弯剪作用下螺栓角部连接的性能分析

研究了腹板角钢尺寸对双腹板顶底角钢的弯曲-转动性能影响。研究中采用了多个三维有限元模型，以其几何和材料特性作为影响参数。在这些模型中，所有的连接组件，如梁、柱、角钢及螺栓都采用实体单元建模。构件间的相互作用效应，如螺栓滑移和摩擦，采用表面接触算法建模。为更精确地评估连接件的性能，在栓杆上施加预拉力作为第一荷载。

Behavior of Bolted Angle Connections Subjected to Combined Shear Force and Moment

In this paper,the effect of web angle dimensions on moment-rotation behavior of bolted top and seat angle connections,with double web angles is studied. Several 3D parametric finite element (FE) models are presented in this study whose geometrical and mechanical properties are used as parameters. In these models,all of the connection components,such as beam,column,angles and bolts are modeled using solid elements. The effect of interactions between components,such as slippage of bolts and frictional forces,...
