The inelastic response of a two-storey framed structure has been studied under
the Traft Earthquake of July 21, 1952, N 69 W component. Idealized bilinear
resistance-deformation relationship has been assumed for each storey. The nondimensionalized
equations of motion have been numerically integrated by the
Newmark-b-procedure to obtain the response. The main system parameters
varied are the frequency ratio and the yield ratio. A minimum value for the
maximum response of the lower storey has been obtained in this range of values.
The response history and the dynamic force-deformation curve has been
presented for this optimum set of system parameters. The dissertation has been
concluded with a few suggestions for further work.
