Abstract
A Fundamental civil engineering knowledge is the ability
to understand, explain and calculate deformations of/in civil
structures. New civil engineers acquire this knowledge at
universities in material science, engineering mechanics and
introduction to structural engineering modules. Structural
deformations can be calculated when knowing material properties,
geometry and boundary conditions of a structure and loads
that are applied on/to it. Inverse engineering can be employed if
deformations of a structure are known, but some other parameters
are not known. Theoretical formulae are then tested using
laboratory test beds, usually beams. Laboratory technicians are
responsible for the acquisition of deformation measurements of
laboratory tests. Their time is often limited and so is the number of
available measurement collection devices such as dial gauges and
strain gauges. If devices that do not log measured deformations
are employed, information of structural deformations or response
might be lost or readings might not be collected at required
intervals. However, all laboratories do not offer luxury of sensors
that are available at hand and technicians, which would have time
to install sensorsand collect data when needed, especially if this
as to be done with a short period of notice. This paper introduces
a low-cost vision-based system for deformation estimations of
laboratory structures.
