WebbRequired footing area of A = 99/2.58=38.4 ft2. Use 6’ by 6.5’ footing, area = 39 ft2. Reaction at footing B = 100+80-9=171 kips Required footing area = 171/2.58=66.3 ft2. Use 8’ by 8.5’ footing, A = 68 ft2. Structural analysis of strap footing Procedures Calculate factored column loads, Pua & Pub Calculate factored eccentric moment Mu = Pua*e WebbThe following plate load test apparatus is necessary for performing the test. A steel plate is at least 300 mm square and 6 mm thick. A hydraulic jack with a capacity of at least 1.5 times the anticipated test load. A set of steel shims, at least 6 mm thick. A dial gauge, with a range of 0-250 mm and an accuracy of 0.02 mm. the chocolate cobweb charlotte armstrong

Proportioning of Footing - YouTube

http://www.civilology.com/trapezoidal-footing-formula/ WebbThe combined footing should be provided in following circumstances: (i) when the columns are very near to each other so that their footings overlap, (ii) when the bearing capacity of soil is less, requiring more area under individual footing, (iii) when the end column is near a property line, so that its footing cannot be spread in that direction. square or a round footing to resist a specific angle of tilt, a, is determined by the following: B3 = 4320(F) (M/α) ([1 - M2]/E s) (square footing) (Eq. 5) D3 = 6034(F) (M/α) ([1 - M2]/E s) (round footing) (Eq. 6) where: B, D = size and diameter of footing, respectively, feet F = factor of safety (generally use 2.0) the chocolate claim whitehorse
