“...from various materials, for example timber, bamboo, or concrete. However, people started modifying these technical recommendations during reconstruction works without having proper knowledge on the shear bands sensitivity to these modifications. For example, during field surveys by CRAterre and 3SR in 2016 and 2017, several technical issues were observed such as the use of unseasoned timber, reinforcement bars being not properly positioned in concrete shear bands. These changes were mostly for economic reasons, but also because of a lack of properly trained masons. Hence, to find out the physical behaviour of those shear bands more experimental research work is necessary.
The mechanical impact of the shear bands has not been evaluated in the past. This is challenging as shear bands work in masonry wall and could have different impacts in depend of the masonry materials but also on the shear bands materials. The main hypothesis of the objective of a shear bands is to increase the masonry capacity...”
