Summary on Grant Application Form |
|
An experimental testing programme on Hostun sand is proposed using a Hollow Cylinder Torsional Apparatus. The behaviour characteristics in the small strain and medium strain domains (up to some 10a m/m) under the complex stress states, which are accessible with this apparatus, will particularly be explored. An accurate evaluation of soil stiffness for this strain domain is essential when prediction of instantaneous deformation of ground and displacement of structures under seismic loading are considered. The terms of the incremental compliance matrix relating stress increments and strain increments will be evaluated and the evaluation of these terms with the strain and stress states and with cyclic strain amplitude will be analysed.For these purposes, the Hollow Cylinder Torsional Apparatus will be upgraded. Fully independent measurements of stress and local systems of measurement of strains will be developed in order to allow sensitive and accurate stns and strain measurements in the small strain domain. The apparatus will also be adapted to follow the loading up to large strains. A new computerised control system will be achieved. In order to validate the apparatus and to explore its full limits, an extended testing programme on Hostun sand up to failure will be performed.
