The optimal design of reinforced concrete folded plate structures under multiple loading conditions is presented. The design variables include geometrical quantities, like the thickness, dimensions of the structural members (plates), and topological parameters, which define the locations and the connectivity of such elements. The structural analysis required during the design process is performed by using the classical finite strip method and complex harmonic coupled finite strip method for the solution of the corresponding geometric nonlinear design problem. Some applications to the optimal design of prismatic folded plates show the effectiveness of the proposed procedures.

Spline Finite Strip

A layered spline finite strip model for the analysis of reinforced concrete slab bridges is presented in this paper. The natural coordinates ξ–η are adopted to make the method suitable for arbitrary curved slab bridges. A material model based on orthotropic nonlinear elasticity is employed to represent the property of plain concrete. Reinforcement is modeled as an elastoplastic strain-hardening material. The Newton–Raphson method and relaxation techniques are used to solve the nonlinear stiffness equation. Numerical examples are provided to demonstrate the efficiency and accuracy of the model. Key words: spline finite strip method, curved slab bridges, reinforced concrete, nonlinear analysis.
