摘要:
利用ABAQUS对歪闪斗栱模型进行竖向单调加载数值模拟，研究歪闪斗栱的竖向受力性能，及不同歪闪角度对斗栱的荷载-位移曲线、破坏形态和受力性能等的影响．研究结果表明：在竖向荷载作用下，歪闪斗栱的破坏形态与完好斗栱类似，为栌斗压溃破坏，且歪闪斗栱的破坏更加严重；荷载-位移曲线可用双折线模型表示；当歪闪角度为0°~6°时，斗栱的刚度及允许承载力随歪闪角度的增大而降低，最大降幅为30%左右．研究木结构古建筑歪闪斗栱的受力性能，对修缮、保护古代建筑具有深远意义．
Abstract:
By simulating the skewed Dou-Gong under the vertical monotonic loading based on ABAQUS program, the vertically mechanical behavior of skewed Dou-Gong, the effects on load-displacement curves are failure modes and mechanical performance of Dou-Gong under different skew angle were studied. The results show that the failure mode of skewed Dou-Gong belongs to the crushing collapse of Lu-dou, similar to intact ones under vertical load. Meanwhile, the skewed Dou-Gong is destroyed more seriously. The load-displacement curves can be described by the double broken line model. The stiffness and allowed bearing capacity decrease when skew angle ranged from 0° to 6° increases and the largest drop is about 30%. It is meaningful for repairing and protecting ancient buildings by researching the mechanical performance of the skewed Dou-Gong in ancient timber buildings
