Because offshore wind turbines are high-rise structures, they transfer large horizontal loads and moments to their foundations. One of the keys to designing a foundation is determining the sensitivities and laws affecting its load-bearing capacity. In this study, this procedure was carried out for a new high-rise cap pile group foundation adapted to the loading characteristics of offshore wind ...

The influence of combined loading on the response monopiles used to support offshore wind turbines (OWTs) is investigated in this paper. In current practice, resistance vertical and lateral considered separately. As OWT size has increased, slenderness ratio (pile length, L, normalised by diameter, D) decreased foundations are tending towards intermediate footings with geometries between those p...

Unbound aggregates are the most common type of materials used for construction of the base layer of flexible pavements in Iran and worldwide. Due to the lack of binder, the performance of the compacted unbound aggregates is highly dependent on the properties of the gravel (particles remaining on sieve 4.75mm, sand (particles passing sieve 4.75mm and remaining on sieve 0....

In the design of reinforced concrete rectangular footings subject to axial load and flexure in two directions, there are different pressures in the four corners, these are exercised by soil. In this paper, a mathematical model is developed to take into account the real pressure of soil acting on the contact surface of the footings, these pressures are presented in terms of the mechanical elemen...

For a reinforced concrete beam subjected to fatigue loads, the structural stiffness and bearing capacity will gradually undergo irreversible degeneration, leading to damage. Moreover, there is an inherent relationship between the stiffness and bearing capacity degradation and fatigue damage. In this study, a series of fatigue tests are performed to examine the degradation law of the stiffness a...
