The research addresses the concept of dynamism and movement in architecture; also the role of time, the human's eye, and perception to classify it “latent or movement”. In addition, analyzing international projects about the thought of dynamism, and employing the vocabulary of the formation. Because of the thought of some architects in the static of the building, which gives the feeling of boredom. In addition, fixed forms are no longer able to meet the needs of users, especially with the increasing of climatic changes and advanced activities. Besides, the misconception that dynamism is only to move the building without looking for the architectural thought behind it, which depend on definite rules and the designer's experience and practice. Therefore, the aim of the research is to guide and employ the concept of dynamism in design, what governs it from the architectural thought to be interactive dynamic buildings by concluding and formulating a methodology to link and reconcile among opportunities of movement, technology “systems – materials”, the required performance, and the factors affecting. Moreover, determining any types of movement more properly and suitable for the nature of the project to root the concept of dynamism, and to give the building an architectural character.
Cairo’s Downtown cinemas were once masterpieces of architecture, screening golden age movies plus witnessing important events. Nowadays, few are still working, while many are ready to be demolished. The best conservation for historic buildings is managing change caused by time. One way to make this happen is smart engaging reuse, thus continue to retain value to current and future generations. Local government and private companies have tried to resuscitate Cairo’s silver screens. This revitalization started with simple face lifting, then developed to rebranding with creative re-use introducing new functions. A key to this creative re-use is across disciplines; new forms of art, music, and media performances. This paper aims to explore four re-use performances bringing the insight of art and media into the field of heritage management. First, “Nassim El Raqs” organized “When dance meets heritage” in Theatre Cinema Eldorado. Second, Radio Theatre re-used to host liveshows; “Al-Bernameg” and “AblaFahita”. Third, Zawya - located in cinema Odeon - launched as the first art-house cinema in Egypt. Last, Teatro Independent Theatre opened their interactive performance “The Metamorphosis” at cinema Elkahira. This paper ends with a framework for rebranding cinemas; comprises both the challenges facing the re-use and proposing community-oriented marketing strategy.
Egypt is facing a huge financial problem reflected on the difficulty of funding public projects either in construction and infrastructure sectors. One of the approaches for such problem is to work cooperatively with private sectors in the form of PublicPrivate Partnership Projects (PPP). This approach, however, is facing a number of challenges. This paper, thus, aims at providing a factor analysis for the establishment of PPP in Egypt through extracting lessons learned in other countries. A literature review has been done to analyze existing factors, followed by a qualitative study of case studies. Finally, a survey questionnaire was conducted on a purposeful sample of 55 stakeholders, either from private or public sectors in order to prioritize and verify factors affecting the success or failure of PPP projects in terms of their severity and impact in Egypt. Results of this paper indicated that bureaucracy, corruption, poor enabling policies and inefficient feasibility studies are among the major barriers that face PPP in Egypt, whereas achieving a reliable contractual structure and political support are the main potentials. Findings of this paper are valuable to stakeholders, decision makers and policy makers in Egypt, as it could guide their thinking towards achieving successful PPP Projects.
In the present study, high resolution remotely sensed data (<60-m resolution) has been used to locate and track changes in urban land cover in Cairo, Egypt. Landsat (TM) images for July months of the years 1985, 1990, 1995, and 2000 have been analyzed to identify the growth of urban region at Cairo. The population growth in Cairo City during the period 1985 to 2000 and its expected rates up to 2035 have been taken into consideration. The results of the study revealed that, a real extent of urban lands of Cairo City could be monitored accurately by using a high resolution Landsat satellite images. Among the main findings is the increase of urban area of Cairo from 267.38 Km2 to 548.13 Km2 through the period from 1985 to 2000 with percentage annual ratio estimates 7%. A significant correlation between the rate of increase of Cairo urbanized area, ΔUA, and the rate of population growth, ΔPA, has been found in the simple form, ΔUA = 40.85 – 100.6 ΔPA. Therefore, if the rates of population growth and human activities in Cairo City continued, the urban area will reach to be 1193.85 km2 by the year 2035. In addition to serious local climate changes will prevail.
