Özyegin University Department of Civil Engineering 2021-2022 Spring CE 412 Plastic Analysis & Design HW #3 Due date: 18.04.2022 1. A fixed-base rectangular portal frame is of height Land span 21, and is of uniform cross-section throughout, with plastic moment Mp. The frame carries a horizontal load Happlied at the top of one of the columns and also a vertical V at the center of the beam. Find the value of W which would cause collapse for the following pairs of values of H and V, and in each case determine the bending moment distribution at collapse. a) HOW V=W b) H=W V=2W c) HEW V=3W 2. 12P D 8 с A E Xe Xe te X et a) Use the mechanism method to find the collapse load Pc b) Check to see if a statically admissible solution exists for the value of the collapse load. For span ABCD, M=3Mp is the max moment, and For span DEF, M=Mp is the max moment. 3. Determine the failure mechanism and the ultimate load of the given continuous beam below. Use step-by step-method.
