A structure
The Design Process
Controlling Design Specification
After a site has been selected and the main logistical constraints established, typical steps in the structural engineering design process are as follows:

List of Long Bridge Span for Each Type
Determination of the external loads
For the design of a bridge such as the one in our example, the following loads will need to be considered:
Selection of the limit states or performance criteria
Creation of an analytical model
The model has to have some physical attributes (member sizes, strength of the materials, etc.) before we can proceed to the next step. In addition, the following remarks are in order:
Computations of stresses and strains
Evaluation of results
Design of members to satisfy (5).
Reanalysis to ensure adequacy of the final design.
