Question 2 For the continuous beam with maximum moment capacity Mu shown below, identify all possible collapse mechanisms and find the collapse load for each of them. Which one of the mechanisms you found is the true collapse mechanism? 5 P B 5 P C 4 P 2L 2L 3L 2L 2L 3L Answers: Collapse load for AB opening: P=0.3 Collapse load for BC opening: P2 = 0.33- M L Collapse load for CD opening: P3 = 0.4167 True collapse mechanism @AB opening M L M L
