Mr. Tucker performs initial scan of the 4th floor of the signature engineering building. Below you can see a video of his work.
First set of data is taken with the new mount deign and PCB donated accelerometers. The data appears to be very sensitive to activities in the building. Careful analysis reveals that a sensor mounted on the 4th floor for a trial run can detect motion on other floors, as well as vehicle movement near the vicinity of the building. More details to come.
After much consideration a simple, but sturdy mount that will meet all our instrumentation and building installation needs is designed. The mount will be long enough to satisfy fire code and fire proofing requirements as well as stiff enough to not interfere with the sensor measurements. The simple design also allows for ease of manufacturing and installation. The mounts will be welded to the steel frame of the SEB. Each mount will be able to support up to five sensors. The current plan is to outfit each mount with either 1-, 2-, or 3-axis of accelerometer channels depending on location. Special thanks to Dr. Tony Shakal and Dr. Moh Huang of the California Department of Conservancy, California Strong Motion Instrumentation Program (CSMIP) for sharing their insights and experience and for helping us come up with an appropriate mount design. The Virginia Tech Student Engineering Council (SEC) grants funds to VT SIL for the instrumentation of the SEB through the 2013 Big Contribution Fund! Thank you SEC! The second round of testing was much more extensive. We learned a lot of things this time around. Many of which were mistake-driven. First initial tests are carried out at the signature engineering building. Gilbane was nice enough to let us walk around and give us a guide to help us. Little did we know what we were into! Thanks to Gilbane! David Childress and Eric Hotek |
