| 摘 要： | 通过现场实测及数值模拟对洞庭湖区典型空斗墙建筑的抗震性能进行了研究。研究结果表明:数值模型能很好地反映实际结构的动力特性。时程分析结果表明,在保证材料强度的情况下,洞庭湖区典型空斗墙建筑可满足我国抗震规范7度(0.10g)多遇地震的设防要求,其中柔性楼屋盖空斗墙建筑更是可基本达到7度(0.15g)多遇地震设防要求;柔性楼屋盖空斗墙建筑的抗震抗剪承载力比半刚性楼屋盖空斗墙建筑的要高23.1%;眠砌构造柱可提高半刚性楼屋盖空斗墙建筑抗震抗剪承载力5%。

| Abstract: | In this paper,the seismic performance of typical rowlock wall building in Dongting Lake area was studied by field test and numerical simulations.The results show that the dynamic characteristics of numerical model are well agreeable with those of the actual structure,so the results of numerical simulations can reflect really the seismic performance of actual structure.The seismic performance of typical rowlock wall building in Dongting Lake area can satisfy with the demand of seismic fortification intensity... |
