Structural Behavior of Composite Panels Made of Lightly Profiled Steel Skins and Lightweight Concrete under Concentric and Eccentric Loads
Publication: Journal of Structural Engineering
Volume 145, Issue 10
Abstract
This paper addresses the structural performance of a type of sandwich panels with lightly profiled thin steel skins filled with lightweight concrete. A series of experimental tests and numerical simulations were conducted on the composite panels subjected to concentric and eccentric compressive loads and flexural loads. Both results show that skin buckling is the governing criterion for the load carrying capacity of this structural component. Based on the contact buckling theory, practical formulas were developed for section capacity prediction of the composite panels. The experimental results, numerical simulation, and formula prediction results agree well with each other.
