Abstract

As a product of the infrastructure era, old buildings have impeded urban renewal. The uneven level of construction technology in the past has led to the unpredictability of whether various old buildings can continue to be used and accept the reinforcement treatment. In order to solve these problems, the main components of the old building are sampled and tested by testing methods, including foundation bearing capacity, structural strength, crack development, structural size, etc. Then, according to the statistical principle, the reliability of each component is analyzed to obtain the 95% probability guarantee rate limit requirement under the normal function distribution law, which is regarded as the bearing capacity of the structure. Finally, the calculated bearing capacity limit is compared with the minimum bearing capacity required by the reinforced component specification. If it is met, the component meets the normal use standard; if not, the reinforcement is carried out. The research shows that the method can be used to analyze the monitoring results of the bearing capacity of each component quickly and effectively, and the bearing capacity assessment and reinforcement method can effectively help obtain the information of the components required for the reconstruction of the old building. The method is feasible and can bring great economic effects to the reconstruction of old buildings.
