Ever wondered what it is that keeps a building standing during an earthquake? Good question! To make sure a building can weather an earthquake, engineers employ seismic analysis. Seismic engineering involves a deep understanding of the soil under a building, its composition, and how it behaves under stress. 😬 👷♂️ Enter Chris Mathews, P.E., our Geotechnical Engineer/Project Manager and seismic expert. Through sophisticated methods and consideration of soil conditions, seismic site class, and various testing techniques, Chris and his team ensure that each building is not a basic structure but a resilient building ready to face the forces of nature head-on. The science of seismic engineering keeps our world standing strong! Want to know more about seismic analysis? 🌍🚨 Read our blog post: https://lnkd.in/g7-hRkc8 #EngineersOfLinkedIn #Innovation

The first draft of the hotly anticipated technical specification 1170.5 Structural design actions - Part 5: Earthquake actions - New Zealand is ready for public comment. TS 1170.5 aims to provide a means for engineers to voluntarily test, and put into practice, new technical specifications within the context of the updated National Seismic Hazard Model (NSHM) released in October 2022. The NSHM, calculates the likelihood and strength of earthquake shaking that may occur in different parts of Aotearoa New Zealand over specified time periods. It is used to improve our resilience and manage risks to safety, security and the economy from seismic events.

An important new piece of the engineering toolkit when considering seismic design. Let's ensure we get appropriate input to help manage the future of our building stocks here in Aotearoa.

Announcing the publication of our latest collaboration titled 'Seismic Performance Assessment of Corroded Water Distribution Systems Considering Firefighting' (Authors: Weinan Li, Ram Krishna Mazumder, Emilio Bastidas-Arteaga, Yue Li) in the Journal of Water Resources Planning and Management, ASCE Publishing. In this study, we crafted a model designed to assess the resilience of water distribution systems after an earthquake, incorporating considerations for post-earthquake firefighting and the corrosion-induced deterioration of pipeline systems. #ASCE, #waterdistribution, UESI - Utility Engineering and Surveying Institute, #SeismicResilience, #firefighting

In this paper, a new potential earthquake-induced landslide risk model is proposed for mountain railway alignment optimization, integrating probabilistic seismic hazard analysis, critical acceleration computation, and landslide displacement estimation. https://lnkd.in/gncqQ6Gh

Reflecting on Japan's recent earthquakes, valuable lessons have emerged from this catastrophic event. While Japan adheres to robust earthquake design standards, there's a clear need for enhanced infrastructure resilience to effectively face severe seismic events. I've delved into this by authoring a paper on the seismic behaviors of long-span bridges supported on deep foundations in both liquefiable and non-liquefiable soil conditions. My exploration revealed that piles stand out as the most fragile component in both non-liquefiable and liquefiable conditions. Additionally, the reinforced concrete pier displayed a significant drift response in non-liquefiable soil, rendering it more susceptible to seismic hazards compared to liquefiable soil. These findings underscore the imperative for further research and industrial practical measures to fortify infrastructure resilience, ensuring safer communities in the face of seismic challenges.
