Description

The optimaization of a frame structure subject to a elasto-plastic deformation is presented until the building comes to a collapse in order to ensure the safety of the building for the large earthquake. In this paper, Two the mathematical programming method is based on total volume and ultimate strength of a frame structure. We investigate the validity of these optimized design variables and collapse mode by numerical examples with two formulations that replaced constraint with objective function.
