Displacement-based design is gaining popularity among NZ structural engineers and is often used as an alternative to the traditional Force-based design. This paper delves deeply into some of the key differences between these methods. We are very keen to collaborate with other engineers regarding their findings and opinions about displacement-based design.

We’d like to hear your thoughts about this paper. Email the author at:

Comparison between NZS 1170.5 Seismic Design Spectra and Hysteresis-Damped Spectra​

Caudillo, our teammate here in StruktEQ, has recently published a paper regarding displacement-based design on the Bulletin of the New Zealand Society for Earthquake Engineering, Volume 50, No. 1, March 2017. The paper is titled “Comparison between NZS 1170.5 Seismic Design Spectra and Hysteresis-Damped Spectra” and a copy can be downloaded here:
