A Simply supported rectangular, tension-reinforced beam is to be designed for dead load of 0.75 k/ft plus self weight and service live load of 2.0 k/ft, with a 30 -ft simple span. Material strength will be fy = 60 ksi and fc = 5 ksi for steel and normal weight concrete respectively.

Start the design of the beam dimensions using the rules of thumbs in class. The total beam depth, h, must not exceed twice the width.

Calculate the required beam dimensions and tensile steel requirement (As required) to carry the Maximum moment found at mid span. Start with a steel ratio of half of "usable rho" in Table 27.2 in the text. Use ACI load factors and strength reduction factors. The effective depth (d) may be assumed at 3 inches less than the total depth (h).

Draw a sketch clearly showing spacing, cover, and bar locations.

1. What three methods meet OSHA requirements for protecting workers in an excavation when worker protection against cave-in is required?

2. Discuss three (3) common deficiencies in concrete construction. What are viable precautions that can be taken to prevent these deficiencies?

An electrostatic precipitator is to be designed to collect dust from a pulverized coal boiler with an actual flow of 100 m3/s. The effective migration velocity for the flyash is anticipated to be 0.08 m/s. The design gas flow velocity is 1.2 m/s, the plate height is 10 m, and the plate-toplate spacing (2s) is 0.25 m.

a. Determine the number of ducts required to accommodate the flow [-].

b. For an efficiency of 99%, determine the required plate length [m

What is the Terrain Category in the Middle of Brisbane, QLD Australia and Port Headland, WA, Australia? Is it Terrain Category 1, 2, 3 or 4? I need it for my reference in getting the Wind Speed Vsit.

Thirty-six piles, 0.6 m in diameter, are spread at 2.4 m centres in a 6 x 6 group. The piles extend between depths of 3 m and 18 m in a layer of stiff clay 28 m thick, overlying rock. The undrained shear strength of the clay at a depth of 18 m is 145 KN/m² and the average value over the pile length is 105 KN/m². The following parameters have also been determined for the clay: α = 0.4, A = 0.28, E_u = 65 MN/m² and m_v = 0.08 m²/MN. If the pile group carries a load of 21 MN, determine the load factor and the total settlement.

Consider a double-pane window of size 48.56×73.55 cm. The window is framed in aluminum. If the maximum and minimum outside temperatures are 30.28 and -32.21 °C, respectively, how much gap do you need to allow between the glass panes and the frame?
