【摘要】 探讨了多层不规则框架-砖混组合结构的动态测试模型与方法,利用环境激励和脉冲激振的方法对湖北省黄石市政府办公大楼进行了综合检测,测量并分析了框架主体结构的动力学特性,对砖混结构的承重墙、梁和楼板等构件进行了局部损伤诊断,并就构件损伤前后的响应幅值和频率特性等进行了分析和比对,为结构的改扩建和抗震设计提供了有益的参考.更多还原

【Abstract】 The dynamic measure technique is developed for the multi-story and non-regular frame-brick mixed structures.An overall inspection was carried out to the office building of Huangshi government based on vibration testing method.The dynamic behavior of structure is analyzed,and the vibration frequencies and modes are obtained by the environment excitation and pulse testing methods.The damage identifications of structural members of bearing walls,beams and floors are studied,and the response properties of members are discussed.Some suggestions are proposed to improve the dynamic behavior and anti-seismic properties of structures.更多还原
