In the first time utilizing of pile in construction, designers had used assumption that piles can carry axial force only, so to resist lateral force is used batter piles. But recently vertical pile should be designed can carry lateral forces too. Pile analysis loaded lateral force can be determined from the following two criterias: 1. Be based on load and deflection relationship, and 2. Be based on ultimate load that pile/foundation can carrying on There are two theoretically approaches that used to determine lateral deflection, they are: 1. Sub grade reaction approach, and 2. Elastic approach In this article, the employed analysis is observed be based on load and deflection relationship with sub grade reaction approach. With this approach is executed parameters influence analysis to piles behavior. The results show that: lateral deflection occurred on a pile will decrease if a pile more rigid. But on the other way bending moment and shear force will increase. Added length of a pile real influential for added lateral deflection of pile head and maximum bending moment before exceed effective’s length. After exceed effective’s length, added length of a pile no again real influential for added lateral deflection of pile head and maximum bending moment. Lateral deflection and moment taken place on a pile will decrease if value of sub grade reaction modulus increase. |
