新型木建筑材料——交叉層積木介紹及其連接的試驗研究

Introduction to a new engineered wood-based product-cross laminated timber and experimental study on cross laminated timber bracket connection

  • 摘要: 交叉層積木作為一種新型木建筑材料已經在北美地區推廣開來,然而在我國還沒有得到引進和推廣.本文介紹了這種新型材料的性能特點,總結其生產工藝、設計方法和研究進展,重點對交叉層積木七種半剛性連接的抗震性能進行試驗研究.研究表明:緊固件全部被拔出的失效模式為理想的延性破壞模式,滯回曲線表現出高度非線性、剛度退化、強度退化以及捏攏現象.通過試驗數據分析,給出了在延性和承載能力兩方面最佳的連接.

     

    Abstract: Cross laminated timber(CLT),a new generation of engineered wood-based product,is gaining attention in the North American market,but it has not been introduced and spread in China yet. In the paper,the mechanical properties of CLT are introduced in details,and the production technology,design methods and research progress are summarized as well. What's more,an experimental study on CLT flexible connection in seismic performance is done. The results show that the failure with all fasteners pulled out is disclosed as an ideal ductility failure. Highly nonlinear,stiffness degradation,strength degradation and pinching are illustrated in the hysteresis curves of connection. An excellent connector in ductility and load capacity is presented by test data analysis.
