The aim of this paper is to study the effects of Soil-Structure Interaction (SSI) on the seismic response of coupled wall-frame structures on pile foundations considering the non-linear behaviour of the superstructure. According to the substructure method, the kinematic interaction analysis is performed by means of a numerical procedure obtaining the dynamic impedance functions and the foundati...

Previous case histories have shown that soil liquefaction severely damaged many structures supported on pile foundations during earthquakes. As a result, evaluating the potential for instability is an important consideration for the safe and resistant design of deep foundation against earthquakes. In this study, the liquefaction susceptibility of saturated sand interacting by single concrete pi...

The U.S. Air Force used the chlorinated pesticide, chlordane, to control termites around base housing until it was banned in 1988. As bases are closed, contracted, or realigned, soil issues associated with this pesticide must be addressed. One issue that is not well understood is chlordane volatility. There are documented cases where chlordane applied to soil resulted in vapor intrusion into bu...

Suction caissons have recently been considered as a cost effective alternative to conventional foundations for offshore met-masts and wind turbines. Such foundation arrangements are suitable for applications within water depths of 20-30m. Most offshore structures have stringent serviceability limit states imposed on their design dictating the allowable structural deflections and accumulated rot...

Windmill, machine that converts wind into useful energy. This energy is derived from the force of wind acting on oblique blades or sails that radiate from a shaft. The turning shaft may be connected to machinery used to generate electricity. The present paper makes an attempt to show the effect of wind and earthquake load on tubular type windmill and its foundation considering hard, medium and ...

the interactive effects of adjacent buildings on their seismic performance are not frequently considered in seismic design. the adjacent buildings, however, are interrelated through the soil during seismic ground motions. the seismic energy is redistributed in the neighboring buildings through multiple structure-soil-structure interactions (sssi). for example, in an area congested with many nea...

this paper deals with three-dimensional evaluation of the slopes on the basis of limit analysis. an upper-bound technique of limit analysis is used in this paper to determine either the bearing capacity of a shallow foundation near a slope or the safety factor of the slope. the theorems of limit analysis (upper and lower bound) provide a powerful tool for solving problems in which limit loads n...
