Question
Draw the influence lines for the reactions Ax and Ay at the left pin support
and the bending moment at section 1 located at the face of column AB. If a uniform live
of 0.8 kips/ft is applied on top of the frame, compare the bending moments at section 1 if
the live load is only applied on top of the entire span BC, CD, and BD. Discussion the
variations and which is the critical loading scenario.
Note: Construct the influence lines of each loaded structure by equilibrium method not muller-breslau's principle. Use the ordinates of the influence lines to calculated the load for the required member support or section.
