| The lightweight autoclaved aerated concrete plate has many excellent material and technological properties with production and industrialization of high degree of construction application. In recent years, it develops rapidly and is widely applied, especially common in the frame structures as inside or outside walls. At present, the related application of technical regulations and the standards for the design of the atlas are well improved, and the lightweight autoclaved aerated concrete plate production line has been established in many districts.In order to research AAC wall panel and its connection joints by force performance, based on the principle of the finite element analysis, using the structural analysis software ANSYS15.0, totally 30 circumstances are calculated that the stress situation of the lightweight autoclaved aerated concrete walls and joints when the structure vertically or horizontally offsets 5 different displacement angles with hook bolt, steel anchor, built-in anchor 3 different connections.Analysis shows that with different angular displacements produced by the structure of the horizontal or vertical migration, each floor wall stress distribution is similar regardless of hook bolt, steel anchor or built-in anchor 3 different connection joints. The stress on lateral wall panels is greater than the stress on longitudinal wall panels. The stress on marginal transverse wall panel is larger than the stress on inner transverse wall panel. Extreme value of the stress appears at the bottom of the lateral structure transverse wall and the stress gets progressively smaller as the height increases and tends to be evenly distributed. The rigidity of the structure lateral offset and the way of the joint connection has obvious influence on the maximum stress of the wall panels. With same offset direction and displacement angle, the bigger force design value of bearing capacity of the joint result in bigger maximum stress of the wall panels; with same joint connection type and displacement angle, the bigger rigidity of the structure lateral offset result in smaller maximum stress of the wall panels. When the structure offsets horizontally, the 3 types of the connection joints all ensure a reliable bearing performance with few joints damaged. |
