摘要
利用ANSYS对工字梁与H型钢柱腹板连接节点进行有限元分析,建立梁翼缘连接板剪切变形和梁连接板部分弯曲变形理论分析模型,推导出梁翼缘连接板剪切变形的等效刚度公式,根据楔形梁段假定推导出梁连接板部分的抗弯刚度公式,并通过有限元分析确定刚度系数。根据对梁柱腹板连接节点各部分刚度和强度分析,建立腹板连接节点模型。这个简化模型可以用来分析单向荷载和循环荷载作用下梁柱腹板连接节点的响应。
Finite element analyses of web connections between H-shaped columns and I-section beams were performed using the ANSYS program Based on finite element analyses, theoretical analyzing models are developed respectively for shear deformation and flexural deformation of beam-flange plate. The equivalent shear stiffness equation of beam-flange plate is derived. The flexural stiffness equation of beam-flange plate is established under the assumption of beam with tapered-flange. A simplified model is developed to describe the monotonic and cyclic loading behavior of beam-to-columns web connection in steel moment-resisting frames. Reasonable agreement between model predictions and finite element analysis results is achieved. With this simplified model the behavior of the web connection subjected to monotonic and cyclic loading can be easily obtained.
