General Description
BISPEC is a user-friendly program that computes Linear and Nonlinearspectra of earthquake records. Bispec can also be used to analyze a single SDOF system under any ground acceleration record, and plot the displacement or force response over time. You can even watch an animation of the shaking in real time!
Since real earthquakes are not Unidirectional, each earthquake in Bispec can have either one or two components, which makes it easy to generate spectra for two directions (Bidirectional), as well as spectra for the 2D resultant of the two directions (Planar Spectra).
The program offers great flexibility for changing the dynamic properties of the SDOF system, such as Mass, Stiffness, Period and Damping.
In addition to elastic response, the nonlinear response of the structure can be specified by here, and please come back again. If you are not Thai,and want to post or ask for someone to help, please go to "International Board"
