A two-dimensional beam structure or frame (ABCD, shown below) has a concentrated load, P, acting on Point D. You can assume that the connections at B and C have sufficient strength to react the applied load and that loads and moments are transferred between the beams. You can assume that the members have a constant cross-section and that El-constant. B A 2m y L. C P-3kN D 2m In order to evaluate the design you must: (a) Sketch the deformed shape of the frame, solve the reaction forces and construct the bending moment diagram for the frame. (b) Use any method to determine the vertical deflection at Point D. Ensure that you clearly explain your approach and show your final answer. Clearly state any assumptions made. (c) If the bending rigidity, El, of the frame between Point B and Point C was doubled. What effect would this have on the resulting horizontal deflection at point D. Ensure that your answer is supported by suitable reasoning, calculations and/or sketches.

1.) Determine the force in each member (and identify whether it is compression or tension) of the truss supporting a floor deck as shown. The deck is simply supported on floor beams which, in turn, are connected to the joints of the truss. Thus, the uniformly distributed loading on the deck is transmitted by the floor beams as concentrated loads to the top joins of the truss.
