Conference Object A Comparative Structural, Architectural and Cost-Based Analysis of Seismic Design Principles Applied in Reinforced Concrete Residential Buildings in Turkey(Crc Press-taylor & Francis Group, 2010) Ozmen, C.; Özmen, Cengiz; MimarlıkThis study demonstrates that it is possible to design earthquake resistant reinforced concrete residential structures without significant compromises in the spatial quality and economic viability of the building. The study addresses architects, structural engineers and private entrepreneurs who are the important players in the Turkish construction industry. In structural analyses, a set of four parametric mathematical models are used to demonstrate the effects of increased column cross-sections and use of shear-walls on the seismic performance of reinforced concrete structures. Architectural analyses are carried-out through three case-studies selected from the earthquake affected city of Bolu in Turkey. Cost-based analyses demonstrated that it is possible to design earthquake resistant reinforced concrete residential buildings with a 4-6% increase in the building cost and an economically acceptable 10% decrease in profits.Article Citation - WoS: 4Effects of Occupant Behavior on the Energy Performance of Dwellings: a Sensitivity Analysis(Locke Science Publ Co inc, 2016) Harputlugil, Gülsu; Harputlugil, Gulsu Ulukavak; Bedir, Merve; MimarlıkThis paper focuses on the influence of occupant behavior on the energy performance of dwellings in the Dutch context. The aim of this study was to identify, how the energy performance of a dwelling is sensitive to the behavior of its occupants. To this end, the study's methodology adopted the Monte Carlo method of analysis, one of the most commonly used means of analyzing the approximate distribution of possible results on the basis of probabilistic inputs. Data related to occupant behavior were generated from a survey of 313 households in The Netherlands. The Dutch reference row house was used to test the behavioral patterns, and the test results were determined through simulation-based modeling. The key input parameters were presence, heating control patterns (thermostat and radiators), and ventilation control patterns (windows, grilles, and mechanical ventilation), while minimum indoor resultant temperature and heating energy demand served as the key output parameters. The results showed that both heating energy demand and minimum indoor resultant temperature were most sensitive to the thermostat setting and most robust in relation to the radiator setting.Article Osteoporotic Ceramic Figures as a New Approach To Art and Life(Ceramic Art, 2013) Berker, Olgu; Berker, Oglu Sumengen; Ortak Dersler BölümüArticle Citation - WoS: 12The Role of Aerodynamic Modifications in the Form of Tall Buildings Against Wind Excitation(Middle East Technical Univ, 2007) Ilgin, H. Emre; Gunel, M. HalisModern tall buildings go higher and higher with the advances in structural design and high strength materials. However, every advance in height comes with a new difficulty. Efficient structural systems, high strength materials, and increased height, result with decrease in building weight and damping, and increase in slenderness. On the other hand, as the height and slenderness increase, buildings suffer from increased flexibility, which has negative effects in wind loading. Flexible structures are affected by vibration under the action of wind which cause building motion, and plays an important role in the structural and architectural designs. Understandably, contemporary tall buildings are much more vulnerable to wind excitation than their predecessors. Hence, different design methods and modifications are possible in order to ensure the functional performance of flexible structures and control the wind induced motion of tall buildings. An extremely important and effective design approach among these methods is aerodynamic modifications in architecture. In this context, the authors classify these aerodynamic modifications in architecture for resisting the lateral loads. Wind safe tall building design begins with the architect, and the influence of the wind action must be taken into consideration from the very beginning of the architectural design process by considering building aerodynamics.Conference Object The Use of Multicriteria Decision Methods in Planning and Design(int inst informatics & Systemics, 2003) Elker, CFields associated with design and physical planning are appropriate domains for the use of multicriteria decision methods. Various methods are compared and "weighted summation" technique is put forward as the most suitable method for the needs of design and planning. The case of city planning is used to illustrate the methodology. The phases of "design of alternatives", "determination of objectives and criteria" and "evaluation" are described with the help of examples. The paper concludes with