Factory load testing is a part of the stability inspection (safety factor, applicability, and reliability) of buildings, which involves research, on-site inspections, and structural analysis calculations to assess the safety coefficient of the building and determine its reliability.
Factory load capacity inspections are generally applicable to buildings that have identified safety risks, risk situations, or other needs for safety enhancement evaluations. While building safety inspections do not encompass various flood disasters that could potentially cause damage to buildings, it is still necessary to conduct a safety assessment of the building itself when risk indicators are observed during post-disaster reconstruction.
The specific content of the factory building load testing includes the investigation of the building's application history and structural management system, detection of construction errors and defects, measurement of building deformation, assessment of the building's condition, identification of the fundamental causes of building damage, testing of the characteristics of building structural materials, structural calculations, evaluation of the building's safety coefficient, and recommendations for structural reinforcement solutions, encompassing seven main aspects.
What must be understood about the load-bearing capacity test of the factory building? The general process for evaluating the load-bearing capacity of concrete floors in factory buildings is typically as follows:
1. The development of factory construction, application, and renovation, including architectural design styles and structural management systems.
2. Create architectural floor plans, engineering architectural floor plans, building facades, cross-sections, structural floor plans, and key precast component cross-sections.
3. Conduct sampling tests on the characteristics of the raw materials for the load-bearing structure of the sampling facility, ensuring the total number and locations of the prefabricated components meet the relevant specification requirements. The sampling locations should include symbolic destruction of prefabricated components.
4. Assess the structural integrity, interior renovation, and machinery condition, as well as analyze the causes of damage.
5. Inspecting the factory for any tilt and uneven ground settlement.
6. Based on the assessment of the factory building's physical performance, a scientifically rational calculation model is created according to the current bearing capacity, usage status, and factory building structural management system, to verify the current bearing capacity of the factory building.
7. Based on the evaluation of the physical performance of the factory building structure, and considering the current bearing capacity and the factory building structural management system, utilizing the characteristics of local large earthquakes' spectral response, we have established a scientifically and reasonably designed calculation model. This model assesses the current seismic resistance working capacity of the building and verifies the structural strategies for seismic resistance.
8. Inspect the management status of the building machinery and equipment.
