Study on Design Measure of Seismic Capacity Design in R.C. Mega-Frame Structures

Abstract:

This paper explores the design method of several typical mega plane frames, with the variables being the combination of varying amplification coefficient of moment at bottom sections of ground floor columns of the secondary frame on the main beams. The elastic-plastic dynamic analysis program Drain-2d+ of the plane structure is used to carry out the elastic-plastic time-history analysis for each typical mega-frame under the earthquake action. Based on the analysis, the deformation characteristics of the mega-frame, the emerging of the plastic hinge and the weak point of the overall structure under the earthquake action is developed, from which the correct method of obtaining the design value of amplification coefficient of moments at bottom sections of ground floor columns of the secondary frame on the main beams is concluded. The reasonable design values are recommended as the basis to provide some suggestions for the design of the reinforced concrete mega-frame structure.
