Response of structures to static loads and the calculation of the internal forces in simple structures (beams, frames, truss-beams, arches). Moment-curvature relation (generalized Hooke’s law.)  Equilibrium configuration. Redundancy. Internal forces path. Qualitative moment and shear distributions in redundant structures based on estimated equilibrium configuration. Principles of reinforced concrete. Analysis of  low-redundancy structures (beams, cable-stayed beams, grid of beams, pre-stressed structures…).
