- Description
- This work reports the results of an experimental campaign on a type of dry jointed and prestressed masonry. The
campaign is part of a larger project with the main objective of to develop an innovative wall construction system
for economical dwelling in seismic prone areas of underdeveloped countries. The campaign tested 12 stack bond
prisms and 6 regular bond prisms, in order to measure the strength and Young modulus of the material under
axial compression and to observe the failure modes. Six wallets, postensioned in the head joints direction were
tested in order to determine the diagonal compression strength, the shear modulus, and to observe the failure
mode. Under these simple tests, the proposed material behaves adequately; in particular, the shear failure mode
presents a very large displacement capacity.
