Many factors caused the collapse which took place August 1, 2007 around 6:00pm with a number of fatalities. At the time of the I-35W Mississippi Bridge collapse construction workers were making additions to the 40 year old structure in hopes of separating the eastbound and westbound lanes. With the bridge being built in the 1960s there were many changes that needed to be made which put stress on the structure and girders over the course of time. With Tons of construction equipment and cars due…

h1: Structural Repair in Florida Do you have rotten beams, foundation cracks, water leaks and other foundation issues in Florida? These issues often lead to structural defects. One of the most common structural problems is wall rotation caused by expansive soils in the Florida area. Because of Florida's geological history, the surface soils that supports structures consist of clay and loose sands. Areas of the home may settle and crack due to washed out footings. Moisture…

forces can also be called 'dead' and 'live' loads. When these forces all act on a bridge at the same time it is pot under structural stress, and some parts can reach structural fatigue if too much pressure and load is placed on them for too long. Failure occurs when a member reaches its limit, and cannot support any more load, therefore breaking (Sansano, 2013). The structural elements of the Waddell a-truss bridge include two trusses, which each have compressive and tensile components. The…

On November 7th, 1940, the Tacoma Bridge collapsed into the Tacoma Narrows straight in Washington State. The bridge connected the town of Tacoma and the Kitsap Peninsula, and was one of the first major suspension bridges in the western United States. Unlike other suspension bridges constructed around this time, the Tacoma Bridge failed to withstand wind speeds over 40 miles per hour, due to unequal stress on parts of the bridge. The construction of a suspension bridge must include geometric…

5 - Critical Risk Assessment 5.1 Risk: Lack of Funding There is a high probability of a lack of funding for the Observation Tower. The impact that a lack of funding would have on the project would prevent, or delay, construction of the tower. However, a lack of funding for the tower is not critical to the other projects, except possibly the Trail Team. Factors for a lack of funding are no start-up funds and a withdrawal of donors for the tower. The plan of action for this risk is to…

Structural [A head] The structural section in the UBC – ITC Health Club Expansion project contains information primarily associated to providing structural support for the roof system and screen wall. In addition, the foundation plan shows the necessary load bearing construction for supporting these structural items. It is important to understand the details, elevations, section and other drawings to construct the building as intended. General Notes and Abbreviations [B head] The General Notes…

When your roof needs to be replaced, you want to choose a roofing material that will protect your home for the long haul without breaking the bank. The roofers at Werling Inc. in West Chester, OH, have served customers in the Greater Cincinnati area since 1974. They say that asphalt shingles provide a superior value-to-cost ratio, which is why more than 80% of homes in the United States are outfitted with them. Below, they reveal four facts about shingle roofs you should keep in mind when…

The goal of the egg drop project was to successfully create a structure that would protect an egg from a drop of three stories high. The problem resulted as an eggshell would not be strong to protect itself from a fall at this height. In this project we created a structure from common household materials, that will protect an egg from a drop at three stories high. Together, we worked hard to create a structure that is both lightweight, durable, and hopefully indestructible. To create…

also susceptible to filtering in rain and snow. While smaller spots can usually be repaired, larger ones are indicative of a structural issue with the roof. In that case, new roof installation may be recommended. You Notice It Is Sagging: If your roof appears to be sagging, it’s time to call in a residential roofing specialist for an inspection. In cases of extensive structural damage like this, a new roof is typically the only solution. You Are Constantly Replacing Shingles: A few missing…

The use of the steel frame structure in residential buildings has grown in the recent years due to the appreciation of the performance benefits, such as speed of construction, lightness of the material, safety, fire resistance, environmental benefits, such as reusability. The residential steel frame buildings, e.g. student accommodations, have benefits prior to other materials in terms of construction. Steel can be highly prefabricated, has spans of 5-7m (urban residential projects), with…
