One of the most common marine structures is anchored concrete quaywall. Obviously, anchoring the wall will reduce the penetration depth, maximum bending moment and lateral displacement of wall in both static and dynamic conditions. In this research, first, effect of tierod position in anchored concrete quaywalls in primary static condition is considered and compared with two methods: “Free Earth Method” and “Finite Difference Method”. Also, practical curves of "maximum moment" and "tierod axial force" are given versus r (ratio of tierod depth to wall length) in static condition. Then, dynamic response of different cases (various tierod depths) is illustrated and
compared. Practical history curves of “maximum positive and negative moment”, ”tierod axial force” and “lateral displacements” are provided via “Finite Difference Method”. Analyzing these charts, influence of tierod position on anchored quay walls in seismic condition is investigated about seismic behavior and rehabilitation of the structure. Suitable tierod position results in better serviceability and lower maximum moment in concrete quay wall profile and therefore economical one.<\div>
