Abstract

The invention discloses a method for detecting the vertical structure load of an existing building by intercepting a concrete structure test piece. The method comprises the following steps: intercepting the concrete structure test piece from the vertical structure of the existing building, and detecting the vertical strain of the concrete structure test piece by adopting a vibrating wire strain gauge so as to calculate the magnitude of the vertical load borne by the vertical structure of the building. The concrete structure test piece is cut from the side surface of the vertical structure of the existing building, the strain of the concrete structure test piece in the vertical direction is measured through the vibrating wire strain gauge, then the vertical load of the existing building structure is calculated through the elastic modulus formula, damage to the building structure is small, implementation is convenient, the result reliability is high, and good use value is achieved in theengineering field. Meanwhile, the method provides important data support for building reinforcement design, and particularly plays an important role in building pile foundation deviation rectification and reinforcement engineering.

Description

technical field

[0001] The invention relates to a method for detecting the vertical structure load of an existing building by intercepting a concrete structure test piece. Background technique

[0002] With the development of the economy and the expansion of the population, land resources are increasingly scarce. In order to meet the needs of people's economic activities and living, more and more high-rise buildings have been erected. In theory, the vertical structure of a high-rise building bears its vertical load evenly, and the magnitude of the load can be known through calculation; however, in practice, it is often caused by factors such as uneven settlement of the foundation of the building. The tilt of the building caused the redistribution of the vertical load of the building structure, and the vertical load of each vertical load-bearing structure changed greatly.

[0003] In order to ensure the structural safety of the building, it is necessary to reinforce and rect...
