摘要:
为研究钢-竹组合框架中连接钢-竹组合柱和钢-竹组合梁的节点性能,通过拟静力试验得到不同参数下半刚性节点的弯矩与转角的多项式拟合关系,在此基础上建立了6榀2层钢-竹组合框架的数值模型,进行了地震作用下的有限元分析,探讨了节点对钢-竹组合结构抗震性能的影响。为充分考虑节点的半刚性特性,采用Combin39非线性弹簧单元模拟节点,研究了6榀框架在不同情况下的最大水平位移与最大基底剪力、水平位移与基底剪力时程曲线和滞回曲线等指标。结果表明:钢-竹组合框架滞回曲线饱满,抗震性能突出,提高节点处螺拴的强度和设置加劲肋对提高钢-竹组合框架的抗震性能有明显效果,节点的构建因素对框架的抗震性能有显著影响。
Abstract:
In order to study the performance of bamboo-steel composite frame joint which connected bamboo-steel composite column and bamboo-steel composite beam, moment and angle polynomial fitting relationship of semi-rigid joints under different parameters were obtained by quasi-static test. Based on this, the numerical models of six pieces of twolayer bamboo-steel composite frame were built, the finite element analysis under seismic action were carried out, and the influence of joints on the seismic performance of bamboo-steel structure were discussed. In order to fully consider the characteristics of semi-rigid joints, Combin39 nonlinear spring element was used to simulate joint, the maximum displacement and base shear force curves, displacement and base shear time history curves and hysteresis curves of six frames under different situations were studied.The results show that the hysteresis curves of bamboo-steel composite frame is plump, the seismic performance is outstanding, improvements of the bolt strength in the joint and the stiffeners set have obvious influences on improvement of the seismic performance of bamboo-steel frame, the build factors of joints have distinct effects on seismic performance of frame.