principles and problems in the use of multicriteria decision methods; in design and planning.Article Citation - WoS: 5Citation - Scopus: 4Analysis of a Historic Masonry Building(Croatian Soc Civil Engineers-hsgi, 2011) Ozmen, Cengiz; Özmen, Cengiz; Akan, Asli Er; Akan, Aslı; Unay, Ali Ihsan; MimarlıkThe paper starts from the observation that historic masonry buildings are often modified and altered to make them fit for present day use. A single-family masonry house in Turkey, situated in an earthquake prone area and built in the early 20(th) century, is studied. The analysis is made based on Turkish regulations for the initial building and for the building after alterations. Introduction of a reinforced-concrete slab has greatly improved seismic resistance of the building.Article Citation - WoS: 4Citation - Scopus: 5Architect - Structural Engineer Collaboration in Sustainable Structural System Design(Gazi Univ, 2011) Ozmen, Cengiz; Özmen, Cengiz; Unay, Ali Ihsan; MimarlıkThis paper explores ways of collaboration between architects and structural engineers in the design of sustainable structural systems. Areas of collaboration are explored in terms of seismic design of new structures and rehabilitation of existing structures. Multidisciplinary design teams and an integrated design approach are critical to the process of sustainable building construction. The required group-work skills should be acquired by architects and engineers during their professional education. As a result, this paper also investigates ways in which the structural design education of architects and structural engineers can be redesigned to make their future professional collaboration more harmonious.Conference Object Conceptual Framework for a Decision-Making Model Based on the Analytic Hierarchy Process (Ahp) To Select the Best Public Private Partnership (Ppp) Model for Airports(New Zealand Acad Applied Research Ltd, 2017) Mohammed, Ali Omar; Harputlugil, Timuçin; Harputlugil, Timucin; MimarlıkThe adoption of public-private partnerships (PPPs) as a strategy for infrastructure projects, such as airports, highways, bridges, water supplies, and telecommunication, has been implemented in developed and developing countries with a number of obstacles. Based on this stance, critical success factors (CSFs) of public-private partnership projects and the selection of appropriate PPP models are critical issues that need to be analyzed. A multidisciplinary review of the literature on the critical success factors of public-private partnerships projects reveals the lack of a comprehensive decision-making model for selecting an appropriate PPP model. This paper presents a conceptual framework for a decision-making model to select the best PPP model considering CSFs for developing countries. The model is expected to be used for infrastructure projects, mostly for airports. The decision-making model is structured on the Analytic Hierarchy Process and sensitivity analysis. The decisionmaking model is expected to be adopted as a tool and contribute to decision makers for selecting the best fit PPP model for airports in order to enhance projects successfully.Review Mimarlığın Maddiliği(Middle East Technical Univ, 2020) Çavdar, Rabia Çiğdem; Cavdar, Rabia Cigdem; MimarlıkArticle Citation - WoS: 2Citation - Scopus: 1A Simple Selection Method of PV Systems for University Campuses(Gazi Univ, 2023) Harputlugil, Gülsu Ulukavak; Bara, Marıam; Ulukavak Harputlugil, GulsuThis paper briefly outlines part of the research work being carried out on the application of the photovoltaic systems to cover universities’ electrical energy needs, with due consideration to the technical, architectural, economic, social. and legal aspects and impacts of this application. The paper considers optimizing the PV system selection objectives and methodology with a case study application. at a university campus in Ankara, Turkey. The main objective here is to develop a practical simple method of selecting an optimum PV system that gives the maximum energy yield possible in a certain period of one year, with the minimum specific energy cost per kWh, where a multiple-variable multi-criteria decision-making making method is applied, to help designers and system engineers in selecting the optimum system. The developed method is demonstrated in the example of the typical case, where the recommended PV system was turned out to be at an Azmuth angle of 0 degrees, the PV technology was monocrystelline Silicon, the annual electrical energy yield per 100 m2 of PV modules surface area 22.4 MWH/Year, the specific electrical energy cost was 0.15 Euos/Kwh, as a first merit option, making a difference of around 13% of saving compared with the 10th last option. The work concludes that a viable PV application is feasible, encouraging its application in various campuses provided that comprehensive planning and careful considerations are given to the related aspects.
