Bending‐Curvature at Ultimate Limit State (ULS)
This chapter opens with a discussion on the bilinear approximation of the moment‐curvature relationship of reinforced concrete beams. The behavior of a reinforced concrete beam in bending up to the ultimate limit state (ULS) is composed of different complex inelastic stages. First, the chapter starts from a phenomenological approach describing qualitatively the main phenomena involved at the ULS of a reinforced concrete beam. Second, some bending‐curvature's models are analyzed based on both the local constituent behaviors and a global simplified bending‐curvature constitutive law. A bilinear approximation of the complex nonlinear bending‐curvature constitutive law can model the different nonlinear stages with sufficient accuracy. In this chapter, the bending response of a reinforced concrete cantilever beam is theoretically investigated up to the failure. Finally, the buckling and postbuckling behaviors of reinforced concrete softening columns composed of quasi‐brittle materials such as concrete and composite materials are discussed.
