Finite Element Simulation of Steel Structures
These researchers are using MSI resources for two projects. In both, they use the finite element (FE) analysis software ABAQUS to study the behavior of steel structures. The objective for both is to examine the seismic performance of steel building structures.
Large-scale specimens will be tested at the Multi-Axial Subassemblage Testing (MAST) facility operated by the civil engineering department to produce critical information to improve the design of seismic-resistant frames. Using the unique MAST system, the test will subject the specimen in bidirectional loading, in order to clarify behavioral aspects of seismic building structures. In preparation of the tests planned for mid-to-late 2009 for the first project, and for 2011 for the second project, nonlinear behavior of the test specimen has been simulated by FE analysis. The analysis will also complement findings from the tests.
