Abstract
This study explores the insights of professionals within the building industry concerning the causes and structural implications of cracks in buildings. In many rural regions, buildings are predominantly constructed using load-bearing wall systems. These systems typically consist of masonry walls arranged at regular intervals to transfer gravity loads directly to the foundation, without the use of reinforced concrete columns. The research methodology comprises two main phases: the first involves on-site inspections and field surveys, while the second includes a parametric analysis of observed patterns. Primary data were collected through structured questionnaires administered to experienced professionals actively engaged in construction practices. The findings indicate that residential buildings in the studied areas are frequently constructed at or near ground level and often lack rigid tie-beams beneath the walls essential component for resisting differential settlement. Four principal categories of cracks were identified in the surveyed buildings: settlement-induced cracks, thermal expansion and contraction cracks, cracks arising from inadequate structural design, and cracks due to overloading. These defects were found to critically compromise the structural integrity and serviceability of the affected buildings. Additionally, the presence of openings in load-bearing walls was shown to significantly reduce wall stiffness, thereby lowering the failure load threshold and increasing deflection, which can result in premature structural failure. The study concludes that the incidence of such cracks can be mitigated by implementing appropriate construction practices, selecting high-quality materials, minimizing design errors, and adhering strictly to relevant building codes and standards.
