Design a wall footing to support a 30cm − wide reinforced

concrete wall with a dead load DL =293 KN/m and a live load

LL = 218 KN/m. The bottom of the footing is to be 1. 2m below the

final grade, the soil weighs 16 KN m3 ⁄ , the allowable soil

pressure, qa = 192 KN m2 ⁄ , and there is no appreciable sulfur

content in the soil. fy = 420MPa and fc′ = 21MPa, normal-

weight reinforced concrete with density equal to 23. 5 KN m3 ⁄ .

A wall footing is to support a 400 mm wide reinforced concrete wall with a dead load of 270 KN/m and a live load of 210 KN/m. The bottom of the footing is 1.50 m below the final grade. Assume the soil weighs 15.78 KN/m3 and the allowable soil pressure is 190 Kpa. Use 75 mm as concrete cover, fc’ is 28 Mpa, fy is 415 Mpa, and concrete weights 23.5 KN/m3. Compute the: Width and depth of footing Spacing...

A 2.8 m wide reinforced concrete strip footing is situated at 2.5 m below ground level in a thick deposit of a saturated clay. The footing is loaded centrally, and the total vertical line load including the weight of the concrete and backfill is 308 kN/m. The clay has a bulk density (ρ) of 2250 kg/m3 and an undrained shear strength (cu) of 42 kPa. a) Calculate the factor of safety against bearing capacity failure considering the short term response...

A reinforced concrete bearing wall supports 12” wide beams bearing on the full width of the wall spaced 10’ o.c. The bottom of the wall is a fixed connection. The top of the wall is a pinned connection. The wall is 20’ tall. The load from each beam, Pu, is 30 kips. Determine whether a 10” wide wall will work for this condition. Select vertical and horizontal reinforcing steel.
