| 摘要: |
| 为研究国产钉连接轻型木结构剪力墙的抗侧力性能,对7组14片不同尺寸规格和构造的剪力墙进行了标准推力试验,并利用ABAQUS建立了剪力墙的有限元模型,对其工作性能进行分析.结果表明:钉连接失效是导致剪力墙破坏的主要原因;剪力墙的承载力和刚度与墙体宽度成正比;开洞剪力墙的承载性能均比宽度与洞口两侧墙肢总宽度相等的剪力墙高;石膏板对剪力墙的承载性能有显著提高作用.由试验和有限元分析结果拟合得到了预测剪力墙的荷载-位移曲线、极限承载力和刚度的经验公式. |

| Abstract: |
| In order to investigate the performance of shearwalls connected with domestic nails in light wood frame structures,lateral resistance tests were conducted on 14 shearwalls in 7 groups with different dimensions and structural arrangements.Using ABAQUS,FE models of shearwalls were developed to simulate the structural behaviour.Both the experimental and numerical results show that failure of nail connections is the primary cause leading to the failure of shearwalls.The load-carrying capacity and the stiffness of shearwalls are proportional to the width.The performance of shearwalls with an opening,in terms of load-carrying capacity and stiffness,is higher than that of shearwalls without an opening but with the width equaling to the sum of the wall segments from the two sides of the opening.Gypsum panels improve the performance of shearwalls significantly.The empirical equations to predict the lateral resistance and stiffness of shearwalls were derived based on the test and FE modelling. |
