Abstract: The Chinese code for seismic design of buildings (GB50011-2010) allows the use of sets of ground motions in the seismic design and analysis process. However, the prescriptions for record selection are somewhat vague compared ...

Abstract: In this paper, an improved particle swarm optimization (IPSO) method, which is based on standard particle swarm optimization (PSO) and a changing range genetic algorithm (GA), is proposed, and it is applied in the form-finding ...

Abstract: Piston theory is widely used in modeling unsteady aerodynamic force caused by surface vibration. The nonlinearity of piston theory is determined by its high-order terms, which are significantly influenced by different ...
