Bridges are used around the world to get over a bay of water. There are several different designs that could be used when building bridges such as arc, beam , cable-stayed, truss and suspension bridges. The Golden Gate Bridge is a very well known example of a suspension bridge. It is located in San Francisco, California. Construction began in 1933, in the midst of the Great Depression, and the bridge gave steady jobs to many people during this hard time. It was finished and opened in 1937,…

There are several reasons to have a shingle roof replacement. One reason is one or several of the asphalt shingles are damaged because of a storm or high wind or aging. This type of shingle roof replacement is not replacing the entire roof but a small portion of it. The other reason for a shingle roof replacement is when the roof has aged and is no longer a functioning roof. In this case, the entire roof will have to be replaced. Asphalt is not the only material a roof shingle is made from.…

In the cockpit, all of the instruments were destroyed and all of the levers were pushed into the cockpit panel even though the throttle quadrant was damaged in the crash. However, rescue and recovery personnel were unsure if they disturbed controls and levers, and between the fire and impact damage it was inconclusive the positions of the actuators. Tracing the flight controls cables showed that the cable had the proper integrity, but burning made actuator positions indistinguishable. In the…

Climate Change and Structural Engineers The sun is the main source of energy to the planet and annually it supplies the earth with certain amount of energy. Some of this energy is reflected back to space directly, but the rest that enters the planets is either absorbed by the atmosphere and earth surface or reflected back to space. However some of the energy is trapped by the atmosphere to warm the earth’s surface in a natural way. This phenomenon is called the ‘The Greenhouse Effect’ which is…

Underestimated Risks Risk analysis in engineering design has played an important role from a very long time ago. At any certain level of designing, the understanding about the potential risk is crucial and must be carefully considered. At the last year in college, senior students will take capstone design project and learn about how to deal with risk analysis. There are many important risks needed to weigh and assess in the real world industry. These approaches should be technocratic and…

“Explain how the work of [Energy absorption in lattice structures in dynamics ] has enhanced our understanding of Structural Engineering with respect to the work that preceded it, and how this research should be developed further in the future.” Nowadays, cellular materials are well-known in the world, however, the relationship between dynamic load and the deformation of the lattice structure is less well-studied. Actually, lattice structures can help engineer to produce macro-scale material…

done by earthquakes over time cannot be over looked. The damage has been monetary, emotional, and has taken many lives. Today, a capstone in Civil Engineering, Earthquake Engineering is trying to reduce all of these damages using modern technology and resources to build structures that can withstand the mass forces of earthquakes. Earthquake engineering is broken down into two major parts, the first being understanding how earthquakes affect current structures and the types of forces they apply…

Balloon frame buildings were considered almost a universal construction method for multistory wooden buildings until the middle of the 1900’s (Corbett and Brannigan, 2015). This would have not been a problem if they would have been built with some fire resistive methods. One will discuss some of the major issues with this type of construction and some solutions and recommendations to resolve the matter. Balloon frame construction was an inexpensive and easy way to build houses, but that came…

The Johnstown, Pennsylvania flood, May 31,1889, was a tragic Disaster waiting to happen. The town was placed in a river bed for a steel company, with a poorly built dam holding a lake from pouring into the town. The town,payed to be built by Andrew Carnegie and other rich powerful men was destroyed in a instance. It would take years to repair the damage to this town. The question is, is Andrew Carnegie and other wealthy men at blame for this incident? It could have been a honest mistake or…

Abstract Cold-formed steel section (CFSS) is a civil engineering material that still and always in ongoing research for utilising in building or construction works. The advantage of the CFSS is becoming so interesting in selecting it as a roof truss system and purlins. For having the roof truss system with stable and safe condition, the study of the truss member is carried out by using the cut-curving channel section. Before the cold-formed steel section has been curved, the process of curving…
