Earthquake engineering

Evaluate the overstrength, Rmech, due to redistribution of forces in the moment frame shown below. Assume that all members are elastic-perfectly-plastic with the plastic moment capacity shown in the figure. You may assume that for the initial elastic force distribution, the inflection point for all members is located at the mid-point between the ends of the members, and that the controlling mechanism involves yielding of the beams and the base of the columns, i.e., strong-column-weak-beam mechanism. Ignore the size of the joints.earthquake.png

The axial load and end moment (also equal to the maximum moment in the column) are given separately for the different load cases (i.e., dead load, roof live load, and lateral wind load). All vertical loads are symmetrically placed and contribute only to the Mnt moments (i.e.,...
