Yellow River sullage porous brick can substitute for clay brick and be used as bearing wall material based on analysis of masonry compression strength,crack development and breakage feature.

Solid clay brick still prevails in the load-bearing wall materials in china.

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.
