Analysis of the MechanicalPerformance of a Single Piece of Formwork Support
A new type of cantilevered formwork support was designed to solve the requirements of under-bridge passage or river crossing that need to be met during the construction of steel-mixed combination bridges.Based on the ABAQUS finite element software,the new formwork support system wing part was ana-lyzed,and the force performance of the single-piece support under construction load was studied,and the support was optimized according to the analysis results.The results show that the new formwork supports are all in elastic stage under construction load,and the stress performance is good.The optimization of formwork support for the flange part is carried out by increasing the height of vertical rod and increasing the height of top horizontal rod section,and the stress and deformation of the support are 78％and 35％of those before optimization,which satisfy the specification requirements,and the optimization effect is obvious.
