| Abstract: | Transfer storey itself is studied more than supporting system in constructing it. This paper bases on an actual project to study scaffold supporting system of thick reinforced concrete slab, which transfers loads of superstructure to the lower frame. Through measuring the stresses in the slabs and forces of supporting bars on the spot, the characteristic curve of regularity of developing of concrete strength and unloading of steel pipe supporting are acquired. Analyzing model is set up in the light of finite element method. During analyzing with FEM, contribution of concrete-filled tube to the stiffness of supporting system is included, while Young's modulus and strength of concrete evolving with various ages are considered. Contrasting the results with FEM with data from measuring, the same conclusions are arrived at. Based on this, Scaffold supporting system of top floor of basement is optimized and some constructive suggestions for the actual project are provided. | |
