摘要:
通过对9根钢板笼混凝土组合柱和1根钢筋混凝土柱的偏压试验,研究钢板笼混凝土组合柱偏压的基本力学性能,并分析不同参数对钢板笼混凝土组合柱偏压力学性能的影响.结果表明:钢板笼混凝土组合柱的偏压破坏特征与钢筋混凝土柱基本相同,试件中部符合平截面假定,横向曲线近似正弦半波曲线;钢板笼混凝土组合柱与钢筋混凝土柱相比,耗能可提高110%,延性可提高48%;偏心距是影响钢板笼混凝土组合柱偏压承载力的主要因素,长细比在4~10范围内对承载力影响不大;随着含钢率增大,试件的承载力增大,但提高的幅度逐渐减小.
Abstract:
The mechanical properties of prefabricated cage system(PCS)composite column under eccentric compression were experimentally studied by 9 PCS composite columns and 1 ordinary reinforced concrete(RC)column, the influence of different parameters was also discussed. The result indicates that the form of destruction of PCS composite column is similar to RC column; the plane section assumption is valid in the middle part of the column; the deflection of column is close to half-wave sinusoid; PCS composite column has about 110% higher capacity of energy dissipation and 48% higher ductility than RC column. Eccentricity is the main factor of bearing capacity of PCS composite columns. Slenderness ratio in the range of 4-10 has little effect on the bearing capacity. The bearing capacity of the specimen increases with the increase of the steel ratio, but the increase ratio gradually reduces.
