Structural Steel Grid of Gymnasium Load Safety Assessment
Summary (1) Definition: Steel structures refer to load-bearing structures composed of steel materials. In engineering, reinforced concrete structures that bear and transmit their own weight and loads are commonly referred to as concrete structures; while structures that bear and transmit horizontal forces (such as wind, snow, etc.) are known as steel structures.。
General Process for Safety Inspection and Appraisal of Steel Structure Factory Buildings:
Conduct on-site surveys to assess the type of house structure, number of floors, house address, year of construction, orientation of the house, general condition of the house's interior decoration, and the intended use of the house.
2. Review the steel structure layout, component dimensions, and floor heights of the buildings based on the provided drawings by the client; for buildings where design drawings were not provided, conduct on-site measurements of the existing upper structure layout, component dimensions, and floor heights, and draw structural diagrams.
3. Conduct inspections and appraisals of the current exterior damages to steel components in buildings, including cracks, damage, coating peeling, steel corrosion, joint injuries, welding appearance defects, and connection fastening conditions.
4. Conduct surface quality inspections on steel components in accordance with national standards using magnetic particle inspection or dye penetrant testing.
Structural Steel Factory Building Inspection Categories
Structural steel workshops are undergoing inspections. In our country, there are two categories of structural steel inspection technologies: one is the inspection of steel structures under construction by enterprises, and the other is the inspection of existing steel structures.
What are the different situations that require research into existing steel structure technical testing and on-site steel structure testing?
When encountering any of the following issues, a technical analysis and inspection should be conducted on the under-construction steel structure:
Inspection or acceptance of steel structures should involve understanding the quality status.
2. Doubts or disputes regarding construction management quality or materials
It is necessary to analyze the cause of the engineering accident and its impact on the structural reliability.
When encountering any of the following issues, the existing steel structure technology should be applied for analysis and inspection:
Structural Steel Safety Assessment
2. Steel Structure Seismic Assessment
3. Pre-repair Reliability Assessment of Steel Structural Components
4. Change of Use, Alterations, Addition of Floors, or Expansion of Existing Buildings Identification
5. Impact Assessment Due to Disasters and Environmental Erosion
6. Doubts or disputes regarding the reliability of existing building steel structures.
