超重荷载平板结构预应力施工测试研究

Study on Construction Measurement of Prestressed Concrete Flat Slab Structures under Overweight Load

对苏州某工程预应力混凝土平板结构的预应力施工进行了测试研究。研究表明:该预应力平板结构在施工过程中性能良好,加设的上/下翻梁能够改善平板的受力性能,在超重荷载下现行规范的设计方法仍是可行的,其中关于预应力束张拉伸长值和平板有效翼缘宽度的规定也是合理的。

Construction measurement has been done on a prestressed concrete flat slab project in Suzhou, showing that, performance of the prestressed slab was good in the course of constructing, beams added to the slab can improve its capability, the design methods of the standard are practicable under such a overweight load, and the value of extension and effective width of the flange are believable.
