Thermal Insulation Performance and Reliability of the “Structure-Insulation” Integrated Wall Panel (SIW) for Storage Grain Bungalows

The traditional brick bungalow is not conducive to long-term grain storage because of its poor thermal insulation. In this paper, a new type wall element for bungalows with both load-carrying and insulation functions, called “Structure-Insulation” integrated panel (SIW), proposed improving the environment. To study reliability SIW under multivariable randomness availability different zones, finite model was established based on test. Then, failure criterion heat transfer coefficient as key point 1,000,000 sampling calculations were carried out by Monte Carlo method. discussed sensitivity random parameters quantified. performance test shows that coefficients two designed panels compared are reduced 45.81% 56.13%, respectively. thickness sensitive mostly performance, correlation 0.877. When 80, 94, 107 mm, can meet limit requirements granary enclosure structure 0.59, 0.53, 0.46 W/m2·K, indexes 3.08, 1.82, 1.75, research results provide an important reference design, optimization, application in
