Structural Strain & Stress Monitoring
(Structural Health Monitoring)

Continuous real-time monitoring of structural strain, stress, deflection, vibration and tilt in critical infrastructure — providing early warning of distress and supporting structural integrity management.

Overview

What is the Structural Strain & Stress Monitoring?

Structural Health Monitoring (SHM) uses permanently installed or temporary sensor networks to continuously measure structural responses — strain, stress, deflection, vibration, tilt, crack width and temperature — in real time. This data enables early detection of structural distress, validation of design assumptions and evidence-based maintenance planning.

Global Lab's SHM service covers sensor installation (vibrating wire strain gauges, tiltmeters, LVDTs, accelerometers), data acquisition system setup, real-time telemetry and cloud dashboard access, alert threshold setting and periodic interpretation reports. We monitor bridges, dams, tunnels, high-rise buildings and critical industrial structures across India.

Real-Time Data

Continuous strain, stress, deflection and vibration data streamed to cloud dashboard.

Wireless Telemetry

IoT-based wireless data transmission — no cable runs required on large structures.

Multi-Parameter Monitoring

Strain, tilt, deflection, vibration, crack width and temperature simultaneously.

Threshold Alerting

SMS and email alerts when monitored parameters exceed pre-set thresholds.

NABL Certified Reports

Periodic interpretation reports on NABL-accredited letterhead.

Long-Term Monitoring

Systems installed for 1 month to permanent monitoring depending on project.

Test Procedure

How the Structural Strain & Stress Monitoring is Conducted

1

Structural Assessment & Sensor Plan

Structural drawings reviewed. Critical monitoring locations identified — high-stress zones, connections, midspan, supports.
2

Sensor Installation

Vibrating wire strain gauges, tiltmeters, LVDTs and accelerometers installed at designated locations. Cables routed to data logger.
3

Data Acquisition System Setup

Data logger programmed with sampling rate, channel assignments and alarm thresholds.
4

Baseline & Live Monitoring

Baseline readings taken under known conditions. Live monitoring commenced with cloud dashboard access provided to client.
5

Periodic Report

Monthly or quarterly interpretation reports issued. Data trends, anomalies and structural assessment findings reported on NABL letterhead.
