Seismic Analysis Of Small High-rise Structures

Framework, frame-wall structure and shear wall structure are commonly used in small high-rise structures architecture. The force features and the abilities to resist horizontal loads, lateral stiffness and seismic performances of these systems are all different. This paper used a residential building as an example, which according to elastic and elastic-plastic time-history analysis principles. For the structural characteristics, it used the finite element analysis software SAP2000 to lay a theoretical foundation for the selection of small high-rise structures in the areas of the structural system under seismic force and deformation properties which are calculated and analyzed.This paper made a comparative analysis of the small high-rise structural system in seismic force under the action of the performance, and discussed the impact of the performance of seismic response of structures, primarily done in the following aspects of work.1. A theoretical analysis of elastic phase and elastic-plastic stage's deformation characteristics which under the action of horizontal force, and the derivation of the equations of motion of the structure.2. Using Sap2000 to do a finite element analysis of small high-rise frame structures, frame-wall structures, and shear wall structure.3. Comparative analysis of three kinds of model calculations.4. Dynamic time-history analysis methods on three kinds of structural systems for seismic response analysis, analyzing the structure of incentives under the same seismic response, and selecting the EL-Centro wave analysis of structures under earthquake time-displacement response and timely way the results of internal forces.5. Analysis of the response to the performance of the small high-rise shear walls under the seismic action of seismic waves.6. The results show that: shear wall structure is better than the frame-wall structure and frame structure, due to coordination between the role of each floor, and making the apex of lateral shear wall structure and the vertex maximum inter-story drift angle can be reduced, this is very favorable for seismic.
