Abstract： By adjusting the mechanical parameters，the collsion analysis between the tower and the surrounding buildings in the tower collapse operation iscompleted，butthe propertiesof the nonlinear elementsareignored，resulting in poor analysis results.In thisregard，areal-time dynamiccolision risk simulation analysis between the tower and the surrounding buildings in the tower collapse operation was proposed. Combined with the mass matrix and displacement matrix，the dynamic modeling of thenonlinear structure was carriedout，and the finite elastic element was introduced to characterize the nonlinear structural properties.Combined with the linear correlation between collisionriskand quantification results，two risk indicators of congestionandproximitywere constructed.Thecollision risk value was solvedby grading thecollsion risk index and mapping it to five diffrent warning levels.The experimental results showed thatthe ideal fiting coeficient of the analysis results was high and the analysis accuracy was relatively good when the real - time dynamic collision risk was simulated and analyzed.
