The beam will be reused and will be required to carry an elevator car with an induced Vu = 500kN. Determine the required additional concrete that shall be placed below the beam so that the existing spacing of the stirrups can be enough to resist the loads. Hint: (This is a trial-and-error problem. Try to solve by adding only 100mm and check if Vc and Vs are satisfied as per procedures in the lesson. If not, add additional 100mm until a final section is obtained)

Give full explanation Awall form 14 ft high is filled with 160 lb per cu ft concrete at a tem perature of 70°F. The concrete is Type I without a retarder. Concrete will be placed with normal internal vibration to a depth of less than 4 ft. The rate of placement is 5 ft per hr. From Table 1, the value of Cw is 1.1 and from Table 2 the value of Cc is 1.0. The rate of placement is less than 7 ft per hr and the place ment height does not exceed 14 ft so calculate the lateral pressure by using appropriate formula.
