In seismic region,the appropriate structure types of highrise building with ground floor shop are generally as follows:the bottom framed shearing wall and top masonry structure,the multiple storey internally framed structure,the multiple storey completely framed structure,and the multiple storey masonry structure etc.

A successful highrise building fundus space is not only a favorable transition for architect and cities, but also itself a beneficial component part of urban public space.

The paper discusses several key technologies of the foundation design of high building with multiple towers-huge bases,including foundation settlement control method,such as post casting zone construction,foundation settlement joint and overall design of the foundation,and variable rigidity design method,and design considering superstructure-stiffness.

The high-level commercial building performance-based fire design of the existing uncertainties, which runs through performance-based design process from beginning to end, performance-based fire on the building\'s design quality, safety and so on are important.
