Reinforced Concrete Design Problems 1 through 4 are based on the following frame

Question

Reinforced Concrete Design Problems 1 through 4 are based on the following frame: As shown in Figure 1, a reinforced concrete frame consists of a rectangular beam, two square columns, and two footings. Assume the connections between the beam and column, and the column and footing are pin connections, i.e., the beam can be designed as simply-supported beam with aspan efe, the beam ean be desiunesd as simply-supporied beam with a span of 25 ft, and the columns are subjected to axial load with a design height of 8 ft. Material strength are f-60ksi and fe-4,000 psi. The beam is to carry a distributed dead load of 1.0 kips/ft including its own weight and live load of 1.6 k/ft. DL-1.0 kips/ft LL-1.6 kips/ft 25' 8' 6 6' Figure 1

Explanation / Answer

CONCLUSION:-

1)

IMMIADIATE DEAD LOAD DEFLECTION = 0.1210 inch

2) (a)

IMMIADIATE TOTAL LOAD DEFLECTION = 0.3146 inch

(b)

IMMIADIATE LIVE LOAD DEFLECTION = 0.1936 inch

3)

COMPARE WITH MAXIMUM DEFLECTION

a)

FINAL DEFLECION=1.2 inch

b)

DELECTION=MINIMUM OF 0.857 inch TO 1 inch

MINIMUM IS 0.857 inch

ALL VALUES OF DEFLECTION LESS THAN 0.857 inch

SO, WE CAN SAY STRUCTURE IS SAFE

ALL CALCULATIONS REGARDING THIS ARE SHOWN IN THE ABOVE IMAGES.
