Strain and Deflection

Project Description

Summary: Roof structure deflection monitoring combining MuST fiber optic strain and temperature sensors with 3DeMoN ROBOVEC optical distance measurements

Clients: McDonnel

Place: Halifax (Canada)

Period: 2006 - 2006

Installation: McDonnel / SMARTEC

Structure's short description: Halifax Metro Centre has become a first class multi-entertainment, sports facility and exhibition centre connected to the World Trade and Convention Centre, in a strategic downtown location at the centre of metro business activity. It is the largest arena in Halifax and is host to a range of entertainment and sporting events in the city. It currently has a seating capacity of 10,595 for ice hockey. Since the arena?s construction in the late 1970s

Aim of monitoring: The main aim of the project is to measure and monitor in quasi real-time the deflection of the roof's structure caused by extraordinary events such as heavy snowfalls or punctual events happening inside the arena (e.g. concerts) and requiring heavy equipment to be hanged on the roof's trusses.

Number of sensor: 36

Main Results: N/A
