With the rapid development of finite element technology, the use of computer simulation has become a means of research, more and more widely used in the field of building structures. The work of this extensive literature see, based on the use of more sophisticated finite element software ANSYS, with the help of Building Research Institute of Gansu Province《aerated concrete panels and roof panels of ordinary concrete circular lateral stiffness of the Test level》, around the roof to simulate the stiffness of the problem. This paper summarizes the existing research on the basis of, mainly for the following aspect:1,This paper describes the structure of aerated concrete research and development, discusses the problems of roofing history and present situation, the basis for the follow-up.2,This article refers to the role of the space distribution coefficient m and the shear stiffness of roof integrated GA roof level as a measure of load distribution and the stiffness index. To regulate the stiffness of the standard medium, compared by calculating the value of 6 m roof, GA range of values, that they have a roof to improve the integrity and level of stiffness, and structure and standard for future construction provides a theoretical basis.3,At present, based on ANSYS analysis of non-linear of reinforced concrete frame, beam element or link– element modeling are mostly used and therefore they can not reflect the impact of steel bar on the frame or simulate such acts of reinforced concrete. In this paper, SOLID65 solid element modeling of reinforced concrete roof, and discuss the project needs the best option.4,In this paper, empirical formula to calculate the horizontal displacement of roof space for the role of yi and distribution coefficient m and the roof of the integrated relationship between the shear stiffness of GA. With large-scale finite element software ANSYS, aerated concrete roof on the numerical simulation, Analysis of the horizontal displacement of roof, walls remote strain. and simulation results combined with the empirical formula to calculate the role of roof space allocation.
