Aseismic Studies On Staggered Truss Frame System

The coaction between superstructure and groundwork is an new subject.It is was becoming a hotspot problem during these years in theoretic and engineering practice along with more and more high-rise buildings. In conventionality designs, superstructure and groundwork have been regarded as two mutual independence structures to caculated. It is very different with engineering practice in stress and transmutation to ignore the coaction of superstructure and groundwork, and it is not safe and economy enoughThis thesis concludes the methods and results of domestic and overseas researches, make a key study on the stress performance of the coaction of several structures such as frames ,floors and groundworks under the vertical and wind load, use the finite element method to analyzed the stress capacity in the coaction of frames ,floors and groundworks.This thesis completed some work as follows:1. comprehensively introduce the theory about how to analyze the coaction ;2. use the agglomerate method of sub-structures to build up coupling model under the coaction of superstructure& frame and groundwork;3. use the finite element method to analyzed and explored the frames and groundwork, such the stress capacity ,internal force changing rule and so on.
