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%。
The anti-seismic performance of the typical wall-to-wall building in Dongting Lake area was studied through field measurement and numerical simulation. The results show that the numerical model can well reflect the dynamic characteristics of the actual structure. The results of time history analysis show that the typical wall construction in Dongting Lake can meet the earthquake resistance requirement of 7 degree (0.10 g) earthquake of our country in ensuring the material strength, and the building of flexible wall roof is more Can basically reach 7 degrees (0.15g) in case of earthquake fortification requirements; flexible building roof wall construction of anti-seismic load-bearing capacity than the semi-rigid roof wall construction of the wall is 23.1% higher; Increasing Seismic Shear Capacity of Semi-Rigid Building with Hollow Walls by 5%.
