Summary Draft 2

In the web article “I-5 and the Physics of Bridge Collapses”, Hartsfield (2013) claimed that the concept behind a functional bridge design is what leads to its failure as well. The article examined the various types of bridges and found that the different types of bridges have weaknesses specific to themselves. 

One such example stated by the article is that truss bridges, which use geometric shapes as a basis for its strength and stability. As such, it is claimed by the article that deformations on the shape will cause the bridge to fail. 

Suspension bridges fail due to its inability to withstand huge external forces. The article observed that “when an external force causes the bridge to vibrate at its resonant frequency, it causes the vibration to grow stronger and stronger”.

Another example of such phenomenon are cantilever bridges. The article alleged that cantilever bridges are designed to be able to withstand the torque that the lever arm takes, yet failures are found to be due to construction oversight and overestimation of the torque it can take.

Introduction Letter

Dear Professor Blackstone, I am writing this letter to introduce myself, my name is Derrick, I graduated from Nanyang Polytechnic in 2017 with a Diploma in Marketing, which is a course that has totally no connection with Civil Engineering. I manage to learn more about Civil Engineering upon graduation when I went to my uncle's company and to learn a little from the industry expert over there. As someone who likes to build and lead, I realize that being in the construction industry is very satisfying. It is because I can build and lead a team at the same time. As I have to lead a small team before, I know it is very difficult to make sure that everyone is well-coordinated and listens to my opinion if I did not have a strong technical knowledge in the things I do, I always believes that people will not listen to a leader that has no knowledge in what he is doing. Thus, I choose Civil Engineering not only I want to know about all the technical stuff, but I can also use my Marketin

Annotated Summary

Li, B. (2015). Geotechnical properties of biocement treated sand and clay. Doctoral thesis, Nanyang Technological University, Singapore. Retrieved from https://hdl.handle.net/10356/62560 Li Bing, associate professor of Civil and Environmental Engineering at Nanyang Technological University is the author of this investigation on the potential uses of biocement on low permeable material. This article focused on the application of biocement to improve the soil conditions for geotechnical engineering. In this research project, its aim is to use microbial technologies to study biocementation effects on low permeability materials such as clay. Microbially induced calcium carbonate precipitation (MICP) is the most practiced biocementation method. The properties of MICP treated soil were tested with various tests. For instance, unconfined compression tests, triaxial tests and direct simple shear tests. The article also mainly uses three sets of bacteria for this experiment. They are U
