DIN Technical Reports
101-104 for Bridge Construction
The DIN technical reports
101 to 104 introduced on 1 May 2003 are binding for the areas of
federal highways, federal waterways and the federal railroad (Bahn
AG).
The Bridge Check
According to DIN Technical Report module of the InfoCAD
program system implements DIN technical report 101 (Actions) and DIN
technical report 102 (Concrete Bridges).
The module is used to conduct checks for any beam or shell
structure. Elements with no prestress as well as prestressed
elements with subsequent bond, without bond, with external
prestressing and in mixed construction can be analyzed.
- Consideration of any stresses and loading
- Special preparation of the load module LM 1
- Automatic combination of the actions according to DIN
technical report 101
- Construction and final states for all
action combinations
- Optionally user-defined actions
- Checks at the ultimate limit state DIN technical report 102
- Minimum reinforcement for ensuring robustness
- Bending
with or without longitudinal force or longitudinal force alone
- Lateral force under consideration of the minimum level of
reinforcement
- Pure torsion and torsion with lateral force
- Check against fatigue (concrete, bending, shearing and
torsion reinforcement as well as for tendons)
- Checks at the serviceability limit state DIN technical report
102
- Minimum reinforcement for the crack width limitation
- Limiting the crack width through direct calculation
-
Check of the decompression
- Limiting the concrete
compressive stress
- Limiting the reinforcing steel stresses
- Limiting the prestressing steel stresses
- Check of the
inclined main tensile stresses
Example:
A double-girder prestressed T-beam bridge is processed using the
following steps:
- Selection of structure type and check specifications
- Input of load model 1
- Definition of actions
- Design and checks according to DIN technical report 101 und
102 with
- Minimum reinforcement for ensuring
robustness,
- Longitudinal reinforcement at the ultimate
limit state,
- Shear reinforcement at the ultimate limit
state,
under consideration of the minimum level of
reinforcement,
- Minimum reinforcement for the crack width
limit,
- Check of the crack widths using direct calculation,
- Check against fatigue.

The system preparation, input of
the load and guiding of the tendon group follow the normal
procedures and are not explained here in greater detail. First
set the properties regarding the structure and sections:
According to FB 101 and 102, the object under scrutiny is a
'street bridge' made of 'concrete'. |
For the main girders the requirement class 'C' is
set:
Load model 1 clearly describes the placement of the tandem system
and the UDL loads on the bridge. In the model you can define any
number of variations or lane configurations:
The distance between vehicles, the load distribution height and
the centrifugal load of the tandem systems are automatically taken
into consideration.
The load model 1 as well as the other load cases now only need to
be assigned to the corresponding actions. The program then creates
the desired action combinations on its own.
The next step in the program is to combine the actions, design
the system components and conduct the corresponding checks. The
results can be presented graphically and can also be documented in a
detailed log.
Maximum value of the upper and lower longitudinal reinforcement
resulting from robustness, bending with normal force, crack check
and fatigue:
Min./max. steel stresses from fatigue
(stress range):
Utilization of the allowable stress range:
Stresses from the decompression check:
