When it comes to the precipitous decline in the reliability and efficiency of America’s infrastructure, its not just bridges we should be thinking about. The nation’s water infrastructure is falling apart, much of it tainted with heavy metals and leaking like a sieve simply due to its age.
Looking to do some building? If so, you’ve come to the right place. Referenced right here is a treasure trove of information that will help guide you through the building process, from deciding what materials to use to picking the people doing the work.You’ll also find special seismic information.
Bridges are structures that connect two land masses separated by valleys or rivers, but they serve a greater purpose as they bridge the gap between different places, cultures, and societies. Discover how civil engineers construct bridges that win out over the deepest valleys and turbulent waters.
American infrastructure is rapidly degrading. Already old and decrepit relative to other nations with developed economic systems, a looming era of budget cuts and limited investment across the board threatens to further undermine the United States’ economic competitiveness as key systems fail.
Construction of highways and railways is challenging around mountains and steep slopes. Each require special study by geologists and geotechnical engineers. Through geotechnical analysis, slopes are identified that are critical and require special protection.
Floods, rains, and other natural calamities are beyond human control. Despite advancements in technology, excessive water, and the complications it brings, always hurts social life in flood hit areas.
Street sweeping and cleaning may not look like a technical job, but it is properly carried out in an organized and planned way in the US and Great Britain.
A government in exile, a parallel government running in the mainland country, natives protesting across the globe against dictating forces, and yet Tibet manages to match its pace with the advancing technology. Science and technology in Tibet is scaling new heights.
Earlier blasts reminded us of demolitions of buildings in the US. But now, blasting reminds us of 9/11 and terrorist attacks. Post 9/11, governments have started emphasizing the need for blast containment designs that help in minimizing blast injuries.
August Wöhler, a German engineer, studied the fatigue characteristics of materials under cyclic loading. His studies resulted in development of S-N fatigue curves for shear stress. The applications of S-N curves, how to use them, and other major aspects related to Wöhler curves are focused on below.
