BACKGROUND


Bridge
decks
typically extend

past the
fascia

girders, thereby resulting in
a bridge deck

overhang.

Bridge deck o
verhang construction often leads to torsional load
s

on the
girder system that can lead to problems in girder bridges during construction, especially
when the finishing machine rail is placed on the cantilevered portion of the form work.
The main issue is excessive lateral rotation in the fascia girder, wh
ich can cause
potential problems of construction safety
,

maintenance,
thin bridge decks, potential
girder

overstress,
permanent deformation
s,

and rideability issues
.

Field problems have
been reported in Illinois where the fascia girders experienced excess
ive rotation during
construction.


IDOT currently
requires

a system that uses
transverse
tie bars and timber blocks to
brace the steel girders for torsion
,

and requires additional bracing on shallow W27
girders and smaller
.

These systems
, along with the
materials
,

devices
,

and
workmanship
used to implement these s
ystems,

have
performed
inadequately

on many

structures

across the state
.


Poor practices
such as

loose bars, bent bars, tack welded
attachments to shear studs, lapped bars poorly welded together,

inadequate tensioning
of threaded rods,

tie bars spaced greater than specified
,
and substitutions such as
cables, pine 2x4’s, bent brackets, etc
.

contribute to the performance

problems
.


Additionally,

Illinois
permits

contractors
to
provide

alternate bracing systems designed
and detailed by a structural engineer. These systems look good on paper

but often they
do not work

as intended because

the connection assumptions and details are usually
not
properly
achieved
.


A freeware program develo
ped by
the University of Kansas and
Kansas Department of Transportation entitled “Torsional Analysis of
E
xterior Girder”
(TAEG) is typically the go
-
to source which
engineers

use to develop
or

check alternate
bracing systems.


OBJECTIVE


The objective of
this study is to
develop improved exterior girder
bracing system
design
standards
and
policy

utilizing

hardware that
is
either
already commercially available

or
can be developed
and readily provided by the industry.


This research will investigate
the syst
ems that have been
commonly
used by IDOT

to
determine

their effectiveness
,
and develop and investigate improved alternate systems for potential use
.

The
research should evaluate the effects of placing finishing machine loads on the overhang
forms in compa
rison to placement on the exterior girders.

The research

will also identify
specific scenarios (
e.g.
,

beam depth
-
to
-
cantilever ratio,
cross
-
frame/diaphragm spacing,
finishing machine rail locations,
etc.) where additional bracing will not be necessary to
prevent
girder

rotation. Finally, the research
should evaluate the TAEG program and

identify the proper way to model

and analyze IDOT bracing system details

using
the
TAEG program
.



RESEARCH TASKS A
ND
REQUIRED
DELIVERABLES

The researcher shall do a literature search of exterior girder bracing details
, finishing
machine rail locations,

and
related bridge deck construction
policies of other states

to
identify alternate design details, policies, and bes
t practices
.
The research
shall also
include finite elements analyses
,

experimental tests, and field monitoring for both
concrete and steel girder bridges.

Based on the validated models, detailed parametric
studies
shall
be
performed

to investigate the s
ystems
commonly
used by IDOT

to
prevent exterior girder rotation
.

Results from the parametric studies
shall
also

be used
to identify the geometries of girder systems that are prone to problems with the
overhangs
,

as well as to provide design suggestions.



This
research
shall
provide IDOT with
the following deliverables:




Specific r
e
c
ommendations
concerning existing systems/ techniques for
preventing exterior
girder
rotation
for overhang construction to
ensure
that
torsion

is resisted
and
girder rotation

is limited
.


-

-




Specific recommendations for improved standardized overhang construction and
temporary work to resist
torsional loading during construction
.




S
uggest
ions for

specific scenarios (
e.g.,

beam depth
-
to
-
cantilever ratio,
cross
-
frame/diaphragm spacing,
finishing machine rail locations,
etc.) where additional
bracing will not be necessary to prevent beam rotation.




Recommendations for the proper use of the TAEG system for the new IDOT
exterior girder bracing system.


The res
earch should e
nhance the
constructability,
serviceability
, and quality

of Illinois
bridges
,

thereby

reduc
ing

maintenance cost
s for

the state of Illinois.
