Summary
An innovative methodology for simulating the dynamic response of wood-framed residential buildings in Japan is presented, in this paper, for purposes of seismic performance assessment and retrofitting. The proposed method, which can simulate inelastic behaviour of structures, is capable of showing realistic progressive collapse mechanisms and accurate seismic response of structures. The sequence of analyses and results in the form of computer animations provide real-time assessment of structural integrity and a way to identify the weak points of a structure. Applications to real wood-framed residential buildings in Japan were used to show the effectiveness of the methodology in seismic performance assessment and in retrofitting.
