ABSTRACT
Due to the complex connection of components and significant initial defects in the formwork structure, the utilization of a direct analysis method to design the formwork structure can effectively address the shortcomings of traditional first-order linear design methods in formwork design standards. Taking a practical engineering project as an example, a direct analysis method for the construction of a SCP structure was proposed. Based on its design results, a comparative analysis with the traditional first-order linear design method was conducted to clarify the influence of considering initial defects and second-order effects on support reaction force, deformation, and stress ratio. This provided a reference basis for the design of SCP structures. Based on the results, cross-sectional optimization was carried out on the key components of the SCP structure. Following optimization, the stress ratio distribution of the structure was found to be more reasonable, and a 25.63% reduction in steel consumption was achieved, thus demonstrating the feasibility of the direct analysis method in the design and optimization of the SCP structure.
