Project Abstract

This research presents an integrated assessment of seismic retrofit strategies and advanced materials for improving the resilience of civil infrastructure in high-risk seismic zones, with emphasis on existing reinforced concrete (RC) buildings, soft-soil foundations, and urban drainage networks. The study evaluates retrofit techniques ranging from base isolation, viscous dampers, and fiber-reinforced polymer (FRP) strengthening to masonry retrofit methods, underpinned by performance-based design (PBD) criteria and life-cycle considerations. A parallel stream investigates ground improvement techniques for soft soils, including vibro-compaction, cementitious grouting, and geosynthetic-reinforced soil (GRS) systems, quantified through centroidal evaluations of stiffness, settlement, and liquefaction resistance under representative earthquake demand histories. Sustainable concrete formulations incorporating industrial by-products (fly ash, slag, silica fume) are developed and tested for workability, durability, and low-carbon performance, with parallel geopolymer candidates evaluated for masonry and block applications. A Smart Bridge Monitoring System (SBMS) leveraging wireless sensor networks (WSNs), edge computing, and data analytics is deployed to capture real-time structural responses, enabling early warning, health monitoring, and predictive maintenance across bridge decks and pylons. Flood-resilient urban drainage designs are formulated using pervious pavements, storage units, and green-blue infra- structure that harmonizes with microclimate control, while life-cycle assessment compares RC versus timber deck options for rural bridges to identify optimal material pathways. The research also explores optimization of retrofitting methods for historic and modern masonry buildings to meet updated seismic codes, and evaluates fly ash-based geopolymer masonry blocks for sustainable construction efficiency. Urban canal embankments are stabilized through geosynthetic reinforcement and lightweight fill strategies to mitigate scour and overtopping risks, complemented by 3D-printed cementitious components for rapid temporary works. Pervious concrete performance under traffic loading and stormwater infiltration is assessed to optimize urban drainage and water quality. Additional strands investigate accelerated curing regimes for hot climates to ensure early strength gain without compromising durability, and the behavior of basalt fiber-reinforced polymer (BFRP) bars in heated fire scenarios to establish safe design limits. Rehabilitation of dam spillways with hybrid concrete-cear-stone linings is modeled to extend service life under multi-hazard sequences. Numerical modeling of tall-building wind-induced vibrations with tuned mass dampers informs retrofit strategies for tall RC frames, while salt-affected soils and soil–structure interaction phenomena in deep foundations are studied to refine foundation design under climate-driven soil moisture fluctuations. The integrated framework combines experimental tests, field data from SBMS deployments, and numerical simulations to deliver actionable guidelines for retrofit prioritization, material selection, and performance verification that advance resilient practice across seismic, hydrological, and environmental domains.
