Skirted foundations are an appropriate alternative to deep foundations in onshore and offshore structures, which have the ability to withstand uplift loads, are also easy to be installed. The tensile performance of skirted foundations on sand was studied by physical and numerical modeling. Laboratory tests were carried out on small-scale foundation models with peripheral skirts. Numerical model...
in this study, a researching program is conducted by cyclic triaxial test to determine the post-cyclic behavior of bushehr carbonate sand retrieved from the north of the persian gulf, under anisotropic consolidation at 200 kpa confining pressure. the article compares the post-cyclic monotonic strength and excess pore water pressures generated after the test with the pre-cyclic monotonic results...
Despite some studies on bearing capacity have been studied, the detail responses of the suction bucket foundations under dynamic loads have remained unknown [3]. The dynamic load condition is significant when suction buckets are used as the foundation of an offshore structure. Wave load, ice-induced or wind-induced load cause the foundation to be subjected to cyclic loads [4]. The dynamic load ...
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 ...
numerical assessment of influence of confining stress on kaiser effect using distinct element method
nowadays acoustic emission (ae) testing based on the kaiser effect (ke) is increasingly used to estimate the in-situ stress in laboratories. in this work, this effect is assessed on cylindrical specimens in numerical simulations of the cyclic loadings including loading, unloading, and re-loading cycles using a 3d code called the particle flow code (pfc) based upon the distinct element method. t...
Formation elastic properties near a borehole may be altered from their original state due to the stress concentration around the borehole. This could lead to a biased estimation of formation elastic properties measured from sonic logging data. To study the effect of stress concentration around a borehole on sonic logging, we first use an iterative approach, which combines a rock physics model a...
This paper presents a low cycle fatigue life curve by simulating a crack in a cover plate welded moment connection. Initiation of ductile fracture in steel is controlled by growth and coalescence of micro-voids. This research used a numerical method using finite element modeling and simulation of ductile crack initiation by a micromechanical model. Therefore, a finite element model of a cover p...
carbonate materials are mostly found in tropical areas, where exploiting gas and oil resources are of high concern. their unique behavior under shear loading first was recognised during oil resources investigations in the persian gulf. off-shore structures have been placed on carbonate soils which are highly crushable.during storms cyclic loading imposes on the bases of structures lied down on ...
