摘要:
设计8种不同种类节点板的模型,考虑几何非线性和材料非线性,对模型的偏心加载平面外稳定承载力进行有限元分析,研究不同构造形式对于节点连接部位承载能力的影响因素.研究结果表明,影响节点平面外刚度和承载能力的因素中,螺栓的布置是最重要的关键因素之一.螺栓布置要尽可能使节点板的塑性铰线沿着面内最长的路径扩展开,才能充分发挥节点板的承载能力.此外,节点板平面尺寸宜设计小些,尺寸大的板反而会减小面外承载力; 节点板的加劲肋会影响节点板的应力分布和塑性扩散.
Abstract:
Eight different types of joint plate models are designed.Considering both geometry nonlinearity and material nonlinearity,the out-plane stability bearing capacity of models loaded with eccentricity are analyzed by finite element method,to study the effect of different construction forms on the bearing capacity of joint plates.The research results show that the bolt distribution is one of the crucial factors which affect the out-plane stiffness and load bearing capacity of joint.Bolts should be distributed to make the plastic hinge line extend along the longest path in plane,so the load bearing capacity of joint plates could be exerted fully.Moreover,the plane size of joint plates would be small,since the load bearing capacity of joint plates descends with increasing plate size.The stiffener of joint plates influences the stress distribution and plastic spread of joint plates.
