摘　　要：利用ANSYS程序对钢柱腹板连接节点进行有限元分析,建立柱腹板连接节点的分析模型,并对其应力分布进行了详细分析。基于弹性理论和屈服线模型建立了薄膜法计算模型,推导出柱腹板在横向荷载作用下承载力的计算公式。Finite element analyses of column webs subjected to loads delivered by plates parallel to the column flanges and centered on the web were performed using he ANSYS program. Based on finite element analyses, analyzing models are developed respectively for column webs. And the stress distribution was analyzed in detail. Based on elastic beam or plate theory, or on plastic plate （yield line）theory, a membrane method have been shown according to non--linear membrane action has been developed. A equation is developed to describe the transversely loaded webs.
