MethodMixed Methods (Theoretical Modeling, Physical Experimentation, Computer Simulation)

ProcedureThe research involved developing new brick shapes (center-half bat, tee brick) and bonding patterns (Shokse, Lijuja) to enhance construction flexibility. Theoretical analysis was conducted to understand the impact of brick irregularities on alignment. Physical experiments compared different brick-laying strategies ('random', 'reversing', 'replace') and the effect of grooving on column alignment and stiffness. Computer simulations were also employed.

Paragraph starter

This research highlights the significant impact of design features on the performance of interlocking systems. The introduction of grooves near the centerlines of interlocking bricks, as demonstrated by Kintingu (2009), was found to improve wall alignment accuracy by a factor of 2.13 and stiffness by a factor of 2.0. This suggests that incorporating similar features into the design of modular components can lead to more stable and accurate constructions, enabling greater design flexibility and potentially reducing the need for additional structural support.
