Novel design methodologies for transfeormable doubly-ruled surface structures
(Izmir Institute of Technology, 2015) Maden, Feray; Korkmaz, Koray; Korkmaz, Koray
Today architecture seeks for adaptable spaces ever than before to meet the changing functional, spatial or environmental needs. Thus, it necessitates developing adaptive structures that are capable of geometric transformations. For this purpose, a series of kinetic structures has been developed. The most impressive examples of these structures are deployable and transformable bar structures that have the ability to change their shapes from one configuration to another. Although many innovative designs have been proposed for these structures, only a few have been constructed at full-scale due to their complex mechanical systems and limited configurations in which they can carry loads. Moreover, most of the proposed structures are restricted to certain geometric forms such as singly-curved vaults or doubly-curved synclastic domes. Doubly-curved anticlastic structures have been rarely used despite their resistance to loads through their curvatures and ease of constructing their surfaces by ruled surface generation method. The primary objective of this dissertation is to propose novel methodologies to design deployable and transformable doubly-ruled surface structures by using novel structural mechanisms (SMs) which provide morphologically flexible, mechanically simple, structurally effective and architecturally viable solutions. For this purpose, a systematic procedure is developed which comprises geometric design, structural synthesis and structural design phases. First, the geometric properties of the doubly-ruled surfaces are thoroughly analyzed and their morphologies are investigated based on the generated parametric models. Second, novel SMs are constructed by means of structural synthesis in which transformation capabilities of the proposed SMs are discussed in detail. Finally, several case studies are proposed for the architectural applications of those SMs and a set of structural analyses is carried out at different configurations of the proposed structures to discuss their structural behavior under typical loading patterns. “Simulation and modeling” has been used as the main research method in the study which covers all mathematical models and computer simulations.
A Model for Assesing Project Management Maturity Level of Architectural Design Offices (arch-Pmm)
(Izmir Institute of Technology, 2007) Beset, Doğan Arda; Günaydın, Hüsnü Murat
The aim of this dissertation is to develop a model to assess .The Project Management Maturity Level of an Architectural Design Office. (Arch-PMM). The purpose of ARCH-PMM is to develop an environment for productive and efficient design conditions. By increasing the levels of ARCH-PMM, architectural design office will create opportunity to focus on its concerns for high quality architectural design process. To determine whether Arch-PMM assessment methodology is working properly, a semi structured survey is conducted with selected architectural design offices. This study is the first attempt that focuses on architectural design offices. PM practices and processes. A 5 leveled PM Maturity Model is developed to assess architectural design offices. current PM Maturity level. Maturity levels are assessed vis a semi-structured survey. 71 Members of the Association of Turkish Independent Architects (ATIA)participated to semi-structured survey to validate the model. A list of demographical questions was asked to draw the demographical picture of the architectural design offices. Both, maturity levels and demographical data are analyzed. The results of the assessment provide the necessary information for the architects to improve their PM processes and activities. Project Integration Management was highly mature among the other function areas and it.s followed by Project Scope Management. The least matured function area was the Project Risk Management. High correlation values between the number of staff and all PM function areas are also observed. Yearly income level and overall maturity level of the architectural design offices are found to be related at correlation high levels (r.0.73). The well defined structure of architectural design process seems to support project management culture and have potentials of high project management maturity levels.
