New NIST publication series addresses design of earthquake-resistant structuresSeptember 05, 2008Where can you find some of the latest insights in designing earthquake-resistant buildings joined together with current information on building codes? As part of its support for the National Earthquake Hazards Reduction Program (NEHRP), the National Institute of Standards and Technology (NIST) has released a publication that provides guidelines for designing a special type of structural frame used in regions with high seismic activity.* The new NIST publication is the first of a special series of "techbriefs" intended to address topics of interest to earthquake professionals in the design and construction industries. NIST anticipates issuing one to three such briefs each year. Technical Brief No. 1 describes the design of concrete-reinforced "special moment frames," structural systems that consist of beams and columns with connections that transmit bending forces (moments) from the beams to columns and vice versa. The term "special" is used in the structural engineering community and model building codes to denote systems that are designed and detailed for use in geographic areas where seismic effects can be large. The document provides design guidance by combining what is required by building codes with knowledge gained in recent research and design practice. The Applied Technology Council (ATC) and the Consortium of Universities for Research in Earthquake Engineering (CUREE) are partners in the joint venture, with which NIST has a five-year research contract.

Building energy efficiency programs in Europe and Australia The United States can become more energy efficient and create more "green" jobs by adopting some of the strategies used by the European Union and Australia to rate and disclose the performance of commercial and government-owned buildings, according to a new RAND Corporation study issued today. Health experts offer action steps local governments can use to cut childhood obesity rates Zoning restrictions on fast-food restaurants near schools and playgrounds, community policing to improve safety around public recreational sites, requirements that publicly run after-school programs limit video game and TV time, and taxes on high-calorie, low-nutrient foods and drinks are some of the strategies local government officials can use to tackle the childhood obesity epidemic in their communities. The impact of 1989 Loma Prieta Earthquake -- 20 years later The Loma Prieta earthquake transformed the earthquake sciences and engineering and remains a major focus of study, some twenty years later. The 17 October 1989 magnitude 6.9 Loma Prieta earthquake severely shook the San Francisco and Monterey Bay regions and initiated major changes in earthquake science and engineering, disaster response and public policy well beyond California. Straw bale house survives violent shaking at earthquake lab It huffed and puffed, but the 82-ton-force, earthquake-simulation shake table could not knock down the straw house designed and built by University of Nevada, Reno alumna and civil engineer Darcey Donovan. Why California should consider Australia's 'prepare, stay and defend' wildfire policy Even as debate rages over the safety of Australia's "Prepare, stay and defend, or leave early" policy of wildfire defense, fire researchers at the University of California, Berkeley, and in Australia say that the strategy is worth consideration in California and other regions in the United States. Simple method strengthens schools, other buildings against earthquakes Civil engineers using a specialized laboratory at Purdue University have demonstrated the effectiveness of a simple, inexpensive method to strengthen buildings that have a flaw making them dangerously vulnerable to earthquakes. Most US organizations not adapting to climate change Organizations in the United States that are at the highest risk of sustaining damage from climate change are not adapting enough to the dangers posed by rising temperatures, according to a Yale report. Earthquakes may endanger New York more than thought, says study A study by a group of prominent seismologists suggests that a pattern of subtle but active faults makes the risk of earthquakes to the New York City area substantially greater than formerly believed. Supercomputer Unleashes Virtual 9.0 Megaquake in Pacific Northwest On January 26, 1700, at about 9 p.m. local time, the Juan de Fuca plate beneath the ocean in the Pacific Northwest suddenly moved, slipping some 60 feet eastward beneath the North American plate in a monster quake of approximately magnitude 9, setting in motion large tsunamis that struck the coast of North America and traveled to the shores of Japan.
