- Abstract
- Today’s companies are using three dimensional finite element programs to evaluate
structures of different kinds to a much greater extent than before, among them bridge
structures. These programs can be divided into two groups: general and specialized
programs. The general programs are general in the sense that they don’t focus on a
specific type of structure and allow the user to model most structures. The work with
such programs is often both complex and time consuming. Specialized programs are
designed for the modeling and analysis of a specific type of structure. This results in a
time efficient modeling with a minimum of input.
The aim of this thesis is to develop a methodology for merging the advantages from

such programs is often both complex and time consuming. Specialized programs are
designed for the modeling and analysis of a specific type of structure. This results in a
time efficient modeling with a minimum of input.
The aim of this thesis is to develop a methodology for merging the advantages from
both the program types. This will allow the user to create a bridge model through
parameterization but the model should be created in such way that it is modifiable using
the tools given in general programs.
The methodology is then verified by an implementation into a general program with a
script. This script creates a bridge model with both super- and substructure which can
vary in many different ways. The substructure is limited to columns, abutments, end
shields and wing walls. In addition to the geometric modeling the project also includes
the modeling of the following loads: earth pressure, overload, surcharge, dead weight,
shrinkage, temperature and support displacement. Sets and surfaces are also predefined
by the methodology to make it easier for the user to make changes to the created
model. (Less)
