Overtaking the wood truss as a popular choice for structural design, the steel truss has become an important architectural and structural engineering element. Cold forming into curvilinear engineered steel trusses creates an astounding variety of architectural design. History And Types Of Steel Trusses As a relatively new building material, steel has become especially useful when incorporated into…
Computer models are useful in structural analysis, but are no substitute for laboratory testing. An important facet of structural testing and design, field and laboratory evaluation of engineering materials provides invaluable design and forensic information for structural engineers. The Need For Structural Testing In this age of computer modeling and analysis one might begin to think that structural testing…
Tedious hand calculations and slide rules for structural engineering design and analysis has given way to a plethora of low cost or even free structural engineering design software. A few example links are listed for convenience. The Evolution of Structural Engineering Design Software It wasn’t too long ago that structural engineering design calculations were performed…
Bridges have been constructed since ancient times. Simple bridges constructed from felled trees have been improved upon modern ones constructed by the modern light and strong materials. The latest computer technologies have significantly facilitated bridge design and bridge construction. History Of Bridges Bridge study has revealed that people have been carrying out bridge construction since humans first…
Bridge construction has been improved tremendously with the advancement in science and technology. Better and lighter materials are now available that can endure greater loads. The construction is now much faster due to the introduction of a variety of heavy construction equipment. Bridge Construction Planning Bridge construction tends to involve huge projects that encompass the…
Noise pollution is caused by unwanted sounds that intrude into our daily lives. The increasing density in urban planning has made it essential to deal with this problem. Noise is a pollutant that is controllable and is amenable to abatement technology. Standards have been set out by the Environmental Protection Agency which sets the standards…
Preliminary use of water chlorination took place in the mid to late 1800’s. The history of water chlorination for regular disinfection of public water supplies, however, began in the U.S. early in the 20th century and led to a dramatic drop in the incidence of the major waterborne diseases. Impact of Water Chlorination The use…

Pressure valves in the Chunnel involve an important design concept. The designers of the Chunnel have optimized the air dynamics inside the tunnel so that passengers inside a train feel almost no effect due to pressure changes. How did they achieve this feat? What is the Channel Tunnel? The Channel Tunnel, which is popularly known…
The Seikan Tunnel is one of the best examples of engineering. Its construction process provided useful technologies that have been used worldwide. Introduction The idea of building the Seikan Tunnel was introduced before the Second World War, but the actual investigation about building the tunnel was started after the war. The requirement of Seikan Tunnel…
