Jingzhou Residential Housing Structural Function Renovation Safety Assessment Content
1. Jingzhou Residential Housing Structural Function Renovation Safety Assessment General Inspection Content
1) Investigate the construction information of the house.
2) Investigate the historical background of the property.
3) Review of architectural construction drawings
4) Inspect the structural arrangement, construction connections, and the structural system of the building.
5) Inspect the building for tilting and uneven settlement.

2. Structural system changes should be inspected for content
When the structural or functional changes of a building result in a transformation of the entire structural system, or even if they are localized but significantly affect the load-bearing condition of the entire building, a detection is required as follows:
1) Analyze the structural and functional alteration plans, as well as technical requirements provided by the client.
2) Conduct material mechanical property tests on the components of building structures, inspect areas of structural changes and increased loads, and determine the inspection items based on the requirements of structural calculations.
3) Based on the type of building structure, renovation plans, and on-site survey findings, establish a rational calculation model. Conduct calculations on the mechanical properties of the building's structural materials and the actual conditions after structural changes or changes in use function, in accordance with current regulations, to verify the load-bearing capacity of the related building structures and foundations.
4) Structural alterations to buildings should undergo seismic assessment.

5) Conduct a comprehensive assessment of the safety and feasibility of structural and functional changes to the property, provide testing and evaluation conclusions, and propose corresponding measures and recommendations.

Jingzhou Residential Building Structural Functional Renovation Safety Assessment Parameters
1. On-site inspection
Houses tilting, uneven settling, wall cracks, foundation, masonry structural components, wooden structural components, concrete structural components, etc.
2. Off-site inspection
1) In concrete structural component testing, concrete core testing is used to measure concrete strength.
2) In steel structure component inspections, the tensile strength test method is used to measure the tensile strength of steel specimens, while the bending strength test method is employed to assess the bending strength and elastic modulus of steel specimens.
3) Wood Transverse Compressive Strength Test

Building Structure Modification Structural Inspection
Reinforced concrete structure — frame structure inspection
Structural Field Inspection
1) Structural design drawing review
2) Component size inspection, including frame column cross-sectional dimensions, beam cross-sectional dimensions, and floor thickness.
3) Concrete Strength Testing
4) Reinforcement inspection of load-bearing components, including rebar diameter, frame column reinforcement, frame beam reinforcement, and frame beam reinforcement.
5) Inspection of structural and component damage and defects, including detection of deformation in the main structure, damage and defect detection of the main frame structure, and damage and defect detection of other load-bearing components.
