Modelling Post-and-Beam Wooden Buildings under Seismic Loads
This paper presents a nonlinear finite element structural model — "PB3D" to simulate the seismic response of Japanese post and beam (P&B) wooden buildings. A versatile mechanics-based "pseudo nail" wall model is used to represent the nonlinear load-drift characteristics of the shear walls under lateral loads. The roof/floor diaphragms are modeled as structural frames with equivalent diagonal bracings to consider the influence of the roof/floor in-plane stiffness on the lateral force distribution among the walls. This approach significantly reduced the overall system degrees-of-freedom while allow the model to represent the key characteristics of the system under lateral loads. Experimental studies on shear walls and floor diaphragm were conducted to calibrate the wall models and the equivalent floor diaphragms. The model prediction agrees well with the shake table test results of a single-storey P&B building. The "PB3D" model provides an efficient tool to evaluate the seismic performance of general Japanese P&B wooden buildings.
