Portal frame plastic hinge
Web5.6.4 Application to Portal Frames. A portal frame usually involves high degrees of indeterminacy. Therefore, there are always a large number of partial and complete … WebThe members of the rectangular portal frame have uniform cross-sections. It is required to determine the plastic moment on three possible modes of failure. Use a load factor of 2. Which of the following most nearly gives the plastic moment Mp through the formation of plastic hinges at B, and D (sidesway mechanism), in kN.m?
