Name:

Two-span girder simply-supported for DL and continuous for LL

Description:

Modeling demonstration for a two-span girder which is simply-supported for DL and continuous for LL.

Program:

SAP2000

Version:

12.0.1

Model ID:

130


To simulate a two-span structure which is simply supported under dead load, and continuous under live load, a staged-construction load case is defined with five stages, outlined as follows:

  • Stage 1: Add two frame objects, one for each span.
  • Stage 3: Apply load to the structure. Response will be as though the system is simply supported.
  • Stage 4: Fix the moment end releases which are applied in Stage 2.
  • Stage 5: Apply additional load to the structure. Response will now be as though the system is continuous.


Structural response is presented in Figure 1:
