![]() The foundation is 100 feet deep and it is surrounded by 200 circular caissons.įigure 1. It is one of the tallest buildings in the world, measuring at 1,729 feet from the bottom to the tip of its spire. An example of a foundation that hasn't failed is that of the Sears Tower in Chicago, Illinois. A building fails when it falls over or even when it starts to lean, like the Leaning Tower of Pisa. A hidden fault can cause a foundation to fail, resulting in the collapse of the building or structure. Scour is when flowing water removes supporting soil from around the foundation.Īll variables must be studied and considered when designing a foundation. The bearing capacity is the ability of the soil to support the load of the structure. These include scour and the bearing capacity of the soil. When designing the foundation, the engineer must consider several variables. There are shallow foundations and deep foundations, depending on the kind of structure and the soil. The purpose of the foundation is to transfer the load of buildings and structures to the soil. ![]() If the geotechnical engineer determines that a building can be built at a particular site, the next question is what kind of foundation is necessary. All of these variables determine if and how a structure should be built at a particular site. The engineer carefully considers the soil properties at the construction site, and takes a sample of the soil to examine many properties, including the porosity, permeability, and shear strength of the soil. Site investigations include finding out the risk to humans, property, and the environment from natural hazards such as earthquakes, landslides, and rock falls. Examples of early engineering projects include irrigation projects, dikes, and bridges.īefore a building is erected, the geotechnical engineer will perform site investigations. Humans have been using earth (or soil) for various engineering purposes since the start of civilization. The job of the geotechnical engineer is not a new one. ![]() The job of the geotechnical engineer is to understand the engineering behavior of earth materials, such as soil, and how the earth materials at a site will affect a structure being built there. More fun learning opportunities can be found in the Let’s Study Famous Folks – February Calendar.When building a skyscraper, or even a simple structure, on a slope, the team needs to include a geotechnical engineer. Compare your challenges with creating your wheel with those of the London Eye or Singapore Flyer. Or you can write an essay or a paragraph about the engineering challenges faced during the construction of either the London Eye or the Singapore Flyer. When you are finished, you can have fun with writing prompts about inventions. ![]() The Ferris wheel K’nex, and Ferris wheel Lego are definitely big hits with older students. That’s OK because these Ferris wheel STEM projects are awesome. Ok, so maybe your kids aren’t into pasta and glue anymore. Work individually or as a team to plan your wheel, execute construction, troubleshoot, evaluate your work, and present your project.ĭownload the entire Build a Big Wheel project and have fun learning about the history & architecture of the Ferris Wheel. Get ready to learn how these big wheels have been designed throughout history, and then develop a design for your own Ferris wheel made with pasta. Build a Big Wheel – Ferris wheel STEM Activity Build Your Own Wheel Grab a few engineering books at your local library for engaging science reading.
