The data represent experimental results from direct shear tests and dynamic shaking table tests performed at University of Bristol on the feasibility of using a sand-rubber deformable granular layer as a low-cost seismic isolation strategy for developing countries.
Each of the files Fig._(Figure number).csv contains the data for the reproduction of the figures 4, 5, 6, 7, 8, 9, 10, 11, 12, 15, 16, 17, 18, 19, 20, 21, 22 and 23 that are included in the paper.
Each column in any of these files represents a variable presented in the figure and the corresponding units are given in a bracket next to the title of the variable.
The data are given in three decimal places except for the acceleration data, which are given in five decimal places.
