Ground response analysis Name: Institution: Date: Ground response analysis Analysis of local site response is a fundamental aspect of geotechnical earthquake engineering. This is due to its ability to facilitate incorporation of properties linked to sub-surface materials alongside topographical aspects in prediction of the amplitude, content of frequency, as well as ground motion surface duration as a result of specific ‘bedrock excitation’ input…
In this report, two parts are considered. In the first part, a ground response analysis for two sites is run while the second part proposes possible design accelerations on basis of the analysis in designing of an embankment structure that will support the proposed roadway. Both of the proposed sites are located in Jamaica. With regard to ground response analysis, edushake analysis program is made use and the results obtained are as displayed in the various tables displayed throughout this report. The input data used are as provided in the coursework materials while the thickness is obtained through calculation of the difference between the depths. A table from the web forms the basis of assumptions made with regard to respective soil’s unit weight. Each soil type has its respective stress (??), pore pressure (u) as well as effective stress (??’) associated with it (Bhandari and Sharma, 2001). Two equations, one for sand and the second one for clay are used in in calculation of maximum shear stress based on the literature from the book of Steven Kramer’s. ...
