Tripartite Graph for Response Spectra

Tripartite Graph for Response Spectra

Tripartite Graph for Response Spectra

I'm trying to find a software that I can use to plot four-way logarithmic graphs (response spectrum). Right now I'm doing this by hand. In addition I'm trying to find a software to construct smoothed response spectra out of attenuation relationships

This will be used to construct plots for various site-to-source distances values an so on. If someone can provide me any assistance on this matter I will be very gratefull



RE: Tripartite Graph for Response Spectra

Check out Geotechnical Earthquake Engineering by Steven L. Kramer and I believe that Mario Paz had the procedure in his text, Structural Dynamics.

RE: Tripartite Graph for Response Spectra

We at GEO-SLOPE will be launching a new version of our QUAKE/W product in October which will include support for spectral analysis of ground motion frequency characteristics.

Please visit our web site at http://www.geo-slope.com/version5/ for more information.

Warm regards,

RE: Tripartite Graph for Response Spectra

Try DaDisp.  This is a useful package that does analysis and plotting of essentially any type of formatted data, including various transforms, spectra analysis, and I think later versions support "waterfall" plots as you are requesting.

White Paper - The Criticality of the E/E Architecture
Modern vehicles are highly sophisticated systems incorporating electrical, electronic, software and mechanical components. Mechanical systems are giving way to advanced software and electronic devices, driving automakers to innovate and differentiate their vehicles via the electric and electronic (E/E) architecture. As the pace of change accelerates, automotive companies need to evolve their development processes to deliver and maximize the value of these architectures. Download Now
White Paper - Model Based Engineering for Wire Harness Manufacturing
Modern cars, trucks, and other vehicles feature an ever-increasing number of sophisticated electrical and electronic features, placing a larger burden on the wiring harness that enables these new features. As complexity rises, current harness manufacturing methods are struggling to keep pace due to manual data exchanges and the inability to capture tribal knowledge. A model-based wire harness manufacturing engineering flow automates data exchange and captures tribal knowledge through design rules to help harness manufacturers improve harness quality and boost efficiency.

White Paper - Modeling and Optimizing Wire Harness Costs for Variation Complexity
This paper will focus on the quantification of the complexity related costs in harness variations in order to model them, allowing automated algorithms to optimize for these costs. A number of real world examples will be provided as well. Since no two businesses are alike, it is the aim of this paper to provide the foundational knowledge and methodology so the reader can assess their own business to model how variation complexity costs affect their business.
