摘要

基于有限元软件ABAQUS建立了高温后钢管再生混凝土轴压短柱的理论模型

其中再生混凝土的应力—应变关系考虑了再生混凝土骨料取代率和曾经历的最高温度的影响

计算了高温后钢管再生混凝土轴压短柱的破坏形态、荷载—变形关系、承载力和组合弹性模量

计算结果与试验结果总体吻合较好。利用有限元模型对高温后钢管再生混凝土轴压短柱的荷载—变形关系进行了全过程分析

揭示了受力过程中钢管与核心再生混凝土关键位置的应力—应变关系及它们之间相互作用应力的变化规律。研究结果可为有关钢管再生混凝土结构的工程实践和规程制定提供参考。

Abstract

The theoretical model for axially loaded recycled aggregate concrete（RAC）filled steel tube（RACFST）stub columns after exposure to high temperature is developed on the basis of the finite element software ABAQUS

in which

the effects of the recycled concrete aggregate replacement ratio and the maximum temperature suffered are considered in the stress versus strain relationship of RAC.The theoretical model is used to predict the failure pattern

load versus deformation relationship

bearing capacity and composite elastic modulus of axially loaded RACFST stub columns after exposure to high temperature

and the predicted results generally agree well with the test results.The complete load versus deformation relationship of axially loaded RACFST stub columns after exposure to high temperature is analyzed using the finite element model

and the analytical results reveal the stress versus strain relationship of steel and RAC at several positions and the interaction stress between steel tube and core RAC under loading procedure.The achievements in this paper may be referenced by the related practice and code development of RACFST structures.
