This book presents select proceedings of the International Conference on Sustainable Infrastructure: Innovations, Challenges and Opportunities 2023 (SIIOC 2023). The topics covered include behavior of masonry and RC buildings under earthquakes, performance of concrete, bricks and blocks manufactured with non-organic industrial wastes, bamboo for construction, composites for construction, and finite element simulations on buildings and special structures. The book presents various facets of experiments to characterize the properties of construction materials and intricacies involved in performing finite element simulations to assess the behavior of buildings under seismic and wind loading conditions. The book serves as a resource material for budding researchers and industry professionals interested in developing solutions for sustainable building habitats.
