The compression mechanic performance of 3 concrete sandwich load-bearing panels under axial forces is studied using finite element analysis software ANSYS.

Underpinning beam should be designed before the bearing wall removed in brick wall load structure.

uch a problem as the collision or overlap of isolating foundations caused by the over-closed distance between columns or between column and bearing wall often occurs in the design of civil architecture frames or bearing walls,ect.

Combining with the existed question in residential fitment,several aspects such as the demolition of non-load-bearing wall,holing and notching of bearing wall,sealing balcony and floor fitment were discussed,the damage of above residential fitment to structure was analyzed,so as to provoke the more attention of related department and tenement,to ensure safety of life and loss.

The successful application of steel structure to the process of tearing down and rebuilding the main wall indicates the advantages of steel structure.

On the base of theoretical and experimental research and combining the application in engineering, the mechanical performance of concrete multi-row bore pint-size block in main wall summering engineering is analyzed and researched.

Using finite element analysis soft ware ANSYS to analyse the restriction moment on the beam end of bearing longitudinal walls with casting bearer,the result of finite element analysis is compared with the moment on the beam end calculated with the rigid joint of frame.
