TL;DR: In this article, the effect of frequency of cyclic loading on liquefaction and post-liquefaction resistance of original Ahmedabad sand has been presented in a technical paper.

TL;DR: In this article, the authors carried out the seismic microzonation of a nuclear power plant site situated in the east coast of South India, based on the spatial distribution of the hazard index value.

TL;DR: In this paper, a detailed study on the postliquefaction undrained shear behavior of sand-silt mixtures at constant void ratios is presented, in which the influence of different parameters such as density, amplitude of cyclic shear stress, and drainage conditions on the response of sand silt mixture has been investigated, in addition to the effect of fines content.

TL;DR: In this paper, the authors presented a case study on the vibration isolation scheme adopted for an important building of space research agency, where the vibration levels in the building had to follow the vibration criterion which is in the form of a set of one-third octave band velocity spectra, expressed as vibration criterion curves.

TL;DR: From the results, the shear modulus and damping ratio have been estimated for a range of shear strain and confining pressure and the DEM simulations have modeled the liquefaction behaviour under undrained conditions very close to the real experimental behaviour.
