceeds the f'c Grade required about
98% of the time. In other words, the lab mix design is at least two standard
deviations above the f'c Grade requirement.
