【摘要】 基于性态的抗震设计(以下简称PBSD,国内也称为基于功能的抗震设计)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一个统一的划分结构性态水平的标准,影响了这一理论的应用。为此,通过一个1/4比例的十层砌块砌体模型结构的振动台试验结果,分析了谈模型结构在输入地震动下结构的破坏程度,根据结构的破坏程度及试验过程中模型的动力特性的变化情况,初步确定了该类型结构性态水平的划分方法,并给出相应于每一个性态水平的描述性态的物理量的取值。更多还原

【Abstract】 The wide application of performance-based seismic design in actual seismic design lies on perfecting to its concept. Now the application of the theory is restricted because the performance levels are not uniform to different structural systems. This paper analyzes the structural damage under input ground motions, gets performance levels of high-rise concrete block masonry structures and numerical values of variables adapt to charactering structural performances by a shaking table test of a 1/4 scale model of a 10-floor block masonry structure.更多还原
