In a significant advancement for the construction industry, a recent study led by Md. Foisal Haque from the Department of Civil Engineering at the International University of Business Agriculture and Technology has unveiled a groundbreaking mat-sand interaction model. This innovative approach aims to predict and control the vertical deflection of mats under varying gravity loads, a critical factor in ensuring the structural integrity of buildings and infrastructure.
The research, published in the journal ‘Discover Materials’, focuses on the interplay between mat thickness, sand elastic modulus, and imposed gravity loads. By employing finite element-based software ETABS v.18.1.1, the team conducted a linear elastic analysis that revealed noteworthy insights. “Our model demonstrates a mere 1.76% difference from previous studies, indicating a high level of accuracy when compared to field data,” Haque explained. This precision is vital for engineers tasked with designing foundations that can withstand both the weight of structures and the pressure exerted by underlying soils.
One of the pivotal findings of the study is the identification of limiting values for imposed gravity loads based on mat thickness and sand characteristics. For instance, a 150 mm thick mat can support a gravity load of up to 60 kPa, while a 200 mm mat can handle 120 kPa with a sand elastic modulus of 5 MPa. These parameters empower engineers to make informed decisions when selecting appropriate mat thicknesses and material properties, ultimately enhancing the safety and durability of construction projects.
The implications of this research extend beyond theoretical applications; they have real-world commercial impacts. By optimizing mat designs, construction firms can reduce material costs and minimize the risk of structural failures, leading to safer and more efficient building practices. As Haque noted, “This model not only aids in achieving compliance with the BNBC 2020 allowable deflection limits but also supports the economic viability of construction projects.”
Looking ahead, this innovative model may shape future developments in foundation engineering, providing a framework for more resilient structures that can adapt to varying soil conditions and loading scenarios. The construction sector stands to benefit significantly from these findings, paving the way for advancements in material science and engineering practices.
