STUDY ON EFFECT OF CONSTITUTION FACTORS FOR SUPPORTING SYSTEM FOR TALL AND LARGE FORMWORK

On the base of the result that other people study the fastener-style steel pipe scaffold and supporting structure for formwork, the paper constructs the model by investigating the spot and making use of SAP2000 finite element analysis software, and analyses the mechanism deeply that how the constitution factors effect the stability bearing capacity when the physical dimension is unchanged. The constitution factors of the supporting structure for tall and large formwork include longitudinal distance, departure, step length, height of the floor members, length of upright bars extruding from top and distance of bridging in horizontal planes. Ac- cording to the analyzing of the calculating result, the paper puts forward some suggestion and problems about the supporting structure for tall and large formwork during the design and the construction, which the designers and the constructors can refer to.
