基于标准ISO 15701内容对鞋面革、家具革及汽车革的颜色迁移程度进行了测定,并同时检测了样品的湿摩擦色牢度。颜色迁移检测结果表明,所测汽车革的颜色迁移程度最低,平均结果为4~5级,鞋面革颜色迁移显著,平均结果为3级,家具革颜色迁移平均结果为4级。湿摩擦色牢度结果表明,所测鞋面革平均为2~3级,家具革平均为4级,汽车革平均为4~5级。两种颜色牢度的综合分析表明:颜色迁移程度不能反映摩擦色牢度的结果,而耐摩擦色牢度可以反映出颜色迁移的程度,即颜色耐摩擦色牢度差,将容易发生颜色迁移。

为研究焊接复合箍筋钢筋混凝土短柱的抗震性能,首先进行了5根配置焊接复合箍筋的钢筋混凝土短柱和3根普通箍筋的钢筋混凝土短柱（作为对比）抗震拟静力试验,并对其破坏形态、滞回曲线、骨架曲线、延性及耗能指标、强度刚度退化、抗剪承载力等进行了对比分析.结果表明,焊接复合箍筋钢筋混凝土短柱与普通箍筋短柱的抗震性能各项指标两者基本一致或稍有提高,其中破坏过程相似,呈现出剪切破坏及部分剪切粘结型破坏形态,各构件滞回曲线表现出明显的＂捏拢＂效应,延性、耗能能力及强度刚度退化速度两者相当,同时均为明显的脆性破坏,但其位移延性均在3.58~5.52之间,表现出较好的延性抗震能力,表明焊接复合箍筋可用于工程实践和推广.

为了研究焊接箍筋钢筋混凝土构件的受剪性能,对6根焊接箍筋钢筋混凝土框架短柱和3根普通箍筋钢筋混凝土框架短柱对比试件展开低周反复加载试验,以及5根焊接箍筋和4根普通箍筋钢筋混凝土梁斜截面受剪性能试验,分析混凝土强度、箍筋配箍率、轴压比和剪跨比对焊接箍筋钢筋混凝土框架柱和梁受剪承载力的影响,并对比焊接箍筋与普通绑扎箍筋钢筋混凝土框架短柱和梁的受剪承载力的区别。结果表明:焊接箍筋与普通绑扎箍筋钢筋混凝土框架短柱和梁的破坏形态基本相同,并且焊接箍筋钢筋混凝土框架短柱和梁的极限抗剪承载力高于普通箍筋钢筋混凝土框架短柱和梁。另外,用现行的GB 50010—2010《混凝土结构设计规范》规定的框架短柱和梁的抗剪承载力计算公式计算的结果偏低,因此进一步结合试验数据进行分析并拟合出焊接箍筋钢筋混凝土构件抗剪承载力计算式,计算值与试验结果较吻合,可用于工程设计。
