Six buildings were overturned in the town of Onagawa during the 2011 Great East Japan tsunami. This study investigates the possible failure mechanisms of building overturning during tsunami flow. The tsunami inundation depth and flow velocity at each overturned building were recalculated by using a tsunami numerical simulation and verified using a recorded video. The overturning moment is a res...

This technical note presents the results of a field investigation into pile aging in soft clay which was conducted over a period of ten years. Static load tests were conducted after the excess pore pressure generated by the installation of 6 m long driven concrete piles were fully equalised. These tests allowed the time-capacity aging profile to be established. A normalised capacity-time trend ...

The reliability index is an important reliability parameter that is necessary for the development of reliability-based geotechnical design. Both the factor of safety (FS) and the reliability index (β) represent safety margin of structures against either failure or limit state. In this study, the reliability index is analyzed and evaluated in reference to the factor of safety currently adopted i...

Bearing capacity of single piles are occasionally predicted using the renowned theoretical methods (α and β methods). These based on laboratory tests, which can be time-consuming, but also applicable in foundation engineering practice for unsaturated soils. Full-scale pile load tests were carried out bored equipped with Expander Body Systems Federal District Brazil, known its unsaturated, colla...

in this study, a bearing capacity device is designed and fabricated to determine the load-settlement behavior of three circular footing models resting above the ground water table. capillary rise in the studied well graded sand is measured and the level of the water table is controlled at the desired heights during each bearing capacity test. moreover, shear strength parameters and soil water r...

The application of pretensioned spun high-strength concrete (PHC) piles in high-intensity seismic areas has been limited by insufficient horizontal load resistance and poor deformation capacity. A new type pile with high-elongation steel strands instead bars developed. This paper presents a flexural performance evaluation the centrifugal (hereafter referred to as PSC pile). An experimental stud...

The pile’s ultimate capacity or failure load must be computed by some criteria using load-settlement curve data gathered during the pile test. Many scholars have proposed several approaches for evaluating in past. This study compared different to predict piles with two lengths-to-diameter ratios embedded gypseous soil gypsum content of 60% under soaked and unsoaked conditions. Two types were us...

The purpose of this work was to determine the increase limit load when resting foundation slab on ground at a different pitch piles and their length. main task is calculate combined pile-slab foundation. hypothesis that in work, bearing capacity entire structure increases. This calculated using Plaxis 3D design software complex. In article, we have determined value by which ultimate increases r...

This paper presents the horizontal bearing characteristics of piles in coral sand and silica from comparative experimental studies. Six model with different diameters were tested. The capacity, deformation characteristic, bending moment, p–y curve, change soil pressure, as well particle breakage behaviour investigated. results show that, foundation, capacities increments pressures are obviously...

In this paper, the analysis of a numerical study for consolidation short bored pile subjected to axial loads is presented. An short-bored performed using finite element software Abaqus CAE with base procured experimental data in sand media and comparative on Ansys FEA. Three models combination footing system were developed by application incremental load which displacement upon each was analyze...
