The use of digital image correlation for identifying failure characteristics of cross-laminated timber under transverse loading

Abstract

The localised crack induced by external load on an individual cross laminated timber (CLT) structural element will generate stress concentrations, which leads to the failure of a structural member. A better understanding of the structural performance of CLT in terms of its strength and failure modes under transverse loading needs to be developed to ensure structural stability, safety and resilience of mass timber buildings. The monitoring and prediction of crack initiation and the failure modes of structural elements before and after localised deformation could enable the mitigation of severe damage in timber buildings. In this study, four-point bending tests were conducted and the digital i..
