In this study, the lateral resistances of mass timber shear walls were investigated for seismic design. The lateral resistances were predicted by kinematic models with mechanical properties of connectors, and compared with experimental data. Four out of 7 shear wall specimens consisted of a single Ply-lam panel and withdrawal-type connectors. Three out of 7 shear wall specimens consisted of two panels made by dividing a single panel in half. The divided panels were connected by 2 or 4 connectors like a single panel before being divided. The applied vertical load was 0, 24, or 120 kN, and the number of connectors for connecting the Ply-lam wall-to-floor was 2 or 4. As a result, the tested data were 6.3 to 52.7% higher than the predicted value by kinematic models, and it means that the lateral resistance can be designed by the behavior of the connector, and the prediction will be safe. The effects of wall-to-wall connectors, wall-to-floor connectors and vertical loads on the shear wall were analyzed with the experimental data.

通过抽拉式连接器连接的大体积木材剪力墙的侧向阻力

在这项研究中,对大体积木材剪力墙的侧向阻力进行了抗震设计。通过具有连接器机械性能的运动学模型预测了横向阻力,并与实验数据进行了比较。7个剪力墙样本中有4个由单个Ply-lam面板和抽拉式连接器组成。7个剪力墙样本中有3个由两个面板组成,这两个面板是通过将一个面板分成两半而制成的。分割后的面板像单个面板一样通过2或4个连接器连接。施加的垂直载荷为0、24或120 kN,用于将Ply-lam墙-地板连接的连接器的数量为2或4。结果,测试数据比预期的高6.3%至52.7%。运动学模型的价值,这意味着可以通过连接器的行为来设计侧向阻力,并且预测将是安全的。利用实验数据分析了墙到墙连接器,墙到楼连接器和垂直荷载对剪力墙的影响。
