Chapter 18, Problem 6P

The 4-story building shown below has a dead load D = 90 psf, floor live load, L = 110 psf. The roof and floors have the same D and L loads. The length of columns is 24 ft at the ground level and 12 ft for all other floors. The column ends are pins (Kx = Ky = 1.0) and Lx = Ly for all columns. (Use LFRD Method where applicable).1) Determine Pu on interior columns B2-4, B2-1, and side column C1-1  2) Use Table 4-1a (p. 4-12 to 4-24) in AISC to select the lightest W shapes for these columns 3) Use Table 4-4 (p. 4-68 to 4-83) in AISC to select lightest square HSS shape for the columns

Problems 5-1 Stead flow of steam enters a condenser with an enthalpy of 2400 kJ/kg and a velocity of 366 m/sec. the condensate leaves the condenser with an enthalpy of 162kJ/sec and a velocity of 6 m/sec what is the heat transferred to the cooling water per kg steam condensed. (-69198 kJ/kg) 5-2 An air compressor delivers 4.5 kg of air per minute at a pressure of 7 bar and a specific volume of 0.17 m³ /kg. Ambient conditions are pressure 1bar and specific volume 0.86 m³/kg. The initial and final internal energy values for the air are 28 kJ/kg and 110 kJ/kg respectively. Heat rejected to the cooling jacket is 76kJ/kg of air pumped. Neglecting changes in kinetic and potential energies, what is the shaft power required driving the compressor? (14.3kW)

Determine the design resistance to transverse force F,Rd

As a structural engineer, your task is to design an optimum section that has sufficient resistance to the applied loading for the primary beam proposed in Figure 1. A UB in grade S275 steel is required for the unrestraint beam to carry the ultimate loads over the given span. Choose an optimumUB section and justify your selection. You are required to submit a design analysis by considering bending, shear, transverse force, and deflection checking for the selected member based on Eurocode 3 and the assumption of support condition and loading must be clearly stated.

Why is it important to establish logical relationships between tasks when developing a construction schedule?

For the gravity concrete dam shown in the figure, the following data are available: - Unit weight of concrete (Yeone) = 2.4 ton/m³ Neglect( Wave pressure, silt pressure, ice force and earth quake force) -0.65, (Ywater) 1 ton/m³ Find factor of safety against sliding and overturning (F.Said & F.Sover), If heel and toe stresses (Pais & Pmas) are 57.17ton/m2 and 84.53 ton/m² respectively. w.s.l 83m 10m 80m 8m Solve on paper step by step with sketch

Why is proper planning important when developing a baseline construction project schedule?

Determine the minimum possible surface area of a secondary clarifier treating activated sludge with a design influent flow rate (Q) of 1,000 m³/d, a return activated sludge (RAS) recycling ratio of 25%, and a mixed liquor total suspended solids (MLSS) concentration of 4,000 mg/L, if the overflow rate must be less than 33 m/d and the solids loading rate must be less than 250 kg/m²/d. Express your answer in m² and round up to the next integer.
