According to the problems in structural design of underframe, it analyzes the problems should be noticed including sample of bottom height?layout of quake-proof wall?ratio of rigidity?edge member and introduces right means to settle the problems.

This article , combined with a practical project design ,analyzes the distortion characteristics of column supported sheer-wall structure of high-rise buildings ,and concludes a method to calculate the bend yield and the utmost yield of a structural member ,in view of the functions of concrete and steel bar of edge member .

The requirements for edge member steel and vertical distribution steel of each wall segment are considered during steel arrangement.

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

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.

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.

Based on the current achievements,the defect of present work and the problems needing further study were pointed out,and a new kind of welded beam to column connection details of HCWs with steel boundary element in shear walls was proposed,which was simple in details and in construction.
