In this paper, the influence of soil-structure interaction (SSI) on a torsionally coupled turbo-generator (TG) machine foundation is studied under earthquake ground motions. The beneficial effects base isolators in TG motions are also duly, considering SSI. A typical analyzed using three-dimensional finite element (FE) model. Two superstructure eccentricity ratios considered to represent torsio...

Observations of the beam-beam interaction at SPEAR, CESR, PETRA and PEP are discussed. They are sufficiently similar that a simple prescription can be formulated to describe the behavior of the luminosity as a function of current including the peak values. With this prescription the interpretation of various methods of increasing the luminosity, such as the reduction of the vertical betatron fu...

background: gold nanoparticles are emerging as promising agents for cancer therapy and are being investigated as drug carriers, photothermal agents, contrast agents and radiosensitisers. objective: the aim of this study is to understand characteristics of secondary electrons generated from interaction of gold nanoparticles gnps with x-rays as a function of nanoparticle size and beam energy and ...

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...

There are varieties of techniques for calculating natural frequency of the structures. Nevertheless, these equations are less developed in the geotechnical structures such as slopes, buttress group, dams, and retaining walls. In earth dams, with respecting to the dimensions and weight of dam, soil-structure interaction is of prime importance for finding seismic parameters including natural freq...

This paper describes an analytical approach to conduct analysis of beam-column elements with generalized end-boundary conditions on a homogeneous or non-homogeneous Pasternak elastic foundation. The mathematical formulation utilized herein is that presented by the senior author in recent work. differential equation (DE) governing behavior element solved using transformation method (DTM). DTM of...

A p-y curve method of pile near cohesionless soil slope under reversed lateral load is proposed. This takes into account the failure mode around and interaction between soil, derives ultimate resistance pile. Considering change original stress state due to deflection foundation, influence relative density, initial mean effective foundation on internal friction angle sand evaluated further accur...
