WebA portal frame with pinned bases has a single degree of indeterminacy. Therefore, two hinges are required to create a mechanism. The four hinges shown in Figure 3.1 only … As the plastic moment capacity is reached, the section can rotate freely i.e. it behaves like a hinge. This is termed a plastic hinge which is the basis for plastic analysis. At the plastic hinge, stresses remain constant, but strains and rotations can increase. Plastic hinge mechanism for different types of beams are shown … See more The actual behavior of ductile materials such as mild steel which is represented through the stress-strain curve is shown in Fig.1. it is noted that the material can sustain strains far in … See more
