The dynamic properties of sand-crumb rubber mixtures are pivotal in understanding their mechanical behavior and potential applications in various engineering fields. This research aims to investigate the dynamic behavior, including but not limited to shear modulus, damping ratio, and dynamic stiffness, of sand-crumb rubber mixtures under different loading conditions. By utilizing experimental testing combined with numerical modeling techniques, the study seeks to analyze the influence of varying rubber content, particle size distribution, and compaction methods on the dynamic response of these mixtures. The ultimate goal is to provide insights into optimizing the design and utilization of sand-crumb rubber composites in geotechnical and civil engineering applications, such as road construction, noise barriers, and vibration isolation systems. This research will contribute to sustainable infrastructure development by offering cost-effective and environmentally friendly solutions through the utilization of recycled rubber materials.

The seismic stability of slopes under building loads through foundations is a critical aspect of ensuring structural safety and resilience in earthquake-prone regions. 

Key objectives of this research include:

• Investigating the influence of various factors such as soil properties, slope geometry, and loading characteristics on the seismic stability of slopes as a Factor of Safety (FOS).

• For slopes subjected to footing loads, four modes of failure i.e. global, mixed, pre-local and local failure modes are observed.

• Providing practical recommendations for enhancing the seismic design and construction of foundations on slopes to mitigate potential hazards.

A set of bearing capacity factor are proposed for footing on slopes subjected to eccentric and inclined loads.

Further, this research aims to comprehensively investigate the behavior of strip footings under diverse loading conditions, with a focus on understanding the distribution of contact pressure and footing displacement on the ground surface. By examining the impacts of eccentricity, load inclination angle, and slope geometry, the study seeks to elucidate the intricate interactions between footings and underlying soil layers. Key objectives include analyzing contact pressure distribution, studying shear zone behavior, and assessing the effects of increased eccentricity on footing performance. Through a combination of experimental, theoretical, and numerical approaches, this research aims to advance our understanding of strip footing behavior and contribute to the refinement of design guidelines for foundations in sloping terrain and under eccentric loading conditions.
