Problem-4. For the beam shown, draw the influence lines for the shear and bending moment at point C and the shears just to the left and just to the right of support D. B C D E F -4 m- -3 m- -4 m- -6 m- -5 m-

For the girder shown below, draw the influence lines for shear in panel CD and the bending moment at point D. Then, determine the moment of point D due to the live load group and a uniformly distributed load of 50 kN/m if the system of loads will be moved to the right.

Draw the influence lines,   a) the shear at section 1-1,   b) the moment at section 1-1.   Show complete solutions

(a) Draw the influence line for the positive moment at B (Figure P12.53). (b) If the beam carries a uniformly distributed live load of 2 kips/ft that can act on all or part of each span as well as a concentrated live load of 20 kips that can act anywhere, compute the maximum moment at B. (c) Determine the maximum value of live load moment at B produced by the set of wheel loads.

Daw the influence line for the shear in panel AB and CD and the bending moment at D of the girder with the floor system shown bekow

Draw the influence lines, a) the shear at section 1-1, b) the moment at section 1-1. Please show complete solutions.

For the beam shown, it carries a series of concentrated loads moving from left to right. Using influence lines for the beams compute the following: a) max ordinate of the influence line to obtain the max positive moment at point B. b) position of point 1 (145kN) from point A to produce maximum positive moment at B. c) Maximum positive moment at B due to the series of concentrated loads.

Draw the influence lines for forces in bars AL and KJ. Using the influencelines, determine the maximum live load force (consider both tension and compression)produced by the 54-kip truck as it transverses the bridge, which consists of two trusses.Assume  the  truck moves  along  the  center  of  the  roadway  so  that one-half  of the truckroad is carried by each truss. Assume the truck can travel in either direction. 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.
