Abstract |
This paper presents a method to increase the strength of reinforced concrete foundations. In the proposed method, a steel plate was placed in the foundation to increase the strength of concrete strut. Eight foundations were tested in order to verify the proposed method. Three main parameters were considered in the experimental investigation: the strengthening of steel plate (without or with plate), depth of foundation (430 mm, 500 mm, and 700 mm), and loading ways(one- or two-way loading). The test results indicated that the steel plate in the diagonal concrete strut increased the strength of foundations. In addition, the strength of foundation calculated by a strut-and-tie model predicted more accuracy with the test results than that calculated by KCI-07 design code. |
