摘要:
为研究歪闪斗栱的抗震性能以及不同歪闪程度对斗栱的滞回性能、承载力、刚度、耗能等性能的影响,以θ角度切削平板枋的方式来考虑斗栱的不同歪闪情况,并利用ABAQUS程序对歪闪斗栱进行了水平向循环加载数值模拟。研究表明:在水平向循环力的作用下歪闪斗栱产生整体滑移,馒头榫发生剪切破坏;滞回曲线呈现正反向加载不对称现象,歪闪角度越大,不对称现象越显著;侧向刚度及能量耗散系数随角度的增大而逐渐减小,但仍具有较好的变形能力和耗能能力。揭示了斗栱的歪闪程度对其抗震性能的影响,研究结果可为现存木结构的残损评估与修缮加固提供参考。
Abstract:
In order to find out the seismic behavior of skewed Dou-Gong and the effects on Dou-Gong hysteretic behaviors, bearing capacity, stiffness, energy dissipation and other properties under different skew angle,Dou-Gong skew level were considered by the method of cutting PingBanFang in theta angle, and the skewed Dou-Gong were simulated under cyclic lateral loading based on ABAQUS program. The results show that,the skewed Dou-Gong produces the overall slippage and the dowel produces shear failure under cyclic lateral loading. The hysteretic curves are asymmetrical and the asymmetry is more obvious when the skew angle increases. The stiffness and energy dissipation coefficient decrease with the increase of damage degree, but the skewed Dou-Gong still has a good ability of deformation and energy dissipation. That the skew angle impacts on Dou-Gong seismic behavior is explored in this study, and the result of test provides a reference for the existing wood structure damage assessment and repair of reinforcement.
