A Cascade High Energy Earthquake-Fire Coupling Test System

Abstract

The invention discloses a cascade high-energy earthquake-fire coupling test system, which includes a self-balancing loading system, a lifting furnace system, and a smoke collecting hood system installed on the upper end of the lifting furnace system to collect smoke; the self-balancing loading system includes two The mobile reaction force frame walking on the first track and the high-temperature self-sensing loading beam erected on the top of the two mobile reaction force frames; the lifting furnace system includes a furnace body with a combined furnace body hoisted inside and capable of walking on the second track The installation frame, the upper end of the furnace body installation frame is slidingly connected to two moving beams, the lower end of the moving beam is equipped with a mobile hoist, and the bottom of the mobile hoist is hoisted with operating devices; this system can meet the requirements of different earthquake-fire coupling tests.

Description

technical field [0001] The invention relates to the technical field of fire or earthquake-fire coupling, in particular to a cascade high-energy earthquake-fire coupling test system. Background technique [0002] At present, research on the mechanism and prevention and control of multi-disaster coupling disasters has become a major national demand. Among them, earthquakes and fires are the most frequent coupling disasters, which may lead to major accidents and disasters. At present, the main steps of earthquake-fire coupling test in China are to conduct earthquake simulation shaking table test first, and then move the model to the fire test furnace for fire test after the earthquake simulation shaking table test is completed. [0003] However, there are several problems in the test process: (1) During the process of moving the test model, damage to the model and residual deformation may be caused; (2) The conventional fire test furnace can only be used for the test of compone...

Problems solved by technology

[0003] However, there are several problems in the test process: (1) During the process of moving the test model, damage to the model and residual deformation may be caused; (2) The conventional fire test furnace can only be used for the test of component specimens, and cannot be used for multi-layer frames The test of the overall structure, and the test of a certain layer of the multi-layer frame cannot be carried out; (3) the size of the test furnace is fixed, which limits the size of the test model; (5) The traditional method of applying horizontal and vertical forces at the same time is technically difficult and complicated to operate, and often cannot guarantee that the vertical force is completely loaded vertically; (6) When fire tests need to be carried out in different places, it is impossible to Using the same fume collecting hood system to conduct calorimetric tests at different stations, and using different fume collecting systems may cause large errors in calorimetric results; (7) The traditional fume collecting hood system cannot be vertically lifted
