摘要
方钢管混凝土组合异形柱是一种新型的结构形式。将废弃的建筑垃圾重新回收再利用,与方钢管异形柱组合成方钢管再生混凝土组合异形柱。本文主要研究用于方钢管再生混凝土组合异形柱中的再生混凝土的配合比设计,为方钢管再生混凝土组合异形柱结构设计提供理论依据。
Among CFT members,concrete-filled square tubes(CFST)are getting more popular nowadays.The construction waste is recycled with combination of the square steel tubular special-shaped column.This paper mainly studies the design of the mixture ratio of recycled concrete in the composite special-shaped column of square steel tube recycled concrete,which provides a theoretical basis for the structural design of the composite special-shaped column of CFST.
