Stay-cable response
Bridge Cable Tension Monitoring
Strain sensing at cable and anchorage zones provides a record of how tension changes under operational loading.
- Cable force
- Strain response
Applications & case studies
Bridge monitoring, shown through field context.
These references focus on what was measured, where the sensing line was placed and how the resulting spatial data related to structural behavior.
How to read the cases
A case is useful when it reveals the measurement boundary.
Bridge projects differ in structural form, loading and access. The relevant comparison is therefore not which project looks most impressive, but how the sensing layout followed the load path and preserved spatial meaning.
- Where
- Girder, cable, joint, reinforcement or moving structure
- What
- Strain, temperature, cable force, deformation or vibration
- Why
- Verify load transfer, detect change or support a structural decision
Field references
Five structures, five measurement contexts.

Full-lifecycle monitoring
Huajiang Canyon Bridge
Sensing arrays introduced during construction preserve a common measurement reference from erection through operation.
- Construction to operation
- Strain & temperature

Spatial strain & deformation
Jinhai Bridge Box Girder
Arrays along the bottom plate and webs capture the response of the 340 m main-span box girder as a spatial profile.
- 340 m main span
- Static & dynamic loading

Reinforcement verification
CFRP Bridge Reinforcement
Embedded or bonded fiber sensing records load transfer through strengthened zones and helps verify reinforcement behavior.
- CFRP strengthening
- Load transfer

Movement and settlement
Historic Building Relocation
Distributed measurements support controlled movement by showing how deformation develops across a structure during relocation.
- Controlled relocation
- Differential response
Evidence example
From isolated readings to a box-girder response profile.
On Jinhai Bridge, array sensing along the bottom plate and both webs made it possible to compare how different parts of the girder responded under the same loading event. The installation geometry is what gives the data structural meaning.
- 340 m
- Main-span box girder
- 3 zones
- Bottom plate and two webs
- 2 modes
- Static and dynamic loading
