Experiment and analysis on mechanical properties of reinforced concrete beam after fire;
火灾后配筋混凝土梁受力性能试验与分析
To solve the problems such as fire resistance design,assessment and repair after fire for centrifuge concrete-filled steel tubular(CCFT) columns,based on analysis on stress-strain relationships of steel and concrete in fire environments and after high temperatures,a finite element model for calculating fire resistance and residual strength of CCFT columns was established.
针对离心钢管混凝土结构抗火设计、火灾中受损评价以及修复等有关问题,通过对钢材与混凝土高温下与高温后的应力-应变关系的分析,建立了离心钢管混凝土短柱四面均匀受火及其火灾后的有限元分析计算模型,进行了火灾下与火灾后荷载-变形关系曲线全过程分析,结合离心钢管混凝土结构的常温极限承载力表达式,提出了ISO-384标准升温曲线作用下和作用火灾后轴压构件的极限承载力简化计算公式。
