Laboratory Testing: Steel-concrete slab

Case study: SOFO System

Steel-Concrete slabs
Interaction characterization
Shrinkage monitoring

Project Description

Summary: Steel-concrete composite slab

Clients: ICOM-EPFL

Place: Lausanne (Switzerland)

Period: 1996 - N/A

Installation: IMAC-EPFL

Structure's short description: Measurement of the deformations of a mixed steel-concrete slabs.

Aim of monitoring: The SOFO system measured the internal deformations of the concrete part at different locations during shrinkage and load test.

Number of sensor: 10

Main Results: It was possible to measure the interaction between steel and concrete during concrete setting. Different types of connectors and multiple concrete mix designs were tested. The slabs were than tested under a static load test.
