appreciate if you can show your working steps.
Remarks: The dead load (1200 lb/ft) and live load (500 lb/ft) given in Problem #02 comes from the loadings on the slab. It DOES NOT include the self-weight of the beam. You need to use wc-150 Ib/ft to compute the self-weight of beam and add it to the dead load. However, without b and h, you DO NOT know the self-weight of beam at the beginning. Therefore, for questiona ), you need to make an initial assumption of beam size. With th

2. A continuous concrete floor system consists of parallel beams spaced 8' on centers and spanning 25' between supports. The 4" thick slab is cast monolithically with the beam webs which have width, b 14 in. and total depth h 28 in. (measured from top of slab). Each T- beam must carry a dead load of 55 psf (the slab weight+ flooring) and service live load of 225 psf in addition to its own weight. Material properties are fe-4 ksi...

A rectangular, tension-reinforced beam is to be designed for dead load of 500 Ib/ft plus self weight and service live load of 1200 Ib/ft, with a 22 ft simple span. Material strengths will be fy 60 ksi and J 16 in. Calculate the required beam width and tensile steel requirement, using a reinforcement ratio of 0.60po.o0s. Use ACI load factors and strength reduction factors. The effective depth may be assumed to be 2.5 in. less than the total depth steel...

4.1 The precast concrete beam shown below is subjected to a live load of 1300 lb/ft and a superimposed dead load of 520 lb/ft in addition to its self-weight. Design the beams as a rectangular section. Assume interior beam, ¾" MAS, #4 stirrups, ?? ′ = 5,000 ???, normalweight, ?? = 60,000 ??? (use only #6 or #7 bars for reinforcement). Span- 20-ft

1. T-Beams are used to support a floor in an industrial building. The floor is used for product storage so it must be designed for a heavy 600 psf. The floor must also support a superimposed dead load of 20 psf (in addition to the self-weight of the beams and slab. The layout of the beams and slabs is shown below. The beams span 30.0% and are spaced at 4.0” center to center. The slab is 3” thick. The concrete...

Design a reinforced concrete beam that has a rectangular cross section with a width b = 24 in. The depth h is limited by architectural reasons to 16 in. It has to carry a factored moment Mu = 360 kip- ft. including the self-weight. The design should satisfy ACI 318 for tension controlled members. Use Grade 60 steel and a specified concrete compressive strength = 4,000 psi. Determine the flexural reinforcement for the beam, and use compression steel if needed....
