Pressurized sand damper proposed for earthquake engineering

Earthquake shaking has resulted in severe damage of structures built in the past 40 years, despite being designed according to building codes valid at the time of construction. Seismic displacement has been identified as the cause, and over the past four decades many seismic and wind engineering design and retrofit strategies have been employed. One such strategy is the addition of fluid dampers to...

EMI Conference speaker’s statistical methods make the unpredictable more predictable

How can you model extreme events and predict them before they happen? One of the world’s foremost experts in probabilistic mechanics and stochastic mechanics plans to show you at the upcoming Engineering Mechanics Institute conference.

New means of improving gusset plate design’s seismic performance

Gusset plates connect weight-bearing beams and girders to columns on bridges, buildings and other structures. To minimize failure of this important connection, the connections to the beam and column must be stronger than the braces themselves. A new study in the Journal of Structural Engineering, "Incorporating Frame Action into Seismic Design of Gusset Plates" by Yao Cui, Ph.D., A.M.ASCE; Xiaozhuo Xu; Tracy C. Becker, Ph.D.,...

Researchers test sand-silt mixtures to predict liquefaction resistance

A paper in the March issue of "Journal of Geotechnical and Geoenvironmental Engineering" focuses on granular soils containing nonplastic fines (silt), investigating the combined effect of the void ratio, effective vertical stress, and fines content on the liquefaction resistance of sands.

Spotlighting seismic design criteria for nuclear facilities

Technical updates to the latest edition of ASCE/SEI 43 ensure the proper design of nuclear facilities.

Performance-based seismic design succeeds in Turkey

The design of the Başakşehir Pine and Sakura City Hospital in Istanbul, the largest base-isolated structure in the world, is the result of creative, blue-sky thinking.

Guides offer practical help with load provisions of ASCE 7-16

To assist practicing engineers, ASCE has developed supporting guides that provide detailed descriptions of the wind, seismic, tsunami, snow, and rain load provisions in ASCE 7-16.

University of California, San Diego shake table to be upgraded

The world’s largest high-performance outdoor shake table, a backbone of seismic studies, will be upgraded to move in six directions by October.

California county to benefit from temperature-phased anaerobic digestion facility

Design work is underway on a $300 million temperature-phased anaerobic digestion facility for Orange County, California. The new facility will improve biosolids quality and increase system resiliency.

AI makes quick work of earthquake damage assessment

Using aerial images from disaster scenes, a new Japanese artificial intelligence model is able to quickly evaluate building damage.
