摘要
钢筋混凝土结构遭受大灾作用后,在决定修复受损结构以前,必须估计结构的残余承载能力,这需要了解高温作用后混凝土和钢筋的性能,其中高温作用后混凝土的本构关系是计算结构残余承载能力的基础.
When Reinforced Concrete structure is exposed to fire,the structure wil l keep integrity because of good fire resisting capability.become a n important problem.We decide to rep air the damaged structure.It requir es that we estimate the capability of concre te and reinforcing steel bar after being exposed to fire,the stress-stra in relation is the base of calculating the remain ed compressive strength.
