火灾后全取代率型钢再生混凝土梁抗弯性能
Studyon Bending Performance Steel Reinforced Recycled Aggregate Concrete Beams With Full Substitution Rate After Fire
摘要
Abstract
In order to study the flexural performance of recycled steel reinforced concrete(SRRAC)beams with full substitution rate after fire,the finite element model was used to analyze the effects of fire time,recycled coarse aggregate substitution rate,steel and recycled concrete strength parameters on the flexural properties of the components.The results showed that the fire time had a significant effect on the flexural performance of the components,and the concrete bearing capacity decreased by 17.9％～29.4％when the fire time was 30～60 min,and the concrete bearing capacity decreased within 10％when the fire time was more than 60 min.The substitution rate,steel strength and concrete strength had little influence on the bearing capacity.There was little difference in the internal temperature of the components between the same fire time and different substitution rates.关键词
