Solution:
1. Design a wall footing for the following conditions. Service dead load is 6 kips/ft, service...
2. Design a square spread footing for the following conditions. Service dead load is 350 kips, service live load is 275 kips. Soil density is 130 lb/ftº. Allowable soil pressure is 4500 psf. Column is 18 in. square. Geotechnical analyses have determined the width to be 13 ft. fe' = 3500 psi normal weight concrete, and fy= 60 ksi. The base of the footing is placed 5 ft below the ground surface. Note: you don't need to design the bar...
A (9’x9’x32”) square footing is supporting 230 kips dead load and 130 kips live load from 18-in square column. The allowable bearing soil pressure is 5000 psf. There is no over-burden soil weight. Check if the footing area satisfies the soil bearing pressure requirements. Also, check if the thickness satisfies the shear ( two and one way) requirements. Finally, design the flexural steels each direction. Open book and notes Name a (9%9x32") square footing is supporting 230 kips dead load...
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...
CVE 313- 1- Design a square footing for the interior column shown in the figure. The column carries 2 k 't of uniform live load and 1.5 k/t of uniform dead load (including the self weiht of the structure), the base of the footing is 5 ft below grade, the soil weight is 100 lb/ft', and q," 5000 psf. and concrete unit weight is 150 lb/ (25 points) NOTE: Your design should only include the following (one-way shear, two-way shear,...
HW#10 Given the following column loading and footing information, determine the size of a mat foundation shown below: I 15 Column Information: Column A: Live load = 40 kips, Dead load = 50 kips Column B: Live load = 80 kips, Dead load = 100 kips. Distance between two columns: 15 ft. W soil = 120 psf 24" I CA C. Footing information: Distance from column A to edge of footing: 1 ft. Allowable soil bearing capacity = 3000 psf...
Fall 2017 Assignment # 7 Due Date: Sunday, Jan 07 at the start of class Q. No. 1: Design a footing for a wall which is subjected to a dead load of 14 kips/ft and live load of 10 kips/ft. Geotechnical investigations show that the allowable bearing pressure of oil is 4.5 kips/ft Consider keeping the base of footing at 4 feet below the ground level. Use· =4000 psi and fy = 60,000 psi
Design a rectangular simple supported beam to carry service loads of 1.05 kips/ft of dead load (DL) (self-weight included) and 2.47kip/ft live load (LL) on a span length of 18 ft. The beam is limited to be (due to architectural reasons) 10” wide with an overall depth of 20”. Use f’c= 3,000 psi and fy= 40,000psi. Design the longitudinal reinforcement (flexure design) and the web reinforcement (Stirrups).
