WebSteel sections used in portal frame structures are usually specified in grade S355 steel. In plastically designed portal frames, Class 1 plastic sections must be used at hinge positions that rotate, Class 2 compact sections … 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 something to believe in crossword
