Purpose: The purpose of the research is to study the deformability of glass multilayer
columns at the central compression using digital image correlation. It becomes possible
to use the method of digital image correlation for the experimental study of load bearing
building structures of glass.
Design/methodology/approach: The approach which has been used to solve the above
problems is to conduct an experimental study of glass columns on central compression, in
which deformations were measured using digital image correlation.
Findings: The possibility of using load bearing building structures of glass triplex has been
discovered. A program of experimental studies was developed. It included the testing of
prototype samples on central compression with rigid fastening. On the basis of the obtained
results, a graph of dependence of relative deformations on normal tension, graphs of the
dependence of the bending of columns on load in different planes, and a modulus of
elasticity of triplex glass have been determined.
Research limitations/implications: The lack of a calculation methodology and
regulatory documents for designing load bearing building structures of triplex glass
increases their cost, since each project is individual and requires the experimental research.
Practical implications: Using the approaches developed in the paper, the method of
digital image correlation, which is to measure deformations when testing glass structures on
central compression can be applied.
Originality/value: The experimental study is probably the first one in which deformations
of glass columns are determined using the method of digital image correlation, so it is new
and original. The lack of a calculation methodology and regulatory documents for designing
load bearing building structures of triplex glass, increases their cost, since each project is
individual and requires the experimental research.
