Structural deformation monitoring method for light steel structure fabricated building

Abstract

The invention discloses a structural deformation monitoring method for a light steel structure fabricated building, and the method comprises the following steps: 1, collecting the displacement of a wall frame column, the displacement of a wall frame beam, and the displacement of a connection node according to a sampling period, and enabling the collected displacement to serve as deformation data; 2, obtaining a real-time deformation value of the light steel structure fabricated building according to the collected two adjacent deformation data, and obtaining a fracture coefficient; 3, obtaining a fracture score according to the fracture coefficient; step 4, if Y is less than 5, determining primary deformation; if Y is larger than or equal to 5 and smaller than 7, secondary deformation is achieved; if Y is greater than or equal to 7, determining third-level deformation. According to the deformation data of the light steel structure fabricated building, whether the structure is deformed or not and the deformation level are judged, and the method has the advantage of improving the accuracy of structure monitoring.

Description

Technical field [0001] The present invention relates to the technical field of prefabricated buildings, more particularly, the present invention relates to a light steel structure prefabricated building structural deformation monitoring method. Background [0002] Prefabricated building refers to the use of prefabricated components produced by the factory assembled at the site of the building, generally using standardized design, factory production, assembly construction, is a new type of building production mode that can realize the sustainable development of energy saving, environmental protection and full life cycle value of the building industry. [0003] Prefabricated buildings are mainly divided into prefabricated concrete structure prefabricated buildings, steel structure prefabricated buildings and wood structure prefabricated buildings, of which steel structure prefabricated buildings can be divided into three sub-industries: light steel structure prefabricated building...

Problems solved by technology

[0005] At present, the country is vigorously promoting the construction of new countryside. Due to its advantages of energy saving, environmental protection and low basic cost, light steel structure prefabricated buildings have become the first choice for new housing construction. Most of the light steel structure prefabricated buildings are 1-3 However, in the existing demand, low-rise buildings are gradually unable to meet people's needs. In the construction of light steel structure farm houses, cold-formed thin-walled light-gauge steel structures are currently used as the main structure, but cold-formed thin-walled The light steel keel is an open structure with a thickness of about 0.8 mm. It has defects such as poor corrosion resistance, poor durability after corrosion, and low strength of the light slurry in the middle filling layer, which is more likely to cause bending deformation or partial fracture of the steel structure. , therefore, in the construction process of light steel prefabricated buildings, it is urgent to develop a method that can monitor the structural deformation of light steel prefabricated buildings
