摘要
本文研究预应力CFRP加固钢筋混凝土无梁楼盖的技术和设计方法,首先介绍预应力CFRP加固钢筋混凝土无梁楼盖的材料及加固方式,用等代框架法确定计算模型,计算荷载,按正常使用极限状态和承载能力极限状态的荷载效应组合分别计算板的内力。按正常使用极限状态的抗裂要求确定预应力CFRP的加固数量。最后给出屈服弯矩及极限承载能力的计算公式。
This article includes the designing method and technique which are used in reinforcing concrete slab -column by sticking prestressed CFRP sheets. First of all, author introduced materials and reinforcing manner, then used equivalency frame method to confirm account model and calculateal load and internal force of board based on the normal use ultimate state and carrying capacity limit state. Author confirmed the amount of prestressed CFRP sheets based on the resist crack demand of the normal use ultimate. In the end, calculated expressions of the curved moment and the limit carrying capacity were put forward.
