试验研究证明,装配式梁柱框架施加竖向预应力,不但可以简化节点构造,而且能使装配式节点具有现浇梁柱框架节点的性能和提高抗裂度.
Experimental studies have shown that the application of vertical prestress to the fabricated beam-column frame not only simplifies the construction of the node, but also enables the fabricated node to have the performance of the cast-in-place beam-column frame node and improve the crack resistance.
