摘要
开发和评估考虑轴力和双向弯矩相互作用的恢复力模型。首先,基于金属塑性原理,采用C++语言开发轴力-弯矩相互作用恢复力模型(简称N-M模型),并介绍其基本原理。然后,结合一有实测震害记录的框架模型和纤维模型,综合评估N-M模型在预测建筑结构非线性动力时程反应、振型、结构整体极值响应、低周反复荷载作用下响应中的有效性。结果表明,N-M模型预测的结果和实测震害记录吻合良好,具有较高精度,可为结构非线性分析提供合理高效的计算途径。
A tentative development and evaluation has been made of the axial force-bending moment interaction hysteresis model.Based on the principle of metal plasticity,the axial force-bending moment interaction hysteresis model(N-M model)has been developed,with its basic principle introduced.Combined with a frame model and a fiber model,an evaluation has been made of the effectiveness of the N-M model in predicting the structural nonlinear dynamic time history response,mode shape,global extreme value response and the effectiveness of the response under reversed cyclic loading.The results show that the predicted results of the N-M model,characterized with a high accuracy,are in good agreement with the measured earthquake damage records,thus providing a reasonable and efficient calculation way for the nonlinear analysis of structures.
