Problems solved by technology
At present, there are many studies on the resistance to progressive collapse of steel frames, mainly through improving the compression arch mechanism and catenary mechanism to improve the collapse resistance of the structure, but rarely through enhancing the fasting mechanism of the overall structure to improve the collapse resistance of the structure
Moreover, after the failed column is removed, the remaining structure mainly resists the external load through the failed layer structure, and the joint

The invention discloses a reinforced structure system for preventing continuous collapse of a steel-frame structure by using filler plates. The system comprises a plurality of steel-frame columns andsteel-frame failure columns, wherein the steel-frame columns are located on the two sides of the steel-frame failure columns, the adjacent steel-frame columns are connected with the steel-frame failure columns through a plurality of steel-frame beams, and the steel-frame beams are distributed from top to bottom in sequence. The filler plates are fixedly arranged at the four corners of the area defined by the adjacent steel-frame beams on the upper side, the steel-frame columns at the two ends of the steel-frame beams and the steel-frame failure columns respectively. The structure system can effectively improve the anti-collapse capacity of the structure.
Description
technical field [0001] The invention relates to a reinforced structure system, in particular to a reinforced structure system which utilizes an inner filling plate to prevent continuous collapse of a steel frame structure. Background technique [0002] The local damage of the structure caused by the unexpected load, and the chain reaction spreads to other parts of the structure, resulting in damage that is disproportionate to the initial damage range of the structure, and even causes the large-scale collapse of the building to be called the progressive collapse of the structure. The characteristics of proportional collapse are often accompanied by serious loss of life and property, and bring great negative impact on society. In recent years, incidents of damage to building structures due to continuous collapses have occurred from time to time. Therefore, how to prevent the progressive collapse of the structure due to local damage, or improve the collapse resistance of the s...
