استخدمت في تشييد أبنية المطارات العديد من الأنظمة الإنشائية، كما تختلف تلك الأنظمة باختالف وتطور نماذج الطائرات وازدياد عدد الركاب، وسيتضمن هذا البحث استعراض لمباني بعض المطارات والتي تم تشييدها وفق نظام الإنشاء المعدني الذي حقق مجازات أكبر وفراغات معمارية مختلفة لمبنى الركاب من حيث الشكل وتأدية الوظيفة المطلوبة. يتضمن هذا البحث دراسة تطور التقنية المعدنية المستخدمة في إنشاء المطارات وبشكل خاص لمبنى الركاب وبيان مدى تأثيرها في تحقيق الفراغ المعماري بأبعاده ومجازاته وتلبيته لمتطلبات الوظيفية المطلوب تحقيقيا داخله لا سيما تأمين الراحة والأمان للركاب وسهولة توجيه حركتهم إلى أماكن اقالع الطائرات، كذلك تأمين التهوية والإنارة الطبيعية للمبنى.
Many constructionl systems were used in the construction of airports. These systems vary according to the development of the various aircraft models as well as to the increasing number of passengers. This study will include a review of some airports buildings, which had been built depending on the metal construction technique that achieved larger architectural dimensions and spaces for passenger terminal in terms of shape and function. This research includes a study of the evolution of the metal technique used in airport construction especially for passenger terminal showing its effect in realizing the architectural space including its dimensions and spaces and in meeting the functional requirements inside it particularly securing passengers safety, comfort, and the ease of controlling their movement to the taking off places, as well as securing ventilation and natural lighting of the building.

Abstract
Nowadays, man is the medium of great issues, thus it's necessary to
study private relationships that could be found in the environment
created by architects and how they fit man and his needs to create
more suitable architectural spaces.
Architectural researches rarely
spoke about void directly; their theories focused on the physical
elements and structural motives of buildings regardless of the
preexistence of void in architecture. An architect should design in such
a way to create the void surrounding him in the first place, not the
physical formulas that would hold formal meaning.
Few information were dedicated to study architectural voids and their
specifications in particular, wherein it is so wide and comprehensive
field, especially when we take its gradual consequent scales in
consideration. City voids are formed to fit city scale (level), residential
voids are formed to fit neighborhood scale and private voids are
formed to fit home scale.
Thus, it's necessary to clear the importance of void and analyze it in
order to conceive it fully as a fundamental base in architectural design
process.
This research presents a study with the help of Finite Element Method and the use of
CATIA V5 program to know the behavior of a permissible link - column used in metal
structures at high temperatures (on fire). In this article we will present an an
alysis using the
finite element method using the CATIA V5 program for the effect of different engineering
parameters (plate thickness, screw diameter, reinforcement nerves) on the behavior of
joints used in metal structures on fire. We also studied the effect of the number of bolts on
the stresses and transitions in the link and their comparison with the welding cases. We
studied and analyzed the studied model and obtained the deformation and failure schemes
at high temperatures, the flow charts and the temperatures that show the behavior of this
link to the fire. We also obtained the stress and strain schemes for the link and the transport
and load schemes at different temperatures and the behavior of this link at these different
temperature.
In this search, has been studied set of practical experiences for compacting several
metal powders composed a metallic alloy based iron from powders with a proposed
geometric shapes (cylindrical). Several tests were done in order to reach the relat
ionship
between the final apparent density for the compact with a sintering time, and study
changing the geometric dimensions of the final compact after the completion of sintering
process during different time periods.
The tests and Measurement results had been demonstrated that sintering time affect
positively on the apparent density of the final compact which Manufactured by technique
metal powders, and thus will increase its strength, where proportionality is directly
proportional access even to a certain extent. And also its effect was an obvious shrinking
diameters samples used in the tests. And changing (increase or decrease) in height samples.
Search has shown the great importance of the follow-up studying and analyzing the
relationships which associate that variables of metal powders technique each other, and
their different effect on the final compact.
The paper proceeds to review the concept of Residential Urban Spaces and their classification, and to limit the variables affecting the performance of the spaces and identify the ways to measure these variables. Then, it conducts a field survey of a
variety of spaces in the City of Lattakia. The paper also proceeds to conduct a questionnaire to the urban spaces users and the residents of the surrounding segments of the population in order to identify the users’ opinions and reviews on the current status of the space performance and identify the most important needs and activities favored by the users within the space. It also identifies the reasons behind selecting certain spaces rather than others.
After that, the paper proceeds to analyze the data in order to develop a mathematical model that determines the most important variables that affect the performance of the space, positively or negatively. Consequently, a mechanism will be set up to boost the performance of the Residential Urban Spaces by influencing the most powerful variables affecting the spaces and rejecting the weaker ones. Finally, making recommendations to activate the spaces and make it a safe interactive human, socio- cultural environment.
In this research, It has been studied the effect of compaction pressure on
the final roughness for the top and down surfaces for the green compacts
that manufactured by meal powder technique and it has been studied also
the effect of piston veloci
ty (compaction velocity) on the final roughness
for the same two surfaces.
The results present that the curved for the top surface roughness is
completely decreasing and as the pressure has increased, the value for
roughness has reduced and the mean roughness (Ra) has very close
values, where these values have made curve from second degree and
opposite relationship. The results were same for the down surfaces but
with different variations.
