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 the standard of performance level of reinforced concrete structures at home and abroad, the performance level of RC shear wall is divided into five grades: good use, continuous use, temporary use, life safety and near collapse. According to the four earthquake action levels, the seismic fortification targets of reinforced concrete shear walls are established and the formula of force displacement angle under different performance levels is deduced. Based on the statistical analysis of 90 test data in China, the quantitative limit of performance index is obtained by force displacement angle.
