【摘要】 以咸阳职业技术学院第二学生食堂为例,对高烈度区框架结构方案进行比选,结果表明,消能减震方案比传统抗震方案更合理,并对框架结构消能器比选、减震目标确定方法、阻尼器参数合理选择、阻尼器合理布置进行分析,提出建议及实用方法,通过多条地震波时程计算,对实际阻尼比确定、层间位移角控制提出合理建议,以保证结构实现预期减震目标。更多还原

【Abstract】 The article compares different structure program for frame at high earthquake intensity area,according to the structure design of the second student canteen in Xianyang Vocational Technical College.The comparison shows that structures with energy dissipation are more reasonable scheme.Suggestions and useful methods are pointed out based on the analysis of different dampers,required value of damping ratio,reasonable parameters and better arrangement strategy of viscous dampers.At last,evaluation methods are presented for the practical values of damping ratio and the max story drift of damping structures according to time history analysis of different earthquake waves,in order to meet the goal of seismic performance.更多还原
