Description

An edge-constrained flexible infill shock-absorbing wall structure

technical field

The utility model relates to an edge-constrained flexible filling damping wall structure, which belongs to the field of building construction.

Background technique

The traditional wall-building process is to mark the elevation line on the structural wall column according to the design drawings, and then select the appropriate brick arrangement method according to the height of the wall and the thickness of the mortar joint, and pre-embed the connecting wall on the masonry and reinforced concrete frame columns. Reinforcements are built after the tensile test. Due to the high rigidity of the traditional masonry infill wall, it can withstand a large earthquake force when an earthquake occurs. At the same time, due to the low strength and poor deformation capacity of the masonry infill wall, the masonry infill wall is easily damaged when an earthquake occurs. In addition, traditional masonry infill walls have different expansion coefficients at different temperatures, so there are some complex interaction forces between masonry and frame structures. For example, in northern my country, the temperature difference between day and night is large, and the temperature changes throughout the year are particularly large. Some shear deformations will occur in masonry filling walls at different temperatures, resulting in damage to the stressed structure of masonry.
