Computational prediction on structural behaviour of precast lightweight panel under axial load

Abstract

Precast system is getting popular in industrialize building system, demands of this product increasing every day. By using precast system more affordable and quality houses able to be constructed. Many previous and recent researches have been focused on precast lightweight concrete panel which provided more benefits than normal reinforced concrete panel. However, the structural behaviour of precast lightweight foamed concrete panel (PLP) had not been explored deeply by researchers. This study presents the results of the structural behaviour of the PLP panel under axial load in terms of its ultimate load, crack pattern, load-deflection profiles and strain distribution load bearing capacity by finite element analysis. The focus on this study is on the structural behaviour of PLP panel. A three dimensional non-linear finite element model was developed and analysed by ABAQUS Software. Results show that the proposed finite element model can be used as economical tool to study the structural behaviour of PLP panel.
