内置铆接开孔冷弯薄壁型钢混凝土组合梁受弯性能研究

Jianzhu Gangjiegou Jinzhan
基于锁铆连接传力可靠、强度优异的特征，提出了一种新型的内置铆接开孔冷弯薄壁型钢混凝土组合梁。以底部铆钉间距、截面宽度为变量，对内置铆接开孔冷弯薄壁型钢混凝土组合梁开展了四点弯曲试验，考察了该组合梁的破坏特征、承载性能和延性指标，试验结果表明：新型组合梁受弯时表现出良好的延性性能；底部铆钉间距小的组合梁延性较差；增大截面宽度可提高组合梁的极限承载力。采用ABAQUS有限元软件对该组合梁进行参数分析，重点探究五大关键参数对其力学性能的影响：有无混凝土包裹、混凝土强度、顶部铆钉间距、底部钢板厚度及截面高度 ...

不锈钢筋-圆不锈钢管海砂混凝土构件受弯性能研究

Jianzhu Gangjiegou Jinzhan
为研究不锈钢筋-圆不锈钢管海砂混凝土构件的受弯性能，文中建立了该类构件的有限元分析模型。基于有限元典型算例，分析了其纯弯全过程的受力机理。并对该类构件进行了参数分析，系统研究了混凝土强度、钢管屈服强度、纵筋屈服强度、钢管含钢率和纵筋配筋率对该类组合构件纯弯性能的影响规律。研究结果表明：内置纵筋显著提高了该构件的抗弯承载力；且组合构件的抗弯承载力随混凝土强度、钢管屈服强度、纵筋屈服强度、钢管含钢率和纵筋配筋率的增大而增大；该组合构件的抗弯刚度随混凝土强度、钢管含钢率和纵筋配筋率的增大而增大 ...
