ABSTRACT

This paper is devoted to the investigation into the lateral performance of cross-laminated timber (CLT) shear walls with different construction methods (i.e., platform construction and balloon construction). Quasi-static cyclic tests were conducted on four CLT shear wall specimens. The hysteretic performance, failure modes and contribution of deformability components of the specimens were obtained and compared. Furthermore, analytical prediction models were developed for the CLT shear walls with either platform or balloon construction method. The proposed models were validated by test results and can serve as convenient tools for estimating the lateral load resisting performance of CLT shear walls.

摘要

本文致力于研究采用不同施工方法（即平台施工和气球施工）的交叉层压木材（CLT）剪力墙的横向性能。对四个 CLT 剪力墙试件进行了准静态循环试验。获得并比较了试件的滞回性能、失效模式和变形分量的贡献。此外，使用平台或气球施工方法为 CLT 剪力墙开发了分析预测模型。所提出的模型得到了试验结果的验证，可以作为估计CLT剪力墙抗侧向荷载性能的便捷工具。
