Influence of slenderness ratio on the structural performance of lightweight foam concrete composite panel

摘要

In this research paper is reported the analytical and experimental investigations on the influence of slenderness ratio on the structural performance of lightweight foam concrete composite panel (LFCCP). Six full-scale tests of LFCCP panels differing in thickness were implemented under compression load. Compression load strength, load-strain profiles, load-deflection curves, influence of slenderness ratio, deformation, cracking patterns and classic modes of failure under incremental compression loads were analysed and deliberated. Nonlinear finite element modeling (FEM) using commercial software named LUSAS was used to simulate the structural behavior of LFCCP. The calculated ultimate compression strength capacity using empirical formulas established by many researchers, to expect the ultimate strength capacity of composite LFCCP panels were in comparison with the laboratory test results and FEM data attained; thus, a substantial agreement with the FEM data that were obtainable with a reasonable degree of accuracy, presented the increase in slenderness function.
