Shake, Rattle, No Roll: New Guide for Quake-Resistant Buildings

31.07.2009
A guide* for designing buildings using steel moment frames to resist earthquakes has been published by the National Institute of Standards and Technology (NIST) as part of its support for the National Earthquake Hazards Reduction Program (NEHRP).

Beams, columns and beam-column connections are specially designed in “structural steel special moment frames” to withstand building sway during the ground shaking that accompanies earthquakes.

The new publication, "Seismic Design of Steel Special Moment Frames: A Guide for Practicing Engineers," consolidates requirements of the International Building Code, which is the code generally adopted throughout the United States, and related standards including ASCE 7, AISC 341 and AISC 358.

The guide covers code requirements and accepted approaches to their implementation, including background and sketches to illustrate the requirements. It also includes chapters on the use of special moment frames, their principles, guidance on analysis and design, additional requirements and detailing and constructability issues. The authors, professional engineers Ronald O. Hamburger, Helmut Krawinkler, James O. Malley and Scott M. Adan, also present best practice recommendations for design and construction that may not be specifically required by the codes or standards.

"Seismic Design of Steel Special Moment Frames: A Guide for Practicing Engineers" is written for structural engineers, building officials, educators and students. It is the second in a series of technical briefs that NIST is publishing to address topics of interest to earthquake professionals, primarily those in the design and construction industries. Future technical briefs are expected to cover performing nonlinear structural analyses and seismic analysis and design of reinforced concrete diaphragms.

The guide is available at www.nehrp.gov/pdf/nistgcr9-917-3.pdf.

Im Focus: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
