钢筋混凝土剪力墙性能指标限值研究

RESEARCH ON PERFORMANCE INDEX LIMIT VALUE OF REINFORCED CONCRETE SHEAR WALL

结合国内外钢筋混凝土结构性能水平的划分标准,将钢筋混凝土剪力墙的性能水平划分为良好使用、继续使用、暂时使用、生命安全和接近倒塌五个等级。针对4个地震作用水平,建立了钢筋混凝土剪力墙的抗震设防目标,并推导不同性能水平下受力位移角计算公式。在统计分析国内90个试验数据的基础上,得出以受力位移角的性能指标量化限值。

Combining with performance grades of reinforced concrete structures at home and abroad,the seismic performance of reinforced concrete shear wall structures can be divided into four levels： normal service,continual service,temporary service,life safety and collapse prevention.Considering four seismic levels,the structure performance objectives and seismic fortification criteria were formed.The equations to calculate physical displacement of shear wall specimens for different performance objectives were derived.Based on the statistical data of the experiments and results of reinforced concrete shear wall structures,quantization indexes of different performance levels of R.C shear wall structure were put forward.
