چکیده
This paper provides insight into the behavior of a stiffened caisson anchor under inclined cyclic loading in calcareous silt. A series tests was conducted beam centrifuge. monotonic test first performed, quantifying pure capacity, and then four varying mean load, amplitude, number cycles. Cyclic soil characterization T-bar were linked. Undrained led to generate excess pore pressure, resulting degradation strength stiffness. For partially drained tests, pressure generated during initial undrained experienced partial dissipation. Healing due consolidation outweighed damage generation. Postcyclic capacity found be up 35% higher compared with unless failed loading. Measured rotation indicated evolution failure mechanism. Caisson presented as envelope, effect accentuated. The contribution soil–chain interaction on minimal. No trenching apparent surface, no gap formed around considered centrifuge testing conditions.

The Behavior of Suction Bucket under Cyclic Loading in Saturated Lands
Numerical modeling was carried out to investigate the responses of suction bucket foundations under vertical cyclic loading. Numerical results were compared with centrifuge experiment results. Before the capacity of the model suction bucket to resist cyclic loading could be investigated, the static pullout capacities had to be determined. The buckets with different aspect ratio are investigated...
متن کاملSubstructure Model for Concrete Behavior Simulation under Cyclic Multiaxial Loading
This paper proposes a framework for the constitutive model based on the semi-micromechanical aspects of plasticity, including damage progress for simulating behavior of concrete under multiaxial loading. This model is aimed to be used in plastic and fracture analysis of both regular and reinforced concrete structures, for the framework of sample plane crack approach. This model uses multilamina...
متن کاملOn the effect of grain size on rock behavior under cyclic loading by distinct element method
It is well-known that the mechanical behavior of rocks under cyclic loading is much different from static loading conditions. In most constructions, the load applied to structures is within dynamic ranges. That’s why a great deal of attention has been paid towards this field in order to identify the dynamic behavior of rocks in more details. Nevertheless, the nature of dynamic failure in rocks ...
متن کاملComparison of Radial Consolidation Behavior of Clay under Three Types of Cyclic Loading
Vertical drains and stone columns which have been used in infrastructure construction for highways, ports, coastal regions, etc., provide significant benefits for improving soil characteristics such as reducing the drainage length and accelerating the consolidation process. So the investigation of the radial consolidation is inevitable. Soils may be subjected to cyclic loading such as silos, ta...
