mySpec calculates the response of a SDoF or 2DoF system subjected to seismic or user defined excitation.
The analysis may be linear elastic or non-linear. The response is calculated for several models, including linear elastic, bilinear inelastic, and Bouc-Wen. The typical excitation corresponds to a ground motion specified by an earthquake. However, an arbitrary excitation force can be used as well, either alone or combined with an earthquake. The free vibration after the excitation can be evaluated as well. All diagrams of interest can be plotted on the screen or sent to the printer. Also, the results can be exported in the form of ASCII text files. The program is capable of producing a simulation of the behaviour of the system in animated form, idealised as a lumped mass on the top of a massless column.
