摘要
本文引用一种解决混凝土局压问题的新方法——预应力筋约束混凝土局部受压构件,分析了预应力筋作用下混凝土局部受压工作原理,并介绍了拉压杆模型法计算构件承载力.混凝土局部受压构件在预应力钢筋约束下,不仅承载力明显提高,大大减少由局部受压产生的工程事故,而且钢筋可循环利用以达到节约钢材的效果.
This article describes a new method for solving concrete problems prestressed tension constrain partial compression members. Analyse working mechanism of partial compression concrete constrained by prestressed ten- sion. Meanwhile, strut - and - tie model is building in partial compression members to calculate bearing capacity. U- sing prestressed tension to constrain partial compression concrete members not only greatly enhance bear capacity, but steel can be recycled to achieve the effect of saving steel in construction.
