摘要
进行了7根三面受火受弯试件自然冷却后承载能力的试验研究,了解了钢筋类型、混凝土保护层厚度和试件截面尺寸对自然冷却后受弯承载力的影响程度,为火灾后混凝土结构的鉴定和评估提供依据。
RC beams after cooled down from high temperature on three surfaces and RC beams in room temperature were experimentally investigated. And the effect of steel bar type, concrete cover and cross section on the carrying capacity was analyzed. This may be beneficial to the appraisal and assessment of RC structures after fire.
