Design and detecting analysis of high-formwork system of large-span and deep beam in Yangtze-Crossing Campaign Memorial

摘要

With the large-scale construction and the increase of high-rise and large space buildings in our country, high-formwork system as the support system of girder and slab was widely applied to engineering. As the design theory of high-formwork system is not mature enough and over-reliance on past construction experience when it's under construction, the security of high-formwork system can not be fully guaranteed, which caused numerous high-formwork collapse accidents in recent years. Based on design, numerical simulation and on-site stress detecting analysis of high-formwork system of large-span and deep beam in Yangtze-Crossing Campaign Memorial, the basic situation of stress distribution in bars of high-formwork system was illustrated in this project, which provided reference for scaffold's optimal design and construction in similar projects.
