For the frame shown below, q = 1.1 kN/m and L=8 m. (1) Analyse the frame assuming beam = 21 and column = 1. (2) Determine the deformed shape and BMD of the frame. In BMD, determine (a) relevant values at the "strategic" points; (b) magnitude(s) and location(s) of the local maximum or minimum moment(s); and (c) location of contraflexural point(s).
