ENTIRE ANALYSIS OF HIGH-RISE BUILDING STRUCTURE IN PRELIMINARY DESIGN STAGE
Preliminary design stage is a key time to high-rise building design because its structure form, structure system and main member dimension may be determined and the possibility to influ-ence construction cost may attain 70％～80％ in this stage. Based on building conditions in preliminary design stage, such as building function, stories, height, length/width ratio, height/width ratio, floor height and the maximum wind pressure, seismic intensity and site type, one of the estimation method for building structure behavior under these combine action is presented. In this method every storey in building is taken as the macro element. The menber in building, such as beam, column, wall and slab, is included in the macro element. Considering the contribution of each member, the macro element stiffness is established for each storey. Then the entire analysis of building structure is carried out following the finite element method. Comparing the analysis results, such as internal force, storey deformation with the usual analysis method, it is known that this entire analysis method can be used to estimate the behavior of building structure in preliminary design stage. And it is a useful tool to architects or structure engineer to estimate the applicability of structure layout.
