超高性能混凝土梁抗剪性能的研究进展

Research Progress on Shear Properties of Ultra-high Performance Concrete Beams

超高性能混凝土(Ultra-High Performance Concrete,UHPC)作为一种新型建筑材料已在实际工程中广泛应用,针对UHPC梁抗剪性能学者们开展了试验及理论研究,UHPC相关标准和规范正不断撰写及出版,但UHPC梁抗剪性能区别于普通混凝土梁,UHPC梁的抗剪承载力计算较为复杂。本文总结了UHPC材料力学性能和UHPC梁抗剪性能,以期拓宽UHPC在叠合梁中的应用。

Ultra-High Performance Concrete(UHPC),as a new type of building material,has been widely used in practical engineering.Scholars have carried out experimental and theoretical studies on the shear properties of UHPC beams.Relevant standards and specifications of UHPC are being written and published continuously.However,the shear capacity of UHPC beam is different from that of ordinary concrete beam,and the calculation of shear capacity of UHPC beam is complicated.This paper summarizes the mechanical properties of UHPC materials and the shear properties of UHPC beams to broaden the application of UHPC in composite beams.
