摘要

摘要: 由冷成型的薄壁钢面和刚性泡沫绝缘蕊子所组成的建筑用夹蕊板条,用来作为多功能建筑隔墙,日益普遍.本文总结了十多年来的研究工作,阐明了包括弯曲应力、挠度、弯曲折皱、轴向稳定、热应力以及振动在内的各种结构性能.研究中,采用了分析法(边界值法)、数值法(有限样条法、有限层法和有限棱柱体法等)以及实验法(全尺寸实物试验),写出了关键方程,并对各法所得结果进行了比较研究.

Abstract: Architectural sandwich panels with thin-walled cold-formed steel facings and rigid foamed insulating core are becoming more and more popular as enclosures for system buildings. In this paper, the structural behavior, including flexural stresses/deflections, flexural wrinkling, axial stability, thermal stresses and vibration, is presented, summarizing more than a decade of research. Methods used are analytical (boundary-valued approaches), numerical (finite-strip, finite-layer, finite prism approaches) and experimental (full-scale testings). Key equations are formulated, and results by different methods are compared.
