Study on the Influence of Stress,Stability and Carbon Emission of Air Conditioning Pipe in High-rise Building Based on FLAC3D Software Simulation
In order to optimize the support structure of air conditioning pipe in high-rise buildings,the influence of pipe diameter,wall thick-ness,flange installation position and horizontal elbow Angle on pipe stress was simulated and analyzed by using FLAC3D finite element soft-ware.The simulation results show that the increase of pipe diameter will lead to the increase of primary stress,and the increase of wall thick-ness can effectively reduce the stress.At the same time,the optimization of flange position and the adjustment of elbow Angle also help to re-duce stress concentration.When the flange is installed 3 m away from the middle of the pipe,the primary stress ratio and deflection are only 7.35%and 0.43 mm.Based on this,an optimization scheme for the support structure design under large pipe diameter and complex load con-ditions is proposed to further improve the stress distribution of the pipeline.
