The bearing capacity of strip footings on unsaturated soils is studied using slip line theory. The suction profiles considered are non-uniform with depth and correspond to vertical flow of water by infiltration or evaporation. The slip line theory assumes a plastic equilibrium state of a Mohr-Coulomb soil in which suction influences are included using the effective stress concept. This paper sh...

The common modeling assumptions in analyses of structural response considering the effects of soil-structure interaction are discussed, as well as their consequences. Issues such as spatial variability of strong ground motion and flexibility of building foundations are specifically addressed. Results are shown for the case when spatial variability is considered, but inertia interaction and kine...

Rocking isolation of structures is evolving as an alternative design concept in earthquake engineering. The present paper investigates the seismic performance of an actual overpass bridge of the Attiki Odos motorway (Athens, Greece), employing two different concepts of rocking isolation: (a) rocking of the piers on the foundation (rocking piers); and (b) rocking of the pier and foundation assem...

following the recent work of the authors in development and numerical verification of a new kinematic approach of the limit analysis for surface footings on non-associative materials, a practical procedure is proposed to utilize the theory. it is known that both the peak friction angle and dilation angle depend on the sand density as well as the stress level, which was not the concern of the fo...

Power transmission lines routes mapping is an important technique for locating power transmission line routes andtowers on mountain/hilltops to assist viewing of their impacts on the environment, operations and allocation of publicutilities. A study was therefore conducted to map the power transmission lines within Bukit Lanjan PLUS highway. Themain objective of this study is to ass...

This paper describes an innovative design of a newly developed large test setup for testing the performance of footings supported on soft clay reinforced with granular columns. This advanced testing method is used to examine the settlement of footings supported on granular columns. Two important features of the equipment are a the axial loading system which allows samples to be consolidated und...

This paper shows a general model of rectangular footings to obtain the soil minimum contact area (optimal surface) that support from 1 n columns aligned on longitudinal axis. The proposed considers pressure varies linearly. recently published models have been presented individually for isolated footings, combined two columns, these present equations, but it is not guaranteed be area. research c...

although bearing capacity of footings on top of slopes under monotonic loadings have been investigated widely so far, safety and bearing capacity of these structures against repeated dynamic loads have not been considered well enough. in this paper, lower bound dynamic shakedown theorem in its numerical form has been employed to firstly obtain bearing capacity of strip footings on top of slopes...

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...
