Design isolated rectangular footing in an excel sheet for a 4.2 m by 2.1 m footing under 1500 kN, with soil capacity 200 kN/m^2, depth, bending moment and shear checks.
This lecture demonstrates how to design an isolated square footing with an Excel sheet, covering 500 by 500 mm column, bearing capacity, footing area, bending moment, shear, and reinforcement.
Design a square pad footing using Excel. Determine footing size, net upward pressure, depth from bending moment, steel area, and perform one-way, punching, and two-way shear checks.
Design a combined rectangular footing using an Excel sheet, calculating loads, bearing capacity, and reinforcement for adjacent columns along a property line, with bending moment and shear checks.
Learn to design a raft footing without beams with an Excel sheet: input data, compute eccentricities, soil pressure, depth criteria, and reinforcement in x and y directions.
Design raft footing using beam and slab type for heavy column loads in low soil bearing conditions, guided by the excel sheet for slab, secondary and longitudinal beam design.
Designs an eccentric footing with uniaxial movement for 600 kN axial load, 200 kN shear, and 100 kNm moment, calculating footing size, depth, steel, and overturning checks.
Designs an eccentric footing for a column at the edge using an excel sheet to determine footing size, loads, and reinforcement, including shear, bearing, and overturning checks.
Design a strap beam footing to reduce eccentricity at a property-line column, determining L1 and L2 for a 6.24 m square footing with strap reinforcement, shear checks, and punching shear.
Design a strap beam footing for eccentric loading using a combined footing approach, detailing transverse and longitudinal reinforcement, shear and bending moment calculations, guided by an Excel design sheet.
This is the footing design excel sheet course through which different elements of footing like isolated footing (rectangular and square), PAD footing, Eccentric footing (when column at the edge of the footing) , Combined footing design , Strap beam footing design, Raft footing design ( without beams or with Beam and Slab) etc. are designed through Excel sheets, The students can use these sheets to design these elements in very less time and with accuracy.
The footing design is very time taking job manually , hence these excel sheet will help students that they can check their design through input their values in pink cells given in the sheets. All the design steps are given like analysis and design of these footings.
The Steps are as under:
1. To find the initial sizes like width , length and depth of the footings.
2. Net pressure from below the soil.
3. To find the Shear Force diagram and Bending Moment Diagram and values.
4. To find the Reinforcement ( Main Tensile) and Distribution Steel.
5. To Check on One Way Shear and Two Way Shear Check.
6. To Check Development Length Check.
7. Detailing Diagram of Design.
Therefore, Every students should try to learn manual concept behind the design of footings through these excel sheets and saves lot of their time.
