CAEE 436 Reinforced Concrete Design Review Quiz 10 Nov. 9 2018 Name Open book and notes...
1) [Design] A reinforced concrete column is to be sized to carry pure axial compressive load. According to ACI 318, what is the smallest possible cross-sectional area (Ag) that the column can use in design supporting an axial dead load of 200 kips (unfactored) and live load of 400 kips (unfactored). Use fc = 4,000 psi and fy = 60 ksi. Assume pe = 0.08 and ties for transverse reinforcement. Be sure to include the appropriate design factors and use...
Name: Date: Part II: Numerical responses 1. (+35) Design a rectangular reinforced concrete beam (tension steel only) for a simply span of 30 ft. Uniform service loads are 2 kips/ft dead load (included the beam weight) and 3.0 kips/ft live load. The beam is to be not exceed 16 inch wide due to column size. Use fe'=4000psi and fy 60000psi. Sketch your design and calculate Mn for the beam you design. Note: this is an open-end design for you to...
Design a square footing to support an 18 in. square column tied interior column reinforced with 8 #9 bars. The column carries an unfactored axial dead load of 245 kips and an axial live load of 200 kips. The base of the footing is 4.0ft. below final grade and allowable soil pressure is 5 k/ft2 Use ??′ = 3.0 ksi and fy = 60.0 ksi
. Deisgn a reinforced concrete cross-section with unknown dimensions Problem 1 Design the steel reinforcement for the beam shown in Figure 1 that supports its own self-weight, a uninformly distributed dead load, a uniformly distributed live load, and a live point load located at midspan. In your solution, you should select the area of reinforcement, the number and size of reinforcing bars, and the section depth in order to receive full credit. Assume J 5,000 psi, fy 60,000 psi. 16...
Reinforced Concrete Design Please answer it with good write . Problem 1: The reinforced concrete cantilever beam shown is subjected to a concentrated load P- 2 kips, at its free end. Determine the development length of the shown bars using the detailed and simplified methods for the following cases: a) straight bars b) 90 hooks c )180, hooks The column width is 22 inches. Concrete cover is measured from the concrete surface to the center of the reinforcement. fc 4...
Reinforced Concrete Exam 1 CiEn 470, Reinforced Concrete Last Name, First Name Problemt3[40% esign a 24-foot long reinforced concrete beam to support a dead load of 500 lb/ft (including the beam self weight) and a live load of 1,500 lb/ft The architect has requested a beam width of 9 inches. Use 60 ksi steel and S ks concrete. (Assume #3 stirrups) a) D b) Sketch the detailed cross-section of your design c) Analyze your design for safety.
concrete design Design a circular column with spiral reinforcement to resist a service dead load of 350 kips and a service live load of 325 kips. For your design: Use fe'-5 ksi and f, 60 ksi. Utilize an initial reinforcement ratio, Ps 0.03. . Use a clear cover of 1.5 inches. . Limit your design to #8 bars for longitudinal reinforcement. Design both longitudinal and spiral reinforcement. Design a circular column with spiral reinforcement to resist a service dead load...
2. Design a square-tied reinforced concrete column to support the design loads shown below. Assume that the column must be designed with the reinforcement placed around the edges and y = 0.8. Take f.' = 4,000 psi and fy - 60,000 psi. Assume you have to use #9 bars for the longitudinal reinforcement. (35 pts.) P, - 400 kips M. -125 ft-kips
Design a square single column footing to support an 18 inch square interior column reinforced with 8-#10 bars. The column carries an unfactored dead load of 245 Kips that includes weight of soil and weight of footing and an unfactored live load of 20 feet below finished grade. The footing is 10 feet by 10 feet and is 30 inches thick. The allowable soil pressure is 5000 psf, fe' 4000 psi and fy 60000 psi. Concrete used shall be sand...
A reinforced concrete beam with dimensions (300 mm * 800 mm) subjected to a service dead load moment (MD= 500 kN.m) and a service live load moment (ML = 400 kN.m). Design the section as a double reinforced section (the dimensions can't be increased). Place the compression reinforcement at 65 mm from the compression face. Compressive strength of concrete; fc = 28 MPa, yielding stress of reinforcement; fy= 420 MPa. Assume 30 mm to be used in the tension (two...
