Incorporating the formation mechanism of wind pressure pulse events, the peak over threshold method was employed to study properties of this kind of events. The event duration time, the energy contribution, the number of the pulse events, and the distribution of average peak pressure were calculated. Probability density functions of some typical samples in separation region were also given. Results show that the non-Gaussian roof pressure is strong in the flow separation region owing to the wind pressure pulse events. Evaluations of the extreme peak pressures, which can be determined by the peak over threshold method effectively, are important to the design of building cladding.展开更多

The flexibility of the room in traditional Turkish house is characterized with its fixed-in-furniture, which supplies all necessities of a person in a house. This paper will discuss the similarities and differences in use of space between traditional Turkish houses and today＇s flats in apartments. The comprehensions will be made through the field works on traditional houses and with the projects of architecture students in Mimar Sinan Fine Arts University, Istanhul. The concept of the students＇ projects is redesigning their own houses. Since the students come from different regions of Turkey, their houses have both similar and different spatial characteristics. Whether the cultural identity of the user plays a role in use of living space will be discussed. The aim of this study is to put the relation between the past and today＇s use of interior spaces of Turkish houses.展开更多
