摘　　要：点支承板件的应用包括螺栓连接受压板件和对拉螺栓拉结的双钢板内填混凝土组合墙。论述了点支承板件受压时板式屈曲和柱式屈曲的临界应力的计算公式,为使弹塑性临界应力达到屈服强度必须限制的螺栓纵向和横向间距。对比了对拉螺栓双钢板组合墙和多腔钢管混凝土组合墙的不同,对组合墙的对拉螺栓提出了设计要求。Plates supported by bolts find application in bolted connections and in composite walls whose two face plated are interconnected by tie bolts and concrete is filled in between.This article presents the formula of the buckling stresses of this type of plate when plate-like and column-like buckling occur respectively.The bolt-bolt distances both in line and in row were determined by requiring their capacity be the yielding strength.The difference between the composite wall with double face-plate and tie-bolts and the multicellular concrete-filled tube wall is discussed and the design requirement on tie-bolts are provided.
