Abstract:
1. A structural joint strain monitoring system comprising: jacket means for receiving a T-shaped joint between hollow structural members to be monitored, the jacket means comprising a T-shaped jacket element of a complimentary size and shape for enclosing at least part of the joint to be received and fixing means for fixing the jacket element in position around the at least part of the joint, the jacket element comprising primary and secondary hemi-cylindrical parts, the secondary part extending generally perpendicularly from the primary part, and at least one web element extending between the first and second hemi-cylindrical parts; and at least one optical fibre strain sensor mechanically coupled to the jacket element at a measurement location, said optical fiber strain sensor configured to be optically coupled to an optical fiber strain sensor interrogation apparatus.
