摘要
通过工程实例,说明井字梁的预应力配筋计算,不能仅依靠内力计算得到的内力包络图直接进行预应力配筋,还要考虑预应力平衡荷载在结构中的二次分配,预应力筋在井字梁中的布置要综合考虑构件弯矩的大小和荷载类型,在井字梁的各肋梁中预应力配筋数量要尽量均匀。
Based on a pre-stressed concrete cross beam structure,explain that the calculation of tendons in each beam not only depends on the bending moment envelope curve but also the twice moment distribution of balanced load is explained. The moment and load types should be considered when disposing the prestressed tendons.The number of the pre-stressed tendons should be uniform distributed in every beam.
