M2M Remote Monitoring System

Structural Health Monitoring (SHM)

Why SHM?

• Public safety, Protect Owner Property & Investment

• Help on infrastructure planning a decision making

SHM Approach

• System Identi!cation Geometry, Boundary conditions &

Material properties

• Live load identi!cation Current loading and Loading history?

• Finite Element Modelling (FEM)

• Determination of limit states Strength, De"ection & Fatigue

What SHM can achieve?

• Analysis of structural integrity

• Damage detection

• Analysis of aging and useful life

• Behavior under new loadings

• Help to provide solution for the potential problems

• Help to protect historical structure

System used:

• Proven SysEng Mission Critical Real Time Monitoring

& Alert system used in Singapore since 2001

• Sensors are measured and processed every 10

minutes and available in the secured website using

Machine to Machine Technologies (M2M)

• 300 MEMs Tilt sensors for structure movements

• 400 VW Strain Gages and 400 Temperatures for

cast-in, Post-tensioning and strut monitoring

• System handles 158,400 sensor readings per day
