Many transmission structures are tested to failure at full-scale, leading to an improved understanding of capacity compared to most structures. Typically when extreme wind events occur, the maximum ...

Washington, D.C.—The American Wood Council recently introduced four new standards, which are referenced in the 2015 International Building Code (IBC). This includes the 2015 National Design ...

Rainier Square Tower, under construction in Seattle, is one of the buildings considered for the development of a performance-based wind design manual for tall buildings. Photo Courtesy of ...

In a long-awaited, historic step toward “real" not cookbook wind engineering, the Structural Engineering Institute of the American Society of Civil Engineers recently issued a recommended alternative ...

There are several operational factors and requirements that have guided design and development of composite wind turbine blades over the last 20 years. The most important factors and requirements are ...

The National Institute of Standards and Technology (NIST) reported on Sept. 17 that it has done additional analysis of the wind "loads" that the World Trade Center (WTC) towers were originally ...

The trailing edge of wind turbine blades can be manufactured in an elastic material that makes it possible to control the shape of the trailing edge. This will reduce the considerably dynamic loads ...

“Poor conceptual designs, inherently defective structural design and poor execution of work at site, coupled with use of substandard construction material and certain bad practices of construction” ...

From all outward appearances, wind turbines are sleek and elegant works of engineering. But inside, they're hell on gears and bearings. In most turbines, the rotors turn a mechanical transmission that ...

If there were any doubts about the dangers of poorly anchored rooftop equipment during a hurricane, building consultant Thomas Lee Smith can point to case after case of flying mechanical units, ...
