Some problems as follows about the building are discussed, the choice of design codes, the working life used in subsequent design, the analysis of seismic effect, the determination of site categories, the modification of structure layouts and system, the reinforcement and strengthening for boundary restraint elements of shear walls, the reduction of reinforcement amount of the abandoned.

It mainly includes questions such as the applicabl e height of buildings,the wind load and earthquake action, horizontal and vertic al regularities,the seismic design grade of structural members,the end or corner element within shear walls, structure with transfer story, etc.

A computational method for curvature ductility of shear walls with confined boundary zones was established.

The confined boundary elements of the specimens are designed according to "Code for Seismic Design of Buildings" (GB50011 - 2001).

The confined boundary elements of the specimens were designed according to Code for Seismic Design of Buildings (GB50011—2001)and the cold rolled ribbed welded steel fabrics were used as the distributed reinforcements.

The use of shear walls with different boundary restraints is quite popular in practice,thus a group of 1/4 scale model of shear walls with three different kinds of boundary restraints(embedded column,column,flange) are tested under low frequency cyclic and reversed lateral loads in this paper.

To improve the seismic resistance of reinforced concrete masonry shear wall structure,7 pieces of restraint flange members and 1 piece of flange member without restraint were tested under axial compression load.
