    Recent Advances in Structural Engineering—An Introduction
    (Springer Science and Business Media Deutschland GmbH, 2024) Sreekeshava, K.S.; Kolathayar, S.; Vinod Chandra Menon, N.; Bhargavi, C.
    This comprehensive overview explores recent advances in structural engineering with a focus on sustainability, resilience and performance evaluation of structural members. In the contemporary construction landscape, where environmental concerns and resource limitations significantly influence design practices, the integration of sustainability principles into structural engineering has become imperative. The introductory section emphasizes the multifaceted nature of structural engineering, highlighting the critical elements contributing to sustainable and resilient designs. The analysis of design aspects is crucial, considering strength criteria, energy efficiency, occupant comfort, and minimal environmental impact. Modern structural engineers employ a diverse range of tools and techniques to create environmentally responsible designs, addressing challenges posed by evolving expectations and resource constraints. The strength criteria of structural members, such as ultimate capacity, energy absorption, axial stiffness and durability, are explored through experimental investigations on innovative materials. Studies include the combined use of metakaolin and ground granulated blast-furnace slag in concrete for marine environments, the comparison of alkali-activated concrete with conventional mortar against sulfuric acid attack and the utilization of coconut coir fibre in limestone calcined clay cement concrete. Advancements in reinforcing techniques, including glass fibre-reinforced polymers, carbon fibres and bamboo as alternative construction materials, contribute to the pursuit of sustainable building practices. The exploration extends to seismic performance, wind load analysis and the use of base isolation systems to enhance the resilience of structures. Performance evaluation of structural members encompasses diverse studies, including the behaviour of cold-formed steel tubular columns, stainless steel-reinforced concrete and the seismic response of buildings in different terrain categories. The impact of external factors such as wind, fire and temperature on structural elements is also discussed. Analysis and design aspects cover a range of topics, from the use of finite element modelling to evaluate the behaviour of hybrid composite laminates to the seismic analysis of reinforced concrete frames. The volume emphasizes the importance of progressive collapse analysis, base isolation systems and the evaluation of masonry wall safety. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

    Recent Advances in Building Materials and Technologies–An Introduction
    (Springer Science and Business Media Deutschland GmbH, 2024) Kolathayar, S.; Sreekeshava, K.S.; Vinod Chandra Menon, N.; Shekhawat, P.; Bhargavi, C.
    This volume underscores the critical influence of building materials on construction projects, emphasizing their role in progress, quality, and operational durability. The construction industry's explosive growth, aligning with economic development, is noted as a positive force for industrialization and modernization. Amidst climate change considerations, the imperative for sustainable and resilient building materials is highlighted. Alternative materials, whether fully or partially replacing aggregates or cement, emerge as vital for sustainable and resilient construction. These include diverse industrial wastes (e.g., plastics, construction by-products) and fibers/ashes (e.g., jute, steel, sugarcane bagasse). A notable innovation is the geopolymer, an alkali-activated binder offering superior durability and mechanical strength with lower energy consumption and CO2 emissions than traditional cement. In waste material utilization, studies explore plastic, waste tea, scrap ceramic tiles, and construction waste in concrete, addressing both sustainable waste management and high-performance structures. Ash applications consider wood ash, palm oil fuel ash, and agricultural waste ashes as sustainable alternatives to traditional cement. Geopolymer advancements encompass mechanical behavior, heat conditions, and novel applications like using iron ore tailings. Durability assessment explores nanotechnology to enhance concrete properties and reduce energy consumption. Fiber-reinforced materials and compressed stabilized earth blocks reinforced with coconut fiber aim for enhanced mechanical properties and reduced carbon emissions. The volume also touches on construction project investigations, addressing safety, progress tracking, and construction delay analysis techniques. In essence, this synthesis offers a panoramic view of recent advances in building materials and technologies, contributing to a holistic understanding of sustainable and resilient construction practices. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.
