a) A three span continuous beam has spans of 27, 30, and 27 feet. The beams support one-way slabs, 6 inches thick that span 20 feet center to center. Assume that the beams are 16 inches wide and 24 inches deep. Determine the dead load in pounds per linear foot for the beams, from the concrete structure alone.
b) The floor beams support ceiling, ductwork, and lighting fixtures weighing a total of 8 psf, ceramic floor tile weighing 16 psf, and partitions equal to a uniform dead load of 20 psf. Determine the total dead load.
c) If the building is to be used for offices, what is the specified live load?
d) If the live load to the interior beams may be reduced, what is the reduced live load for the 27 and 30 foot spans, respectively?
A hawk flying at 2 m/s at an altitude of 45 m accidentally drops its prey. The parabolic trajectory of the falling prey is described by the equation below until it hits the ground, where y is its height above the ground and x is its horizontal dis..
calculate the moment of inertia for the Milkyway. Assume it to be a disk.
Assuming that the CPI (82-84) for March 2013 is 232.773, and your starting salary is $55,000. How much would your starting salary have been in 1983 (assume CPI=100).
Would you expect to find the Tapeats Sandstone on top of the Great Unconformity in all places in the Grand Canyon? Why, or why not?
Calculate the force (in Kn) a punch press must exert if it is to punch out a large washer from a strip of 5-mm thick sheet steel with an ultimate shear strength of 400 MPa. The washer dimensions are as follows: hole diameter is 27 mm. outside diam..
The distance covered by an aerial photograph is determined by both the focal length of the camera and the tilt of the camera. Although the tilt is usually small, both archaeological and Canadian photographs often use larger tilts.
Draw a plan of a typical strip mine showing all operational features and equipment and why is the working slope of an open pit usually much flatter than the final slope?
determine the transformed moment of inertia for the beam using steel as the reference material. Express your answer in in^4 to the nearest 0.1 in^4.
The maximum vertical load and horizontal load have been identified and shown in the figure. Under this loading condition, you are asked to determine the horizontal deflection of joint C.
The undeformed length of the spring is l. Knowing that the collar is released from rest at x = and neglecting friction between the collar and the horizontal rod, determine the magnitude of the velocity of the collar as it passes through point C.
A community has three major sources of power supply: electricity, gas and oil. Let E, G and O denote events of shortages of each of these power sources, respectively. Their probabilities are estimated to be 0.15, 0.10 and 0.20 respectively.
Find the swell for a soil which weighs 1600kg/m in bank and 1300kg/m3 in bank and 1300kg/m3 Loose and what is the shrinkage factor for a mass of soil that takes up 1.5m3 in bank and reduces down to 1.2m3 after compaction