Siwa Oasis has a unique vernacular architecture, built with walls of an earth martial called (Kerchief), and roofs of palm tree trunks. The uniqueness of Siwa’s cultural heritage is accentuated by its natural heritage. However, modernization reached this exotic place. Concrete and multi-story buildings started to appear changing the original vernacular atmosphere, and local residents started to adopt new building technologies to suit a modern lifestyle, threatening the integrity of the cultural heritage. Vernacular Kerchief buildings are known to be cooler than conventional modern concrete; specially in hot daytime, but Kerchief walls are extremely vulnerable to water (scarce rain destroys the buildings and sanitary water used inside threatens the safety of the bearing walls). But, locals often prefer the modern (hot) buildings to the traditional cool yet vulnerable buildings. This paper aims at analyzing the thermal behavior of vernacular Kerchief buildings, compared to modern buildings, to define what exactly makes them perform better thermally (the material, the mass or the design). Simulation of ten parameters and combinations of a model building in Siwa was conducted, using EnergyPlus and Design Builder software to determine the parameters that affect thermal comfort.
Our earth is a living body that has energy veins flowing all over, just like the human body where blood flows from and to the heart. These natural earth energies are as old as the earth existence and interact with everything on its surface. They were believed to have either a healing effect in “Power Spots” or a stressful effect in “Geopathic Stress Zones” that can change the normal functioning of human beings and damage their health. Thousands of years ago, these energies’ effects were considered during designing the built environment. This no longer takes place although recent research discovered that the urban ambiance is badly affected by electromagnetic radiation from different sources. Moreover, one of the main objectives of urban design is bringing to the user a sense of wellbeing and emotional satisfaction. The paper argues that respecting the natural earth energies during the design process will affect the wellbeing of the users. Consequently, the paper undergoes an exploratory process through a survey in Al-Sultan Hassan mosque using observations and a structured questionnaire to investigate this relationship. The survey confirmed that following the earth energy grids in the design affects the visitors positively and enhances their abilities and wellbeing.
Local scour around bridge piers and abutments, induced by hydraulic deficiencies, is the major cause of bridge failure. Most of the available empirical formulae have been developed based on experimental laboratory tests using uniform sand. However, the bed sediment in the field is to some extent graded. To develop a more reliable formula, well graded sand was used in the experimental flume of this study. In the present paper, the local scour depth around exposed single pile founded in sandy soil was studied experimentally in the laboratory to predict its maximum value. New scour depth prediction equations were developed and compared with some of the previous published equations, other researcher's data, and field data and they were found in very good agreement with them. For complete definition of the scour hole geometry, new equations were developed to estimate the scour hole width at different locations around the pile, thus helping in introducing protection measures for the scour hole. The developed equations are applicable for both clear-water and live-bed scour cases.
This paper is a pioneering step to furnish the theoretical basis behind the semiempirical punching formula. Principles of the Boundary Element Method BEM and the theory of elasticity are adopted to establish the rationale behind the punching shear stress equation proposed in building codes. It was found that an envelope could be constructed between the theoretical shear stresses in the two directions embracing safe punching values computed from ACI empirical formula. The present research further substantiates this effort through developing a BEM-based checking methodology for punching limit state for columns of any irregular cross-section shape – a task that traditional punching equations fall short of satisfying. This methodology is first verified via regular shape columns then adopted to demonstrate its capability to consider columns with irregular cross sections. Finally, some real-world examples are conducted to demonstrate the accuracy, efficiency, practicality and reliability of the proposed computational “theoretically-based” methodology in checking punching of reinforced concrete columns with arbitrary (either regular or irregular) cross-sections.
Two criteria of good vehicle suspension performance are typically their ability to provide good road-holding ability and increased passenger comfort. The main disturbance affecting these two criteria is terrain irregularities. Active suspension control systems reduce these undesirable effects by isolating car body motion from vibrations at the wheels. The paper describes an adaptive fuzzy control (AFC) schemes for the automobile active suspension system (ASS). The design objective is to provide smooth vertical motion so as to achieve the road-holding (with as small as possible tire deflection) and riding comfort over a wide range of road profiles. Effectiveness of the proposed control scheme is demonstrated via simulations. With respect to the optimal linear control (LQR), it is shown that superior results have been achieved by the AFC.
