Abstract | [Abstract]: This paper investigates the effects of continuum design domains on the layouts and performance of optimal bracing systems for multistory steel building frameworks under lateral loads using the performance-based optimization (PBO) technique. In the present method, an unbraced steel framework is initially designed for strength using standard steel sections from databases. A continuum structure is then structurally added to the framework to stiffen the framework. Based on system performance criteria, underutilized finite elements are gradually removed from the continuum design domain to obtain optimal bracing systems for the steel framework. The PBO technique is employed to generate optimal bracing systems for 12-story steel building frameworks braced with different continuum design domains under multiple lateral loads. The performance of optimal bracing systems produced is evaluated using a performance index. |
