Rammed Earth (RE) is enjoying a renewed interest in North America. Contemporary stabilized rammed earth (SRE) builds upon traditional RE and incorporates rigid insulation and reinforcing steel, enhancing the structural and energy performance of the walls while satisfying current building codes. RE structures are currently engineered by licensed Structural Engineers using the Concrete Building C...

Lightweight steel-framed (LSF) construction, given its advantages, has the potential to reach high standards in energy and environmental performance of buildings, such as nearly zero-energy buildings (nZEB). When compared with traditional construction, LSF system offers distinct benefits in such fields as sustainability, cost-effectiveness, constructive process, and safety at work. Despite the ...

The collapse resulted in the media’s search for immediate answers to the following two questions; why did the bridge collapse and who is to blame? Speculative answers to the first question were proposed by the “Average Joe” and structural engineering experts alike, and involved the usual suspects; the growth from microscopic to catastrophic lengths of undetected cyclic load-induced fatigue crac...

The huge quantity of concrete is consumed by the construction industry all over the world, probably second largest after water. In India, the conventional concrete is produced by using natural sand from riverbeds as fine aggregate. Dwindling sand resources poses the environmental problem and hence government restrictions on sand quarrying resulted in scarcity and significant increase in its cos...

A first 352 Mhz CH-cavity is under construction, which will demonstrate main production steps like stem welding and galvanic copper palting of the completed stainless steel tank module

This paper describes the design of a 12-story apartment building on a single story basement, which has wood floor diaphragms, and structural steel gravity and lateral load resisting systems. The design objective was to develop the most cost-effective structural system while meeting building functionality goals and adhering to code requirements. The main structural and non-structural design issu...

We decompose factors affecting China’s energy-related air pollutant (NOx, PM2.5, and SO2) emission changes into different effects using structural decomposition analysis (SDA). We find that, from 2005 to 2012, investment increased NOx, PM2.5, and SO2 emissions by 14.04, 7.82 and 15.59 Mt respectively, and consumption increased these emissions by 11.09, 7.98, and 12.09 Mt respectively. Export an...
