WHEN:  Monday, December 5, 11am-1pm WHERE: Central Connecticut State University at Nicolaus Copernicus Hall Room 157 Wireless Sensor Network on Civil Structures This presentation will discuss the first and the largest wireless sensor deployment case on a large suspension bridge. Long span bridges must endure the strong wind load, heavy trucks, and trailers. Thus it is very important to constantly monitor the structural health of the bridge. Traditionally, accelerometers and strain gages are installed on the bridge with the long line of fiber optic cables to the management office. The advantages of wireless sensors over wireless sensors are that they are easy to add, remove, and relocate on difference places on the bridge. ZigBee (IEEEE 802.15.4) was used for short-distance communication and CDMA was used for the data transferring to the server in the management office which is at remote location. Bio of the presenter Dr. Andy Chae is a civil engineer and a professor at CCSU in the department of Construction Management. He has over 15 years of experience in IT application in construction engineering management. His main research areas are monitoring of civil and building facilities with sensor network, 3D scanning and modeling for construction project, and machine learning and automated construction robots.
