摘要
为了探索配筋钢管混凝土柱省时省工的施工方法,通过轴心受压试验,采用基于性能的比较研究方法,研究了配筋钢管混凝土短柱在纵向钢筋不变的情况下不同环向箍筋间距对其性能的影响。经过对试验结果在承载力、变形和延性性能以及破坏模式等方面的分析发现,箍筋间距对构件的轴心受压性能没有明显影响,并得出结论:环向箍筋不是影响构件性能的主要因素,在施工配筋钢管混凝土轴心受压构件时可以适当增大箍筋间距以减少材料用量,加快构件制作速度。
In order to investigate a time and work saving construction method for reinforced concrete filled tubular column （RCFT）, compression tests of RCFT short columns which are formed with different-spaced lateral reinforcements are performed, and effect of spacing between lateral reinforcements on overall performance of the member is then studied using a performance-based-comparing research method. After a comprehensive analysis of bearing capacity, deformability, ductility and failure mode, it has been made clear that the differed spacing of lateral reinforcementshas no significant effect on axial compressive performance of the member, and it is concluded that the lateral reinforcement is not the main factor which affects the performance of the member and spacing between lateral reinforcements can be increased or number of lateral reinforcements can be decreased when construct the RCFT member subjected axial compression.
