摘要
基于性态的抗震设计理论在实际抗震设计中的广泛应用有赖于对其概念的完善。目前由于对各种结构体系没有合适的物理量去描述结构性态,影响了这一理论的应用。为此,通过一个1/4比例的10层砌块砌体模型结构的振动台试验结果,分析模型结构在输入地震动下的各种反应(结构加速度反应、结构速度反应、结构位移反应等)与结构破坏之间的关系,初步确定了适合于描述该类型结构性态的物理量:结构顶层与地面之间的相对位移和结构顶层绝对速度。
The wide application of performance-based seismic design theory in actual seismic design lies in perfecting its concept.At present,the application of this theory is restricted because there is not any suitable variable to describe performances of varied structure systems.This paper analyzes the pertinence between structural responses,structural acceleration,structural velocity and structural displacement,and structural damage under input ground motions,and preliminary get the variable adapt to characterizing the performance of high-rising small-hollow concrete block masonry structures:relative displacement between structure top floor and ground and absolute velocity at structure top floor by a shaking table test of a 10-floor block masonry structure model in 1/4 scale.
