【摘要】 改进了铅芯叠层钢板橡胶垫隔震装置的 Park 模型,提出其双向弹塑性恢复力模型。建议的模型克服了 Park 模型不能从橡胶垫力学试验曲线上直观获取所需参数的缺点。采用本文建议模型的结构分析程序 HBTA2.0可以方便地用于实际隔震结构的弹塑性动力分析,计算结果也更为合理。更多还原

【Abstract】 The elasto-plastic biaxial hysteretic model for elastomefic bearing is proposed in this paper to improve the Park model.The requisite parameters of the proposed model can be acquired directly from the test curves of the elastomeric bearing,which is impossible for the Park model.With the proposed model,the program HBTA2.0 for elasto-plastic dynamic analysis of structures can be applied to real base-isolated structures expediently and its calcu- lating results are more reasonable.更多还原
