Abstract:

Pile-wharfs are berthing structures built parallel to the shoreline and ensure berthing of vessels from one side, pile-wharfs are berthing structures built perpendicular to the shoreline and ensure berthing of vessels at two or more sides. Main structural system of a wharf structures are piles built in a batter-vertical direction with platforms.In both type of shore structures, significant rate of damage occurs due to soil-pile interaction together with horizontal loads. Irreparable deformations may occur with the pillars. In the numerical model which will be established to determine the distribution of damages that may occur and damage rates and to simulate the structural behavior, soil-pile interaction in pile sections which are exposed to significant plastic deformation shall be represented with nonlinear springs.Vessel impulse at harbors and coastal structures, wave loads, clamping loads and seismic activities are examples to horizontal loads which shall be taken into consideration in the design and evaluation problem for wharf structures. Design criteria of such type of structures are recommended to be established according to the maximum deformation capacities instead of load bearing capacities of the piles in the recent years. Since mainly seismic activities and base parameters will trigger the deformation in piles, horizontal load bearing capacities shall be calculated to include the above mentioned effects.Turkish Code for shore structures (TCSS, 2008) requires representation of this effect with non-linear springs in the numerical model for consideration of soil-structure interaction in design and evaluation of pile wharf structures. In this case, non-linear interaction between structure and soil will be taken into consideration.This study aims to present the non-linear static analysis (push-over analysis) of vertical and batter pile wharfs according to the conditions of TCSS, 2008. Besides, horizontal load bearing capacities for different soil conditions and maximum displacements were analyzed for batter/vertical pile wharf structures separately. In this context, in vertical pile wharfs built on stiff soil, even if high values of lateral displacement at all monitored points have been obtained, less plastic hinge rotations at pile cross sections reached their capacities. However, in batter pile wharfs, even if the structure leads to level of lateral displacements, plastic hinge rotations at pile cross sections reached their capacities and mechanism occurred earlier than expected.
