... was not carried out, the depth of bed rock was assumed at that depth where the calculated shear wave velocity was about 600 m/s, (Ohta and Goto, 1978). The main geotechnical parameters required for the analysis of seismic site response were unit weight, small-strain shear modulus and damping, and the variations...

... Island where field studies of in situ wave velocity were under taken and laboratory tests performed on high quality samples. Results from the field tests are presented as profiles of shear wave velocity at low strain, while the laboratory results present wave velocity measurements and shear modulus...

... needed for the earthquake analyses were the velocity of the shear wave, the dynamic shear modulus and the damping ratio. Because direct measurements on the site were not possible, seismic soil parameters for earthquake analyses were determined as based on laboratory tests on samples from the bridge site...

..., the shear modulus, which is one of the key parameters required in conducting earthquake response analyses, could not be directly evaluated in these studies. In the present study, therefore, a torsional shear testing apparatus was newly introduced (refer to Koseki, et al., 2000 for details of the apparatus...

... ABSTRACT: This paper presents study of the effects of initial fabric on the cyclic deformation characteristics such as shear modulus and damping ratio from drained static cyclic tests on Toyoura sand using hollow cylinder apparatus. The apparatus allows independent control of stress components...

... ABSTRACT: A simple method to estimate liquefaction- induced deformation was developed to estimate the settlement of river levees. In the analyses the author assumed that the residual deformation would occur in liquefied ground due to the reduction of shear modulus. Selected levees were damaged...

... measurement. The shear modulus of densified sandfill can also be evaluated by the cone resistance; however, the shear modulus of freshly deposited sandfill cannot be correlated with the cone resistance.

... required; these were the shear modulus, G, of the marl within the joints of the upper rock layer which was estimated to be 8000 kPa, and the coefficient of volume compressibility, mv' of the marl layer which was esti- mated to be 6x10-5 m2/kN. 3 THEORETICAL CONSIDERATIONS 3.1 Background Layered elastic...
