Look out for our paper today titled "Seismic Fragility of Helical Pile Supported Bridge in Cohesive Soil". This study delves into the seismic fragility of a three-span highway bridge supported by helical pile foundations in cohesive soil. Through nonlinear time history analyses and Incremental Dynamic Analysis, fragility curves are derived for each damage limit state. The study identifies piers in the superstructure and helical piles as the most vulnerable components during seismic events.

Development of seismic retrofit technique of RC Frame using fully fastened haunch elements: Static to dynamic testing! In this paper an innovative method for seismic retrofitting of poorly detailed reinforced concrete beam-column joints and structures using haunch type elements connected with post-installed anchors is discussed. During an earthquake, the global behaviour of the structure significantly depends on behaviour of the beam-column connections, but no special emphasis was given to that till the eighty’s.

We are pleased to share a video simulation comparing fixed and isolated structures following the previous post. See how seismic isolators reduce base shear force by 62%, enhancing safety and reducing construction and repair costs. Watch now to understand the crucial impact of Lead Rubber Bearings (LRB) on structural performance during earthquakes. 📉🏗️ My Partner : Oussama Himmich

On this day in 1959, the Structural Engineers Association of California (SEAOC) Seismology Committee published the first edition of the Blue Book. This document was the first to outline the relationship between earthquake demands, building period, and the ductility of various lateral force-resisting systems. Such relationships became the standard for designing lateral force-resisting systems. In fact, other code provisions such as the Uniform Building Code have incorporated it into their lateral force requirements. Subsequent editions of the Blue Book continue to serve as a basis for seismic design today. Read more about the Blue Book here on the SEAONC Hensolt Legacy Page: https://lnkd.in/gq_qZajz

As our wetlands dry up, I can see this being a valid argument.

In today's globalized world, the importance of internationalization in the field of natural disaster management #trumerschutzbauten and climate change #nagema cannot be overstated. As our planet faces increasingly frequent and severe natural disasters, and the impacts of climate change become more pronounced, it has become imperative for companies operating in this sector to expand their reach beyond national borders. Internationalization offers several key benefits for companies in the field of natural disaster management and climate change. #INTERPRAEVENT2024 #Naturgefahrenrisikomanagements #nagema #trumerschutzbauten
