Study On The Influence Of Pouring Construction Sequence Of Concrete On The Support System Of Ultra-high Template Under Confinement

With the gradual development of the industry,some basic problems has been found and solved,formwork support system theory is more and more abundant,experience more rich,the stability and safety of the scaffold itself also gradually improve.But industry insiders in the load calculation of the stability of the high mode of using the instantaneous load,that all loads are not instantaneous and evenly to the template,and not the upper construction load imposed order to consider the influence of ignoring the high formwork under huge eccentric load is the most unfavorable condition.Shenzhen Vanke Yuncheng four project intends to build a business center,in order to show the inside of the building space and show the beautiful architectural effect,the space structure of large span and height,and with the first floor and adduction convex,unique style,in the process of construction,some structures need tall formwork support system,put forward higher requirements on the construction.This paper takes Shenzhen Vanke Yuncheng four super high formwork support system construction example based on the large-scale general finite element analysis software Midas-GEN as research tools,research in different construction schemes of concrete pouring sequence,high formwork system in force components should be the change of stress and strain state of the research on ultra high the top surface of the concrete formwork supporting construction sequence system in unconfined conditions influence the stability of the template structure itself.
