Study On The Seismic Performance Effect Of Wide Flat Beam And Shear Walls For The Frame

In the earthquake area of Wenchuan, a large number of houses have collapsed causing substantial losses for the state and the people. After the experts survey on the disaster discover that it appears plastic hinges in the course of large earthquake frame structure in the column end, and the design target that the expected " strong column and weak beam " did not come true.Aiming at the column end some plastic hinges, the author refers to the related literature, and finds many scholars have raised about help achieve the " strong column and weak beam " method. After the selection, the author will focus on the effect of wide flat beam and shear wall on column hinge yield mechanism. Based on the conventional frame model, wide flat beam frame model, and adding proper amount of shear wall frame model are compared and analyzed, this article has the following work.I.According to a10code for seismic design of region of8intensity, two,0.20g grade reinforced concrete frame structure by using conventional PKPM structure design software to build3D space and the analysis of SATWE and STAT-S.II.Application of EPDA and PUSH to8degrees two reinforced concrete space frame model under rare earthquake dynamic elastic-plastic time history analysis, pushover analysis.III.According to the10seismic design code using PKPM structure design software was set up for the same condition of reinforced concrete wide flat beam model, frame shear wall model, and SATWE analysis.IV.Application of EPDA and PUSH on the wide flat beam model, frame shear wall model under rare earthquake dynamic elastic-plastic time history analysis, pushover analysis.V.Comparison of three kinds of model established by dynamic time-history analysis and static analysis results, determine the wide flat beam and shear wall for structure strong column and weak beam yielding mechanism to achieve the effect.
