Effect of non-uniform temperature exposure on the out-of-plane bending performance of ordinary laminated glass panels
No full textAmong the open design issues for structural laminated glass (LG) elements, their mechanical performance during fire exposure stands as a safety concern. This issue is the focus of this paper. An experimental investigation is conducted to evaluate the effect of non-uniform thermal gradients on the out-of-plane bending capacity of standard LG specimens. The pre-fracture, cracking, and post-fracture performances of LG panels were examined using a three-point bending setup. The bending tests were carried out on un-heated LG samples and heated samples, which were either hot or cooled down. The reliability of available analytical and numerical methods to predict the out-of-plane bending performance of LG is then investigated. The accuracy of the analytical and numerical methods was found to be highly affected by the non-uniform thermal boundaries, as well as by the assigned material properties, which are highly sensitive to the fire exposure
Performance-Based Design in Structural Fire Engineering
No full textThe performance-based design of structures in fire is gaining growing interest as a rational alternative to the traditionally adopted prescriptive code approach. This interest has led to its introduction in different codes and standards around the world. Although engineers widely use performance-based methods to design structural components in earthquake engineering, the adoption of such methods in fire engineering is still very limited. This Special Issue addresses this shortcoming by providing engineers with the needed knowledge and recent research activities addressing performance-based design in structural fire engineering, including the use of hotspot analysis to estimate the magnitude of risk to people and property in urban areas; simulations of the evacuation of large crowds; and the identification of fire effects on concrete, steel, and special structures

ROLE OF ARTIFICIAL LIGHTING IN EMPHASIZING THE ENTRANCE APPROACHES
No full textBuilding\u27s entrance is metaphorically a threshold between two realms, the first is an outdoor exposed to climatic change, hazards, and environmental factors, while the second is controlled, monitored, and determined to certain functions. It plays an important role in enriching users\u27 experience. Moreover, it is the first impression a visitor takes to evaluate a whole building. Architecturally, the entrance is a very special part in the elevation, distinguished and emphasized by different design approaches. One of these approaches is using lighting. There is a direct connection between recognition of a space and light assimilation in it. From sunset to dawn, the artificial lighting plays a role in drawing attention to texture, colours, and forms of external elevations, which supports architecture to achieve its purpose. This paper sheds the light on the problem of architects\u27 failure to manage an entrance perception due to insufficient light integration, over illumination, or weak transition from space to another. Many architects consider the entrance as a challenging task, because they believe that it has a direct impact on visitors\u27 perception. This paper, therefore, aims to propose design methods to emphasize the entrance of buildings at night through using the proper artificial lighting. To achieve this aim, the paper used a scientific methodology, based on tracing literature review about design of entrances, investigating ideas of entrances\u27 emphasis, and then analysing four case studies trying to identify the different design approaches of their entrances and how the location, direction, and intensity of illumination became a part of their nocturnal architectural elevation. As a conclusion, techniques of lighting entrances contribute in perceiving architecture’s true purpose and raise the aesthetic dimension of the building at night
PROBLEMS OF NEGLECTED PLACES UNDER BRIDGES: A CASE STUDY OF YEREVAN BRIDGE, BEIRUT, LEBANON
No full textArchitecture and Metaphor
No full textThis book investigates the relation between architecture and metaphor. Concept beyond architectural ideas is very important aspect for the audience of architects, students, and critics. This book considers a serious trial to uncover the secrets and intentions that generated the concepts of the 20th century architecture. From a very literary perspective, this book interprets the multiple meanings of the architectural forms, which understood as the \u27Metaphor\u27 in architecture. This book therefore deals with the phenomenon of metaphor in architecture. It produces many interpretations trying to discover the truth beyond the concepts of the 20th century architecture. It collects fifteen examples analyzing ideas of different architects and what they meant using certain metaphoric representations. This book is expected to be a reader-cum-textbook for many architectural theory classes for the next generation of architects.https://digitalcommons.bau.edu.lb/university_books/1000/thumbnail.jp
DEĞIŞEN ÇEVRESEL ETKILERE DAYALI FOTOVOLTAİK HÜCRE SICAKLIK TAHMİNİ VE PERFORMANS ANALIZI
No full textClimate change effects are on the rise due to greenhouse gas emission from the combustion of fossil fuels. The need to find alternative sustainable and renewable energy sources is of great importance. In Northern Cyprus, solar energy resources are abundant and must be utilized to provide energy security for the future and mitigate the effects of climate change. Photovoltaic (PV) solar panels are used to harness solar energy and produce electricity. The operating cell temperature of PV modules directly affects the overall performance of PV systems. Lower operating cell temperatures result in a higher module efficiency and therefore higher energy generation. Accurate estimation of the PV cell temperature is crucial to accurately assess the feasibility and economic viability of a PV power plant project. Several PV cell temperature estimation models are presented in the literature and are used in different applications for cell temperature estimation. PV cell temperature estimation models are investigated to assess the performance and reliability of the models specifically for Northern Cyprus weather conditions. Furthermore, environmental factors such as dust affect the performance of PV modules as dust layers cause the attenuation of sunlight which prevent the utilization of incident solar radiation by the PV modules. The accumulation of dust on PV modules is called soiling. The effect of soiling on the performance of PV modules is investigated.Fosil yakıtların yanmasından kaynaklanan sera gazı emisyonu nedeniyle, iklim değişikliği üzerindeki etkiler artmaktadır. Alternatif, sürdürülebilir ve yenilenebilir enerji kaynakları bulma ihtiyacı büyük önem taşımaktadır. Kuzey Kıbrıs'ta güneş enerjisi kaynakları çok miktarda mevcuttur ve gelecek için enerji güvenliğini sağlamak ve iklim değişikliğinin etkilerini azaltmak için kullanılmalıdır. Fotovoltaik (PV) güneş panelleri, güneş enerjisini kullanmak ve elektrik üretmek için kullanılır. PV modüllerinin çalışma hücresi sıcaklığı, PV sistemlerinin genel performansını doğrudan etkiler. Daha düşük çalışma hücresi sıcaklıkları, daha yüksek modül verimliliği ve dolayısıyla daha yüksek enerji üretimi ile sonuçlanır. Bir PV enerji santrali projesinin fizibilitesini ve ekonomik uygulanabilirliğini doğru bir şekilde değerlendirmek için PV hücre sıcaklığının doğru tahmini çok önemlidir. Literatürde çeşitli PV hücre sıcaklık tahmin modelleri sunulmaktadır ve hücre sıcaklığı tahmini için farklı uygulamalarda kullanılmaktadır. PV hücre sıcaklık tahmin modelleri, özellikle Kuzey Kıbrıs hava koşulları için modellerin performansını ve güvenilirliğini değerlendirmek için araştırılmıştır. Ayrıca, toz katmanları güneş ışığının zayıflamasına neden olduğundan, güneş ışınımının PV modülleri tarafından kullanılmasını engellediği için, toz gibi çevresel faktörler PV modüllerinin performansını etkiler. PV modüllerinde toz birikmesine kirlenme denir. Kirlenmenin PV modüllerinin performansı üzerindeki etkisi de tez içerisinde araştırılmıştır.M.S. - Master of Scienc
