Research On Optimization Method Based On BIM-MIDAS Super High-rise Scaffolding Structure

Super high-rise scaffolds are complex and time-varying under the action of wind loads,and their safety analysis has traditionally been a focus of attention.Resulting from the instability of the rods and improper construction measures,scaffolding collapses occur from time to time,causing undesirable social impacts.From the whole process of structural design and construction process simulation,the design optimization of the super high-rise scaffolding can ensure that the Structure is improved in terms of steel consumption,structural stress,and construction collision.This dissertation is mainly based on BIM-MIDAS software combined with ANSYS to study the optimization method of super high-rise scaffold Structure,and mainly carries out the following works:(1)Based on Revit Structure modeling principles of BIM core modeling software,a model of super high-rise scaffolding was created using a model of a railing family,realizing rapid design method for super high-rise scaffolding model.(2)Secondary development based on Revit Structure's application program interface solves Revit Structure and MIDAS Gen data exchange issues.(3)Stress analysis of Super high-rise hydraulic climbing formwork scaffold by Midas Gen,it is found that the maximum stress of the frame body is distributed on the bearing platform in three kinds of most unfavorable conditions,the maximum deformation is located at the top of the frame body,the influence of wind load on frame body is more significant than that of live load.(4)Based on the stress of super high rise scaffolding,the structure optimization of scaffold is carried out by using Ansys Workbench optimization method,after optimization,the total weight of the bearing platform is reduced by 13.9% and the maximum stress is reduced from 149.2MPa to 115.5MPa,effectively reducing the amount of material used and stress concentration.(5)Construction simulation of Super high-rise hydraulic climbing formwork scaffold,on the one hand,check whether there is a coincidence in the spatial positionbetween the super-high-rise main body model and the optimized structure scaffolding model;On the other hand,the construction process,construction period,etc.are optimized in the three-dimensional visual state,after the optimization,the construction period is 8 days ahead of schedule.
