Thermal Stress Performance Analysis for a New External Wall Insulation System

Abstract:

Article Preview

In this paper, two models are taken as subjects, one being a small frame exterior composite insulation system with the shear key, the other being the system without the shear key. In extreme high temperature conditions in summer, the small frame exterior composite insulation system temperature stress and strain are analyzed with numerical simulation using finite element method. Results show that shear key can effectively reduce the stress concentration, weaken the stress peak by nearly 50% and reduce the deformation by nearly 50% as well, thus effectively reducing the probability of crack cracking, improving the durability and extending service life.
