Simulation Calculation of the Collapse Process of High-Rise Steel Structure Energy-Forming Cutting Blasting Demolition

Abstract

The high-rise steel structure building (structure) is a relatively special structure. Due to its high height characteristics and the overall structure height and narrowness, there is still no unified method for this type of demolition. This paper is aimed at studying the simulation of the demolition of high-rise steel structures by blasting through computer video images. For this reason, this paper proposes a simulation of its specific blasting demolition work based on LS-DYNA software. Through an update to its core algorithm, it is more suitable for the simulation of this type of structure and simultaneously carried out simulation experiment research on the improved results. The experimental results of this paper show that the LS-DYNA software after the algorithm update is more referential to the simulation results of the simulation structure of high-rise steel structures. The simulation structure can increase the similarity to 97% in the actual demolition work, and the comparison probability of risks is also increased by nearly 31%. It can greatly improve the demolition problem of this kind of high-rise steel structure building (structure).
