- A prefabricated structure is used to construct a bus stop. Several forces are applied to this rigid body as shown in the cross section in the Figure below. The acting loads on the cross section are represented by three concentric forces F⃗1 = 60 kN at I, F⃗2 = 10 kN at G, and F⃗3 = 40 kN at Q, and a couple M⃗1 = 250 kNm (clockwise) at H. The distributed load effects from the snow are vertical acting between points N and P on the canopy, and points D and C on the lower slab. The distributed load between N and P increases linearly from 0 to a magnitude equal to w1 = 15 kN/m, while the distributed load from D to C starts with a magnitude w2 = 18 kN/m and decreases linearly to w3 = 10 at G due to the wind effect. The angle α of force F⃗1 with the horizontal line is 25o. F⃗2 is vertical, while F⃗3 is horizontal. Do the following: 1. Find the reduced force-couple system at point E.2.

The beam has recently been strengthened by the addition of two steel plates 205mm deep by 5mm thick which have been bolted to each face of the beam. The beam is simply supported and carries a uniformly distributed load of 6kN/m on a span of 5m. (i) What was the max bending stress in the wooden beam before the addition of the steel plates? (Ignore the self-weight of the beam in your calculations.) (ii) Determine for the strengthened beam the maximum stress in the steel and wood due to flexure. (Assume that the bolts are adequate to ensure composite action and ignore the effect of any bolt holes on the cross section properties. The load was removed during the addition of the steel plates and then reapplied to the new composite beam).
