In order to provide a reliable theoretical basis for the formulation of the reinforcement plan, it is necessary to conduct an on-site assessment based on the reliability status of the structural members. The whole process of steel structure design and reinforcement includes the calculation of steel structure bearing capacity, the processing of structural parts and the drawing of construction drawings.
According to different requirements, the scope and degree of reinforcement are often different, and attention should be paid to the coordination of the reinforced part with the original structure. The key points of steel structure design and reinforcement are analyzed in detail below.
1. Fully understand the steel structure design, reinforcement, material performance optimization and system.
In the process of strengthening steel structure factory buildings, we must first understand the reliability of the factory building, including the performance of steel structure materials, structural systems, structural defects and damage. Organize experienced and highly skilled professionals to conduct a unified study on these issues, analyze the current status and bearing capacity level of the steel structure workshop, and lay the foundation for the next step of reinforcement and optimal design.
2. Steel structure design and reinforcement optimization, choose economical, reasonable and reliable reinforcement measures.
The selection of steel structure design reinforcement scheme needs to fully consider the stress state of the structure and the stress characteristics after reinforcement.
Starting from ensuring the rationality and reliability of the structure, economical and reasonable reinforcement measures were selected. For example, new and old structure or material connection technology, combined with the existing reinforcement level, try to consider comprehensive technical indicators.
In addition, in the optimization design of steel structure reinforcement, effective measures should be taken to reduce the negative impact on the surrounding environment and adjacent buildings, and shorten the construction period.
3. The design and reinforcement of the steel structure optimize the bearing capacity of the original structure.
In order to avoid damage to the original structure, the load-bearing capacity of the original structure should be used as much as possible during the reinforcement process. Reliability analysis and testing of the load-bearing components of the plant to fully understand the existing load-bearing capacity. Then, according to the test report, retain and utilize more original load-bearing components. Because the large-scale dismantling of the steel structure workshop is easy to bring serious damage to the components, and the connection between the new and old structures is difficult, this will affect the reinforcement effect to some extent, thus will be a huge safety risk for the steel structure workshop to be used .
4. Design and reinforcement quality control of steel structure in construction
In the process of strengthening and optimizing the design of the steel structure, it is necessary to strengthen the detection of the actual structure, accurately grasp the actual situation and the destruction of the existing structure, and eliminate hidden dangers in real time.
Technical measures to strengthen quality control include manufacturing, welding, installation, bolting, anti-corrosion, fire-resistant paint coating, and installation of special-shaped steel plates. In the process of strengthening and optimizing the design of the steel structure, it is necessary to check the quality defects of the structural components and find out whether the use does not conform to the test results or found in the inspection, so timely remedial measures should be taken to ensure reliability and effectiveness Strengthen the program to the maximum.
