加载制度对具有 Bouc-Wen 模型特征的结构反应的影响
Effects of Loading Protocol on Structural Response with the Bouc-Wen Model Characteristics
摘要
Abstract
According to the ISO and CUREE cyclic test loading protocol,some mechanical performance parame-ters of wood framed constructions were calculated in Bouc-Wen hysteresis model.Based on analysis of the ultimate strength,ultimate displacement,stiffness,energy dissipation and strength and stiffness degradation of wood framed construction,some basic conclusions on the mechanical performance considering the influence of different loading pro-tocols and reference displacements were obtained.The influence of the loading protocols and reference displacements should be taken into consideration in order to evaluate the mechanical performance parameter based on the test results exactly.Reference displacement equal to 120mm resulted in a 12%~13% and a 66%~68% increasing in ultimate strength and ultimate displacement respectively when compared with reference displacement equal to 60mm under ISO protocol.Reference displacement equal to 100mm resulted in a 4%~6% and a 55%~58% increasing in ultimate strength and ultimate displacement respectively when compared with reference displacement equal to 50mm under CU-REE protocol.The loading protocol appeared to have little influence on the scant stiffness of the wood framed con-struction.It was shown that the ISO protocol with different reference displacements had more effect on the energy dis-sipation and strength and stiffness degradation when compared with the CUREE protocol.关键词
