    A study on shell structures through a comparative case study analysis
    (2023-08) Ejaz, Khawaja Talha
    Shell structures in architecture have been a topic of interest for both architects and engineers. As they do not only provide aesthetic architectural spaces but also provide efficient engineering solutions to cover larger areas. This thesis examines the historical development of shell structures and analyzes the classification of contemporary shell forms as pure shells. A comparative study of form-finding methodologies and structural systems based on fundamental shell principles is conducted, considering advancements in design techniques. The research investigates the differences in form-finding methods between historical and contemporary shell structures and their impact on design and construction. The role of auxiliary support systems in contemporary shells and their effect on classification as pure forms are explored. A categorization based on structural systems is proposed to distinguish between historical and contemporary interpretations, accounting for complexity, integration of non-shell elements, and auxiliary support systems. The analysis of structural systems focuses on load-bearing mechanisms, load paths and shell type in terms of original shell behavior in each case study. Findings highlight the shared characteristics, disparities, and patterns in form-finding methods and structural systems. The implications of deviations from historical shell principles in contemporary cases are assessed in relation to their classification as pure shell forms. Furthermore, the degree of adherence to fundamental principles is discussed. The primary objective was to gain a deeper understanding of form-finding techniques, structural systems, and functionality in shell structures over the years. Through this investigation, the research aims to determine how closely contemporary shell structures align with the fundamental principles of historical shell structures. Through an extensive literature review and examination of historical and contemporary case studies, this thesis offers a comprehensive understanding of shell structure evolution.
