摘要

摘要: 正交胶合木（CLT）剪力墙结构建造方式主要有平台施工法和连续施工法两种。为研究建造方式对CLT剪力墙抗侧性能的影响，对平台式和连续式的CLT剪力墙进行往复加载试验，对比了不同建造方式下CLT剪力墙的破坏模式、最大承载力、弹性刚度以及耗能水平。结果表明：在相同的加载位移下，连续式的CLT剪力墙底层连接件的自攻螺钉破坏较平台式CLT剪力墙严重；连续式的CLT剪力墙的整体性和耗能性能较平台式的CLT剪力墙好；两种建造方式的CLT剪力墙的最大承载力主要受底层连接件承载力控制。

Abstract: The most common forms of construction systems in cross-laminated timber (CLT) are platform construction and balloon construction. In order to investigate the effect of construction type on lateral performance of CLT walls, two CLT walls with different construction types (i.e., platform construction and balloon construction) were tested under reversed cyclic loading. Based on the experimental results, the failure mode, peak capacity, elastic stiffness and energy dissipation of the two CLT walls were compared. The results showed that more damage was suffered by the self-tapping screws connected to foundation beam in CLT walls with balloon construction than platform construction. The structural integrity and energy-dissipating capacity of CLT walls with balloon construction were better than those of CLT walls with platform construction. The peak capacity of CLT walls with two construction types were both greatly affected by the performance of connections connected to the foundation beam.
