ABSTRACT
Taking a six-storey frame structure as an example, due to the large deviation of the protective layer of negative moment reinforcement in excess of the allowable deviation in a floor on the fourth floor, in order to ensure the safe use of structural engineering and reflect the most unfavorable loading factors, this paper uses the hierarchical load method, static load in the floor in situ safety inspection, measurement of the load, deflection and residual strain of concrete site casting such as indicators, and theory of contrast. The experimental results and theoretical results are discussed and analyzed to provide a reference for similar projects in the future.
