Abstract

The foundation is the foundation or the lowest structure that transmits the load of the building to the soil layer below it. If the foundation receives the load not concentrated (eccentric), it will be very dangerous for the building. This will result in construction failure due to foundation design errors. There are several problems discussed in this study, namely how to overcome eccentricity, and how to increase the bearing capacity of the footing if there is an eccentricity that works. This study was made with several variations, including: increasing eccentricity variations, variations in soil groups, namely bad soil, medium soil, and good soil (AS 4678, 2002), variations in soil depth (Df), and also variations in the addition of foundation length (L). ). The data used in this study is from the help of secondary data. The modeling form is the footing foundation with a cantilever structure load on it. The size of the cantilever is obtained from its own assumptions, which are 2 x 1.5 m, 2 x 2 m, 2 x 2.5 m, and 2 x 3 m. Calculation of the bearing capacity of the footing using the Meyerhof vertical load method and analyzed using the Microsoft Excel application. The soil parameters used, among others, on poor soil: effective soil volume weight (γ') 7.19 kN/m3, cohesion (c) 2.5 kN/m2, friction angle (φ) 21˚. Medium soil: effective soil volume weight (γ') 9.19 kN/m3, cohesion (c) 1.3 kN/m2, friction angle (φ) 29˚. Good soil: effective soil volume weight (γ') 13.19 kN/m3, cohesion (c) 0 kN/m2, friction angle (φ) 35˚. The result of the research is that the eccentricity and the bearing capacity of the foundation (qult) can be overcome by increasing the length of the foundation (L) towards the x-axis, the better the soil type, the higher the foundation bearing capacity (qult) and the smaller the foundation length (L). , the deeper the foundation is placed into the soil, the value of the soil bearing capacity (qult) will increase.
