2) The flooring system shown is composed of slab panels measuring 20 X 25 ft in plan, supported by shallow column-line beams, as shown in the figure. The slab is pre-cast and resting on the beams. The panels carry a service live load of 144 psf in addition to the self-weight of the floor. a) Calculate the factored load on beam CD as per the tributary area shown. Assume a slab thickness of 7 in and the density of the concrete used to be 150 pcf. Use the load combinations from the ASCE 7-10 load combinations for Strength Design (2.3.2). b) Sketch the bending moment diagram (BMD) for the beam using the factored load calculated in step (a). c) Calculate Mu for the trapezoidal load distribution. d) Design a reinforced concrete beam using a rectangular section to carry the Mu calculated in step (c). You can use design guides, but show clear steps. Use concrete with fc'=4000 psi and steel with fy = 60000 psi.
1. (e) One of the limitations of extending axis translation technique for measuring negative pore water pressure using null type pressure plate is: (i)Air diffusion occurs through the ceramic disk when the axis translation test is performed for a long time period. (ii) Water losses from specimen when the test is performed for a long time period. (iii) Secondary consolidation arises when test is performed for a long period of time (iv) All the above (a, b and c) (v) None of the above The ceramic disk used in the null pressure plate apparatus does not allow the air to flow; however, free flow water is possible. Explain the mechanism associated with this behavior. If the purpose of ceramic disk is not to allow the air out from it; how can the air come out from the specimen? What will be the impact of such a phenomenon?
