(b) The bridge shown in Fig. Ib has an internal hinge at D. 10kN 30kN 50kN Hinge 10mカカ10m 8m 6m Fig. 1b . Using Muller-Breslau principle, draw qualitative influence lines for shear at mid-point of E and just right of supports C and E (Fig. Ib). If a three axle car is passing through the bridge as shown in Fig. Ib, determine the maxim moment at the mid-point of BC.
Q3. Explain what is meant by “maximum absolute moment and shear in beams”. Your explanation must be based on cantilever beams and simply-supported beams subjected to single and multiple concentrated loads. (15 marks) Given a 3-axle truck with the following loads as shown in Figure Q3, determine the position of the truck that produces the maximum moment on a 24 m simply supported bridge when the train moves on the bridge. You may ignore the weight of the bridge and...
A small rural bridge will have, at most, two cars on it at a
time. Assume it can be modeled as a rigid horizontal beam element
supported by three elastic vertical columns as shown.
Your design condition is two cars each weighing P=40kN
each travelling exactly 20m apart from each other across the
bridge. Find the maximum compressive and tensile forces experienced
by the columns. For now, you can assume the maximum forces will be
experienced when both cars are...
Example 2 Suppose one truck is parked on a bridge as shown in the Figure. The truck weighs 1000 lb which is acting through its center of gravity (CG). The bridge weighs 200 lbs per feet, which is uniformly distributed. We can assume the bridge is rigid. We want to know what will be the reaction forces at the supports of bridge at the two ends 1000 lbe 200 Ib/ft 25 Force? 50 Force? Figure 1
