Topology optimization for buildings in seismic zones within a PBEE framework Bobby, Sarah; Spence, Seymour M. J.; Kareem, Ahsan
This paper presents a probabilistic performance-based topology optimization framework for the conceptual design of uncertain building systems in seismic zones. The stochastic nature of the ground motions is rigorously considered in a simulation-based probabilistic performance assessment framework that allows for the definition of a novel decoupling technique that efficiently separates the probabilistic analysis from the optimization loop. In particular, the methodology is based on the construction of a series of approximate sub-problems with simplified governing equations, which conveniently allows their evaluation using established techniques for static, deterministic topology optimization problems. The applicability and efficiency of the method is demonstrated on a case study.
