Post-disaster housing quality inspection according to the fire scene combustible ignition point, melting point, deformation, burns, etc., to determine the temperature of the fire, through the fire investigation report, on-site building damage and characteristics, to determine the role of the fire time and scope of action. Post-disaster housing inspection and testing program includes housing suffered from fire, snow, wind, earthquake, explosion, etc., the scope of damage to the structural components of the housing, the degree of damage and residual resistance testing, the scope of application includes the damage to the structural components of the housing need to be assessed after the disaster inspection of the building or structure. On-site inspection includes damage scope, extent, residual resistance, settlement, tilt, cracks, masonry structural components, foundation, wood structural components, concrete structural components, steel structural components, etc.
Post-disaster housing quality testing content:
1. Determine the degree of disaster, such as rainstorm coefficient, fire temperature field and earthquake magnitude and intensity, etc.; according to the degree of damage to the house, the type and number of combustibles, and the presumed scope and scale of the fire.
2、Survey the appearance of the damaged structural components, initially determine the temperature distribution of the components and the degree and extent of damage.
3、Using on-site testing instruments, the damaged components and the corresponding undamaged components for comparative testing.
4, if necessary, on the damaged parts of the damaged members of the material sampling, microscopic testing, to determine the degree of damage to the structural components.
5. Determine the structural mechanics model, carry out structural bearing capacity calculation, and determine the structural reinforcement program.
Post-disaster quality testing process:
1、According to the degree of damage to the house, the type and quantity of combustible materials, and the presumed scope and scale of the fire.
2、Appearance investigation of the damaged structural components, preliminary determination of the temperature distribution of the components and the degree and extent of damage.
3、Using on-site testing instruments, the damaged components and the corresponding undamaged components for comparative testing.
4、If necessary, take samples of the damaged parts of the damaged components, conduct microscopic tests to determine the degree of damage to the structural components.
5. Determine the structural mechanics model of the house, carry out structural bearing capacity calculation, and determine the structural reinforcement program.
