The Semi-Analytical Approach For Static And Dynamic Analysis Of The Parallel Shear Wall- Corewall Structure

The parallel shear wall-corewall structure is the widely used structure type during recent years. This kind of structure under static loads is analyzed,and the free vibration of the super tall building with the sort of structures is also analyzed by the semi-analytical approach in this thesis. The parallel shear wall-corewall structure is comparied on the cantilever structure, and the computed formula of the parallel shell wall-corewall structure with dynamic and static analysis is deduced in this thesis.In the static analysis of the parallel shell wall-corewall structure, using the semi-analytical approach, the function expression formula that the internal force and displacement is deriving. In the dynamic analysis of this structure, using the semi-analytical approach, the natural vibration frequency of this structure is required.Using the formula from this thesis, the swing flexibility matrix of random-leg shell wall is derived, thus the swing stiffness matrix is derived. On the bases of theory and method, a process is developed by MATLAB. The examples are analyzed applying the formula and process, whose results are compared with those of the method in succession from the first document and SAP2000. The analytical results show that the method in this paper which is calculated simply and satisfied the required precision is economic and valid. During deriving the swing stiffness matrix, the interrelationship of all stories is considered with the method in this paper. Thus the results of the method in this paper are reflected the practical situation of the structure more than those of the conventional continuous method.
