宿迁市教育大厦消能减震设计研究

对地处地震高烈度区的宿迁市教育大厦进行了消能减震设计。采用消能减震支撑框架结构体系代替传统的框架—抗震墙结构体系,进行了结构非线性时程分析,对消能装置的数量及布置进行了优化。分析结果表明,消能减震支撑框架结构在多遇地震作用下的层间位移能满足《建筑抗震设计规范》要求,在罕遇地震作用下具有更高的安全储备,表现出良好的抗震性能,可为高烈度区类似结构的设计提供借鉴。

Design of RC Frame Structure with Energy-Dissipated Braces in Suqian Education Building

Suqian Education Building, which locates in a region of high earthquake intensity with basic designed acceleration of ground motion of 0.3g, is designed by the method of energy-dissipation earthquake-reduction in this paper. The energy-dissipation braced frame structure system is used to replace the ordinary frame-shear wall structure system, the optimum number and location of the energy-dissipated braces in this building are studied. Calculation results of the nonlinear time-history analysis by SAP2000N software show that, the energy-dissipation braced frame structure can satisfy the requirements of "Code for seismic design of buildings", possess higher safety under seldom occurring earthquake, and has excellent aseismic behaviors. The design method suggested in this paper can be utilised for the design of similar projects in the region of high earthquake intensity.
