Are Buildings As Safe As They Seem

Are big buildings as safe as they seem?

Introduction

This essay is about finding out I big buildings are as safe as they seem, the aim of this essay is to do an investigation to find out whydid the Tacoma Narrows bridge fell from the point of view of Physics and Science?, what went wrong?, what was the cost of those mistakes?, what factors must be taken into consideration before making abig building and why? What makes the difference between a safe and a non-safe building? My research is based from a scientific view to give a more precise conclusion. I will be investigating about thestructure of buildings and which structure is the most safe for building and to stand an earthquake or any natural disaster.
This topic is important because this is talking about something thatshould concern us all because by this essay I will be able to know which buildings are safe and which not, also this could help to solve all the deaths that happen when there are earthquakes because if weinform the people and maybe put some pressure for them to move to a more secure building, this could decrease the number of deaths significantly; most of the deaths in earthquakes are caused by a badconstructed building falling and not the earthquake itself.

There some theories on why did the Tacoma Narrows bridge fell so drastically, I will mention the more important. One of them isthat the winds were just to strong and caused the big bridge to do a torsion movement. The other one is called the “Random Turbulence”; this means simply that the winds excited the natural frequenciesof the bridge. This condition is called “Resonance”. The construction of the first Tacoma Narrow bridge cost was over 6 million dollars, and the construction of the bridge that would replace theTacoma Narrow Bridge cost was over 7 million dollars, adding up this to number will give over 13 million dollars which in my opinion is a very high amount of money spent because of a failure.
