The finite strip method is used to study the dynamic response of surface strip foundations. This method is simple to use and versatile. The two‐dimensional problem is effectively reduced to an equivalent one‐dimensional problem. The choice of trigonometric series for the displacement functions results in the uncoupling of the terms of the series and a significant reduction in the semi‐bandwidth of the complex set of equations, making the method well suited to small computers. Non‐homogeneous soil profiles are treated as a matter of course. The finite strip solutions are shown to be in general agreement with other theoretical methods of analysis.
