Study on Mechanical Properties of Cavity Heat Insulation Walls Out-Of-Plane Loaded

Abstract

The cavity heat insulation walls as a major form of multiple thermal insulation walls is the development of the energy-efficiency building materials. Attention is taken to describe the mechanics properties of cavity walls under out-of-plane load. In this paper, Mechanical model is developed for masonry walls out-of-plane loaded, and the analytical expressions about the internal force and deflection are abtained using the orthotropic theory. Limit deflection of interior walls under vertical and horizontal loads is calculated by mathematical software (MATLAB) and is simulated based on finite element analysis software (ANSYS) respectively. Finally, the results indicate that vertical loads and elastic modulus have great impact on the maximum deflection of masonry walls. Numerical computations show that the shell element of SHELL63 is well used in analysis of the internal force and deflection of masonry walls out-of-plane loaded.
