| 摘 要： | 等效框架模型兼具了高计算效率与高计算精度的优点,是目前世界上抗震性能评估研究与工程领域使用最广泛的砌体结构建模工具。文中介绍了无筋砌体结构等效框架模型在有限元软件OpenSees中的实现,并以帕维亚大学1、2层、足尺无筋砌体结构原型地震试验为研究对象,对其有效性进行验证。结果表明,计算pushover曲线与试验数据符合较好,文中的等效框架模型能够有效模拟无筋砌体结构的整体地震响应。

| Abstract: | The equivalent frame model combines the advantages of both high computational efficiency and accuracy. It is currently the most worldwide used masonry structure modeling tool in seismic performance assessment research and engineering field. The realization of the equivalent frame model of the unreinforced masonry structure in the finite element software OpenSees is introduced. And the model validity is verified by seismic test of one two-story full-scale unreinforced masonry prototype in the University of Pavia. The results show that the calculated pushover curve is in good agreement with the experimental data. The equivalent frame model of this paper can effectively simulate the overall seismic response of the unreinforced masonry structure. |
