预应力筋与钢筋网片的局压承载力研究

Local Central Bearing Capacity Research of Prestressed Reinforcement and Reinforced Mesh

本文采用预应力筋与钢筋网片的局压模型,通过分析素混凝土在植入预应力筋与钢筋网片后的局压破坏形式,对比不同位置时的极限承载力,找出最合适的预应力筋与钢筋网片形式,便于推广到工程实际当中.

The local compression model of prestressed reinforcement and reinforced mesh was used. Through the a- nalysis of concrete compression failure forms in the implantation of prestressing tendons and bar - mat reinforcement after the local compression failure, compared different position limit bearing capacity, find out the most suitable pres- tressed reinforcement and reinforced mesh, easy to spread to the engineering practice.
