STUDY ON DEFLECTION AND CRACK OF ROOF PLATES WITH CORRODED REINFORCEMENT AND DETERIORATED CONCRETE
-
摘要: 对已出现钢筋锈蚀和混凝土破损的6块大型屋面板进行了试验研究,分析了不同破损特征及不同锈蚀度下大型屋面板的变形和裂缝分布,为评价服役屋面板的刚度提供了试验依据。Abstract: Through the experimental study on 6 concrete roof plates with corroded reinforcement and deteriorated concrete, deflection and crack distributions of the roof plates with the different characters of deteriorated concrete and different degrees of corroded reinforcements are analyzed. It provides an experimental basis for appraising the rigidity of roof plates in using.
