Strain gauges

are used to monitor deformation and stress in structural elements such as beams, columns, walls, or foundations. This technique helps engineers evaluate the actual load behavior and performance of materials under real conditions.

How it works

Strain gauges are precise sensors attached to the surface of a structure or embedded within it. They measure micro-deformations caused by stress or load. The data can be read manually or continuously monitored using a data acquisition system.

Sensor placement

Strain gauges are strategically installed on critical structural elements.

Calibration and testing

All sensors are verified for precision and proper connection.

Measurement and monitoring

Strains are measured during specific load conditions or continuously over time.

Data analysis

Results are interpreted to evaluate internal forces, safety margins, and material behavior.

Process steps

Used during construction, testing phases, or long-term monitoring of existing structures.

Identify measurement zones

Critical stress areas

Engineers select key structural elements where monitoring is required.

Install strain gauges

Accurate placement

Sensors are glued or welded to surfaces or embedded in concrete elements.

Connect acquisition system

Data logging setup

Wires or wireless systems transmit readings to a central unit.

Record and evaluate

Real stress insight

Data is collected, visualized, and used to verify design assumptions or identify risks.

Benefits

High-precision stress monitoring

Detects even minimal strain changes in materials and joints.

Real-time data acquisition

Enables live monitoring during tests, construction, or operation

Structural safety validation

Confirms if stress levels remain within designed safety limits.

Suitable for various materials

Works on steel, concrete, composites, and more.

Where it applies

Frequently Asked Questions

What is the typical resolution of a strain gauge system?

Modern systems can detect strain changes as small as 1 microstrain (με).

Can strain gauges be used permanently in structures?

Yes — long-term monitoring is possible with durable installation and weatherproofing.
