Seismic Protective Systems

How do you effectively understand seismic risk and implement seismic protection?

Achieving seismic performance requires the control of both deformations and accelerations within a structure; however, very few conventional structural systems allow the engineer to reduce both simultaneously. Advanced seismic protective systems such as base isolation, passive and semi-active damping devices, and re-centering walls and frames improve pre-event damage-resistance and post-earthquake functionality.

How we work

Ģ��tv's seismic protection consulting starts with a feasibility study, followed by detailed structural analysis, device testing, and peer review to help ensure clients reach their specific seismic protective and performance goals. Our design approach requires a deep understanding of seismic protective systems mechanics and the practical experience to implement them in an appropriate, cost-effective way. With experience in nuclear plants, healthcare facilities, and other commercial and industrial structures, we work seamlessly through regulatory compliance processes and peer reviews specific to a variety of domains.

How we quantitatively assess seismic risk and offer solutions

Once a client decides to implement seismic protective systems for a project, we begin extensive analysis, including detailed nonlinear dynamic finite element analysis. Ģ��tv's seismic engineering team has expertise selecting and scaling ground motion records, developing nonlinear finite element models that feature advanced seismic protective devices, and efficiently post-processing results in design and detailing use. Additionally, we can assist with probabilistic risk assessments of structures equipped with these devices to better assess their benefits relative to conventional designs.
