| 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．

| Abstract: | 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. |
