Analysis Of Ceramic Concrete Insulation Sandwich Wall Under Low Cyclic Loading

Building energy efficiency is a global topic. The building energy-saving design is one of the most important topic that we need in-depth study in China. Therefore, improving the building envelope insulation properties is an important way to promote the construction of energy-saving construction. However, because new insulation materials of the wall has been extremely limited in the practical application, it is very difficult to be used in ordinary civil construction. Accordingly, how to find a new kind of self-thermal insulation composite sandwich wall, and this structure can solve the problem of the practical application at the same time, it has been a very important task for a Chinese civil engineer now.In this paper, The 16 groups of orthogonal test design method obtained the ceramic concrete optimum mix ratio(and the optimal mixture ratio determination is to ceramic concrete sandwich self thermal insulation wall mechanical properties and thermal insulation performance together to achieve optimal), according to the combined with the optimal ratio, through since the ceramic concrete pouring sequence made of ceramic concrete sandwich self thermal insulation wall.The kind of new structure has been designed, it has light weight, and meet the requirements of the seismic performance. This structure is self-insulation ceramic concrete sandwich wall. Firstly, the best mixture ratio of ceramic concrete can be obtained by orthogonal experimental design method, according to the best mixture ratio of ceramic concrete, we can do low cyclic loading test and finite element analysis simulation for the model of self-insulation sandwich wall. On the basis of the opening pore size and pore distribution on the polystyrene panel that is inside ceramic concrete slab, it is designed eight pieces of elf-insulation ceramic concrete slab. Through the low cyclic loading test of the self-insulation ceramic concrete sandwich wall, and the analysis of carrying capacity, hysteretic properties, deformation behavior, stiffness degradation characteristics, we analyze the Collaborative work performance, adhesion properties, failure modes of ceramic concrete and polystyrene board inside the self-insulation ceramic concrete sandwich wall. Moreover, while in the test analysis, we do finite element simulation analysis of the test wall by using ABAQUS. A kind of reasonable unit type is selected, and the appropriate constitutive relationship and failure criteria of the ceramic concrete are set. By analysis of the test, We can obtain the seismic performance and hysteretic behavior of self-insulation ceramic concrete sandwich wall board and synergistic deformation of ceramic concrete slab, steel wire mesh and polystyrene board.According to difference of the ceramic concrete strength grade, through the finite element software of ceramic concrete sandwich from thermal insulation wall seismic performance are analyzed..The results of this study showed that the ceramic concrete sandwich self thermal insulation wall under low cycle repeated load, wall cracks, crack distribution and wall cracks extending basic similar, ceramic concrete and steel wire mesh and polystyrene plastic board has good cooperative work performance, with the increase of the ratio of holes and hole aperture, ceramic concrete, wire mesh and polystyrene board adhesive performance is better. The synergistic performance better, ceramic concrete sandwich self thermal insulation wallboard of the seismic capacity is stronger. With the strength of ceramic concrete increases, the ultimate load and yield load increases; the limit displacement decreases, yield displacement becomes larger, with little change.
