轻钢-钢纤维再生混凝土组合短柱轴心受压性能试验研究

Jianzhu Gangjiegou Jinzhan
提出了一种轻钢-钢纤维再生混凝土组合柱，为研究组合柱的轴心受压性能，设计了5组不同构造短柱试件进行轴压试验，包括1组型钢试件和4组组合柱试件。以截面构造、钢纤维掺入量和再生混凝土强度为变化参数，研究不同参数对组合柱破坏特征、荷载-位移曲线、承载力、刚度、延性的影响。结果表明：提出的轻钢-钢纤维再生混凝土组合柱构造可以改善轻钢柱的稳定性能，显著提高轻钢柱的承载能力；轻钢-钢纤维再生混凝土组合柱的承载能力随着钢纤维掺入量的增加而提高，钢纤维可约束再生混凝土裂缝开展，改善试件损伤和刚度退化 ...

端部带肋圆高强钢管超高性能混凝土柱抗震性能研究

Jianzhu Gangjiegou Jinzhan
为量化端部加劲肋对圆高强钢管超高性能混凝土（ultra-high performance concrete filled high-strength steel tubular， UHPC-HST）柱抗震性能的影响，以加劲肋的高度、宽度、数量为参数，对8个端部带肋圆UHPC-HST柱试件进行了低周反复荷载试验，探究了各参数对试件破坏形态、滞回曲线、骨架曲线和抗震性能指标的影响规律。结果表明：各试件的滞回曲线饱满，具有良好的抗震性能，端部带肋试件的承载能力与耗能能力明显高于无肋试件的承载能力与耗能能力 ...
