| Abstract: | The cuplock steel tubular scaffold is widely used in the construction of cast-in-situ bridges. By research into loading conditions, together with practical engineering, applied finite-element analysis software of MIDAS/Civil, we establish three-dimensional space model, calculate the carrying capacity, stability and capacity of foundation, providing technical help to the construction process and referenced designing and constructing experience of this kind of framework. |
