Special Issue Information

Dear Colleagues,

Currently, construction methods use considerable amounts of cement, the production of which involves CO2 emission. Another environmental impact is related to the production of waste during structural repairs and especially at the demolition stage at the end of the structure life cycle. Therefore, recycling the waste presents a serious problem.

One of the ways to mitigate these environmental impacts and turn to environmentally friendly construction is to use interlocking structures, whose building blocks have specially engineered contact surfaces to maintain structural integrity. An important feature of the interlocking structures is that they can be demountable, such that after repair or demolition, some blocks can be reused.

This Special Issue invites papers that consider both classical interlocking (through keys and connectors) and topological interlocking based on the special geometry of the blocks together with the specially designed peripheral constraint. Papers considering the design of interlocking blocks, production methods, mechanics and dynamics of interlocking structures, as well as possible applications and the assessment of the environmental impact are welcome.

SiDMACIB (Structurally informed Design of Masonry Assemblages Composed of Interlocking Blocks) is the first numerical model capable of extending the equilibrium problem of limit analysis to interlocking assemblies. Adopting the concave formulation, this model can compute the stress state at the corrugated faces with orthotropic behaviour, such as their combined torsion-shear capacity. Generally speaking, finding the plastic torsion-shear capacity of planar faces shared between conventional blocks is still a fresh topic, while investigating this capacity for interlocking interfaces is particularly rather unexplored. Upon the authors’ previous works that focused on interlocking blocks with a single lock, in this paper, an extension to blocks composed of several locks (multi-lock interfaces) is presented and the SiDMACIB model is upgraded accordingly. For this purpose, the shear-torsion results obtained from the original SiDMACIB formulation are validated and subsequently compared with those derived from distinct element analysis conducted using the 3DEC 7.0 software. Based on this comparison, revisions to the SiDMACIB model are proposed, involving a reduction in the number of locks affecting torsion-shear capacity. Full article
