In normal use, with the development of time, the deterioration of materials and the continuous action of loads will cause performance attenuation. Among them, the cracks in reinforced concrete of building structures are the performance of durability limit state. When the crack width exceeds a certain width, it is considered that the structure does not meet the requirements of the normal use limit state, and the structure needs to be identified and strengthened. Therefore, it is very necessary to analyze the causes of cracks in building structures and how to avoid the formation of cracks.展开更多
