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.

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.

frame column and the shear wall is studied, the failure mechanism and energy dissipation mechanism of moderate and tall shear wall with R.

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.

Discussion the seismic design of frame plus a small amount shear wall structures;

DFM applied to shear wall structures with flexible bases;

According to the different heights of buildings, several improved cast in site shear wall structure types are proposed in order to overcome the existing shortcomings while maintaining the merits of the shear wall structures.
