Focusing on soil-structure interaction, the division addresses challenges in soil dynamics, the design of foundations resistant to seismic loads, and the stability of machine foundations. This includes research on soil liquefaction, cyclic behavior, and the determination of dynamic soil properties crucial for resilient and safe infrastructure.

The division emphasizes innovative soil stabilization methods, including chemical and bio-based stabilizers for enhancing the performance of soft, expansive, and local soils. This includes the utilization of natural and synthetic materials like geogrids and bio-polymers, with a focus on sustainable and environmentally friendly ground improvement solutions.

Research in this area explores the sustainable use of industrial by-products such as Pulverized Fuel Ash (PFA) and coal combustion wastes. Studies include the characterization of these materials, leaching studies, and strategies for using recycled materials like Recycled Concrete Aggregate (RCA) for infrastructure applications, advancing both resource recovery and environmental protection.

Addressing the impact of climate change on infrastructure, this thrust area includes the development of materials and techniques to enhance infrastructure resilience against natural hazards such as earthquakes, flooding, and freeze-thaw cycles. Research also includes the application of cyclic loading tests and long-term durability assessments to evaluate material behavior under varied environmental conditions.

Integrating cutting-edge technology, the division is developing AI-driven, twin IoT-enabled systems for real-time monitoring and predictive assessment of geotechnical infrastructure. This includes creating frameworks that provide continuous insights into infrastructure conditions, aiding in proactive maintenance and risk mitigation.

The division also prioritizes the characterization of soils and recycled materials, investigating properties such as thermal, electrical, and resilient modulus. Advanced laboratory and field testing methods are used to assess the liquefaction potential, mechanical properties, and long-term performance of soils and stabilized materials, providing critical data for safe and efficient design practices.
