Chapter 15, Problem 12RQ

A cantilever beam 12 ft long supports a uniform service superimposed deadload of 1 kip/ft, and a concentrated service live load of 14 kip at the free end. Theconcrete compressive strength is 4 ksi, and the steel yield strength is 60 ksi. Thebeam section at the support is shown. Find the adequacy of the section inresisting bending moment at the support.

A simply supported beam for a building interior with 18 ft span has a cross section of 12 in width and 21 in overall depth. The beam is made with 5 ksi compressive strength concrete and 60 ksi reinforcing steel. The beam supports a uniform service superimposed dead load of 1.6 kip/ft, and a uniform service live load of 80 psf throughout the span. The beams are laterally spaced 20 ft apart c/c. Design this beam and show in a sketch.

The dam presented below is 180 m long (in the direction perpendicular to the plane of the cross-section). For the water elevations given on the drawing: a) Construct the flow net (minimum number of equipotential lines should be 10), b) Calculate the rate of seepage for the entire dam, c) Find the total uplift force on the dam (ignore barriers), and d) Estimate the hydraulic gradient at points A, B, and D. Recommended to use a spreadsheet to include all equations for calculations of potentials.

Using A36 steel select the lightest equal leg single angle member to resist a factored (LRFD) tensile load Pu = 167 kips. The member will be connected through one leg with one line of three 3/4-in Ø bolts spaced at 3 in between centers as shown. The edge distances Leh = Lev = 1.5 in.  Use LRFD Method Use U from Table D3.1, Case 8. See attached (D3.1 Case 8, Shear Strength of Bolts, Table 1-7 Dimensions of Angles).

The system in Fig. consists of 1200 m of 5 cm cast-iron pipe e=0.26mm, two 45° and four 90° elbows, a globe valve, and a sharp exit into a reservoir. If the elevation at point 1 is 400 m, what gage pressure is required at point 1 to deliver 0.005 m3/s of water into the reservoir?
