    Structural Design of Rc Structures From Sustainable Development Perspective
    (01. Izmir Institute of Technology, 2023) Gültepe, Ekin; Dönmez, Cemalettin
    The growth of the population and changing demands have become a significant problem due to the limited resources of the earth. Climate change has increased the occurrence of natural events and probable disasters due to insufficient infrastructure. The economic, environmental, and social aspects of the problem necessitate sustainable practices. On the other hand, probable disaster dictates design decisions to keep the physical environment intact and resilient. Hence, the expectations from the construction industry are high. The industry also needs to tackle the task of lowering the existing high consumption levels of natural resources and energy. Being resilient under seismic events is paramount for the areas that have high seismicity. The general trend of using less material for sustainability purposes conflicts with the resilient seismic design decisions which typically cause an increase in the initial consumptions. The studies on resilience and sustainability hint that there might be design opportunities that serve both purposes together. In this study, such an opportunity for RC residential buildings is focused. The resilience and energy cost of a conventional moment-resisting frame and the same frame with increased robustness through the addition of shear walls are studied. It is presumed in addition to the increased robustness, the thermal impact of the additional concrete mass will create an advantage for energy consumption in the life cycle of the building. The design decision for shear walls is based on the proposal by Hassan and Sozen (1997). Nonlinear time history analysis is performed for both frames according to Turkish Earthquake Regulation. Results show that the robust frame has the needed resilience. The energy analysis shows that the frame with shear walls has significantly higher consumption initially. However, when the thermal impact of the concrete is included in the full life cycle, the energy consumption difference reduces from 18% to 4%. As a result, it could be stated that providing sufficient robustness to the structure by shear walls at targeted locations provides an opportunity to have a resilient and sustainable structure with a minor increase in total energy cost throughout the life cycle of the structure.

    A Research on Structural Design Approaches Within the Scope of Theory and Application
    (Izmir Institute of Technology, 1998) Korkmaz, Koray; Eyüce, Özen
    The integration of creative, imaginative and economically feasible structures into the design process of _buildings has always been an essential issue in the history of architecture. The aim of this study is; to explore the relationship between the design of structural systems and the formation of architectural space, to display the changes in structure/space relationship in respect to scientific progress from the beginning of the age of positivism until today. This study is structured in two parts. At first, a morphological classification is made within a retrospective overview to explore the relationship of structure and space. Secondly, the age of positivism and the effects of positivism on architectural theories are explored to determine the changes in structure/space relationship. Today, the new developments in architectural space concept, such as "dynamic stability" affects the design of structures. Still, it is clear that the structure is an indispensable necessity during the process of shaping the space and architectural end product "building", whether the space is static or dynamic.

    A Research on a Reconfigurable Hypar Structure for Architectural Applications
    (Izmir Institute of Technology, 2013) Susam, Gözde; Korkmaz, Koray; Korkmaz, Koray
    Kinetic design strategy is a way to obtain remarkable applications in architecture. These kinetic designs can offer more advantages compared to conventional ones. Basic knowledge of different disciplines is necessary to generate kinetic designs. In other words, interdisciplinary studies are critical. Therefore, architect's knowledge must be wide-ranging in order to increase novel design approaches and applications. The resulting rich hybrid products increase the potential of the disciplines individually. Research on kinetic structures shows that the majority of kinetic structures are deployable. However, deployable structures can only be transformed from a closed compact configuration to a predetermined expanded form. The motivation of the present dissertation is generating a novel 2 DOF 8R reconfigurable structure which can meet different hyperbolic paraboloid surfaces for architectural applications. In order to obtain this novel structure; the integration between the mechanism science and architecture is essential. The term reconfigurable will be used in the present dissertation to describe deployable structures with various configurations. The novel reconfigurable design utilizes the overconstrained Bennett linkage and the production principals of ruled surfaces. The dissertation begins with a brief summary of deployable structures to show their shortcomings and their lack of form flexibility. Afterward, curved surfaces, basic terms in mechanisms and overconstrained mechanisms were investigated. Finally, a proposed novel mechanism which is inspired from the basic design principles of Bennett linkage and the fundamentals of ruled surfaces are explained with the help of kinematic diagrams and models.

    The Assessment of a New Relationship Between From and Structure in Digital Architectural Design Affter 1990's
    (Izmir Institute of Technology, 2013) Demir, Yelin; İnceköse, Ülkü
    From the beginning of 1960’s, architects are using computers in architectural design processes. Initially, architects used them as design tools for representation and modelling purposes. However from the beginning of 1990’s, architects started to use computers as design mediums where the whole design process evolves starting from design ideation to construction. Digital technologies enabled architects to design wide range of forms in digital design environments and therefore, form-based design processes appeared. Architects mostly focused on form generation concerns. However, this form based approach brought forth problems in relation to constructability. Complex irregular forms challenged engineers to find optimal structural solutions. Architects and engineers started to work on a unified architectural and structural design process and offered new structural system solutions with the help of digital technologies for overcoming the constructability problem. This process and solutions presented different form-structure relationships. The main aim of this thesis is to reveal the form-structure relationships in digital design processes focusing on constructability of digitally designed forms. Constructability is related to structural system design. Therefore, this thesis examines design, manufacturing and construction processes of structural systems to understand how architectural designs/forms are realized and constructed. It examines the whole process of design to construction of structural systems including models, tools, structural system solutions, and fabrication and construction methods. The examination is done over case studies which are digitally designed and constructed building examples. Each case study exemplifies a different model, tool, structural system and design process which also defines a different type of form-structure relationship. Key words: digital architectural design, structural design, form, structure, construction
