不同构造条件下钢筋混凝土框架柱抗震性能试验研究
|
摘要
为研究不同构造条件下钢筋混凝土框架柱的抗震性能,本文结合现行抗震鉴定标准构造了3类钢筋混凝土框架柱进行低周反复加载试验。其中A0类框架柱构造满足非抗震设计要求,A类、B类框架柱构造分别满足《建筑抗震鉴定标准》(GB50023-2009)中A类框架结构和B类框架结构要求。试验结果表明,不同的构造措施会发生不同的破坏形态,为避免发生剪切斜拉破坏应限制A0类和A类构件的轴压比,实测的延性系数对比关系可供抗震鉴定选取体系影响系数时作为参考。
Three categories reinforced concrete columns with different details are tested under cyclic loading to investigate the effect of details on the seismic performance of reinforced concrete columns.The details of category A0 columns are non-seismic designed;The details of category A columns and category B columns are in accord with Standard for Seismic Appraiser of Building(GB50023-2009).The results indicate that the different details lead to different failure modes and a limit should be set on axial compressive ratio of category A0 columns and category A columns in order to avoid shear failure.The contrast of ductility in the test can be used for influence factor in seismic appraiser.
