Earthquake Test- Building Better Homes -- Improving Structural Engineering with Earthquake Simulator

Improving Structural Engineering with Earthquake Simulator January 1, 2007 — To develop designs that can survive extreme seismic events, and to devise retrofit solutions for older homes, civil engineers who specialize in structural design test realistic models of homes in earthquake simulators. They place the homes on two adjacent shake tables designed to move in three directions, creating realistic earthquake motions. Cameras and accelerometers measure the rate of movement. BUFFALO, NY -- Homes are made to withstand the test of time. But the ultimate test is one that can survive a large-scale earthquake. And simulating an earthquake in a lab helps improve homes in real quake zones. Most people don't ever want to experience an earthquake. "I experienced a very strong earthquake in 1997 in Athens," Ioannis Christovasilis, an Earthquake Structures Graduate Student at University at Buffalo in NY, tells DBIS. "I was a little bit frightened, yes." University at Buffalo Structural Engineer Andre Filiatrault says, "We had an aftershock, maybe a magnitude five ... That was pretty dicey. You felt the shaking work up." But today, Filiatrault is eager to watch an earthquake simulator shake this house to a magnitude 6.7 quake. The full-scale, fully furnished home is built like many in earthquake zones, but prone to damage. The test shows how much shaking a wood home can endure. Filiatrault says, "We shook this building past its so-called design level. We shook it to an extreme event ...

Whole Building Life Cycle Assessment - 2010 Final Presentation - Part 1/6

This is a video of the final presentation for CIVL 498C - Whole Building Life Cycle Assessment - at the University of British Columbia (UBC) Vancouver campus. This course and the study presented in this video are part of a fundamental change occuring in green building to move towards adopting more performance based assessment criteria. It is recommended for those keen to stay ahead of changing trends as an educational piece, as this course is pioneering education in LCA and it's integration into green building. Life cycle assessment (LCA) is regarded as the most comprehensive and rigorous environmental impact analysis tool available, and is the leading method for educating sustainable decision-making due to its transparent nature and un-subjective approach. Through a course conceived and taught by Rob Sianchuk, fourth year Civil Engineering students are engaged in the creation of a UBC building life cycle assessment (LCA) database. The purpose of this is to catalogue the quantified impacts of what it is to create UBC academic buildings. This includes assessing environmental impacts associated with the extraction of resources, manufacturing of construction materials, and assembly of construction materials into an academic buildings ("cradle-to-gate"). One of the primary applications of this LCA database is as an impact baseline for UBC to develop performance based green building assessment criteria upon. The primary suppporters whom have helped make this course possible ...

How to Become a Building Contractor

A building contractor is often referred to as a general contractor. Sometimes, they can also be referred to as a construction professional. Whatever they are called, to become a building contractor means being the one that takes care of house renovations, constructing buildings and roads, and being in charge of demolitions. They are the very people that provide the estimate to clients just by studying any structure's blueprints. Once a deal has been a closed and a contract is signed, contractors are the ones who will be responsible for the methods as well as the materials that are going to be used for the construction job. They are the ones who make sure that all the contract details will be met. Do you meet any of these characteristics?

To become a building contractor is far from easy. Contractors, especially those who have been in the construction business for years, have lots of equipment and materials. They usually have many suppliers and a steady flow of clients due to a great reputation. If you're a construction newbie, building a reputation can begin with a few simple steps.

1. First, you must be a people person. You should be able to communicate with persons of a different upbringing. People skills are a must because you often have to deal with clients (most of them can be demanding), your employees, and suppliers. How can you expect to be respected and known in the construction business if you're either a tyrant or a doormat?

2. Remember that before you are given any license to operate, you must fulfill certain requirements. The most basic requirements are knowledge in carpentry, landscaping, insulation, plumbing, and similar tasks. These skills are necessary and you would need at least five years of relevant contracting experience before you can be considered a professional building contractor. On top of all this, you should have mastered at least one construction skill and, preferably, a degree in construction management, construction science, or civil engineering.

3. If you think that it's too late for you to enroll in any of the degree courses mentioned, then you have to have completed at least a two-year program in construction technology or construction science. The Construction Management Association of America and The American Institute of Constructors provide certification programs to would-be building contractors. Once you have passed all their requirements and exams, then you are going to be given a certification.

4. To become a building contractor, you must also have a marketing plan in mind. You can't just go through your first contract then sit out and wait for the next. You can always utilize the power of the internet to reach potential clients. And as you slowly build your social network, you can still rely on postcards and flyers to advertise your business.

To become a building contractor is both a rewarding and a stressful experience. Your annual income could get as high as $70,000 each year but you should also make sure that you have a sound mind and a great physique which your employees and colleagues could emulate and look up to.
