a. Determine the load from the floor beam, B, that is being supported at the middle of beam A. The floor that it supports has a weight of 0.4 kN/m2; an area 2.5 metres by 6 metres is being carried by the floor beam, half of which is being transferred into the steel beam A. Your answer should be in kN.
b. Considering the following information, determine the theoretical deflection of the steel beam A due to these loads. (Calculate the deflections due to each of the loads separately)
K = 5/384 for a uniformly distributed load; 1/48 for a point load at mid-span
The span of the beam is 5 metres
The beam is a 180UB16.1for which the moment of inertia is Ixx = 10.6 x 106 mm4 and E for steel is 210 x 103 MP
c. Considering that the theoretical deflection exceeds the recommended maximum of span/360 for support of a brittle partition wall, comment on your answer
1. The two steel columns in the previous question are to be replaced with timber posts. They carry a combined total dead load from beam, floor, walls and roof of 40 kN each. A post measuring 100 mm x 100 mm square is to be used. Calculate the compressive stress that would be experienced in the timber and comment on other issues that need to be considered in assessing the appropriateness of this substitution.
2. Explain how a lateral restraint to a column increases its load-carrying capacity, and why a beam might require lateral restraint. Give 2 typical examples of lateral restraints to a beam, and one to a column, in domestic construction.
