The U.S. Steel Tower and PPG Place are two very different buildings to look at in downtown Pittsburgh. However, they do have one thing in common: both structures were created to showcase the materials that they were made of, which make them interesting from an engineering perspective. PPG place is rightly called “the crown jewel…
What do pasta, muscles, and a roof truss have in common? They all can be strained, although only one experiences structural engineering strain. A continuing series of articles on fundamental engineering analyses. We’ll Cross That Bridge…. Previous articles introduced the concept of stress as a fundamental engineering calculation. Another useful analysis determines the deformation, or…
Earthquake engineering is a sub-discipline of civil engineering that influences the life and property of all human beings. It is this science that has provided an in-depth knowledge of earthquakes, useful guidelines to minimize the damage due to earthquakes. Aims of Earthquake Engineering Earthquake engineering is the science of the performance of buildings and structures…
In this age of technological evolution, the field of seismic engineering has a reputation for creative thinking and advanced technology beyond conventional solutions. Seismic isolation is a fitting technology. In this section we will look at the history of base isolation how and why it works. The Earthquake Engineering Research Centre (EERC), now known as…
A variety of equipment is used for soil compaction. A road roller is one of the main items of equipment in this category that is used extensively for road construction. A road grader is also used in combination with the road roller for soil leveling. When is Soil Compaction Required? There are numerous requirements where it…
Soil is formed in layers due to the physical, chemical, and biological processes that include transformation of soil materials. Soil mechanics is basically the study of soil and its properties in regard to construction purposes. What is Soil Mechanics? Soil mechanics is a discipline of civil engineering that predicts the soil performance characteristics utilizing the…
Ever hit a pothole at 70mph? To paraphrase Ben Franklin, do a little preventive work now and save a lot of curative work later. Applied to roads and highways, this philosophy is increasingly important in light of changes in infrastructure budgets. Expecting the Unexpected Anyone who drives a road vehicle knows how vital a good…
A continuing series of articles on fundamental structural engineering analyses. In this article the tensile and compressive stress in structural elements is examined. Since this determination is usually not trivial, computational tools and models provide invaluable analytical insight. Tension and Compression Taoist Balance A previous article introduced the moment of force as a useful engineering…
Sand making is important for the construction industry, foundry, and other applications. Sand is produced by a sand making plant that is a complex structure with crushers for crushing materials to the desired size. The sand size produced will be dependent upon the sand application. Sand Basics The most widespread sand ingredient is silica, also…
Life is precious, and should not be wasted by road accidents. Use of the road safety features and proper driving may prevent road accidents. The roads have been designed keeping in view the human factors in road safety. Safety posters and slogans can influence humans towards safe driving. Importance Of Road Safety Risks will always exist that…
