There have been numerous studies dealing with the environmental and social aspects of the
type of buildings with internal courtyards, through studying the functions of the internal
courtyard, environmental, utilitarian, social and formative. but th
ese studies did not address
the importance of internal courtyard in achieving the ease of spatial orientation, through its
role in easy access to the space required In buildings in general, and in university buildings
in particular.
The research starts from the following hypothesis: The morphological and Syntactical
characteristics of the internal courtyard of the university buildings affect the ease of
orientation of the users, and aims to identify these characteristics that achieve easy access
to the goal. For this purpose, including theoretical and practical colleges, where a special
description of the morphological characteristics of the internal courtyard in the university
buildings, and determinants that help the designer in the use of the internal courtyard in
designing of spatial configurations of the university buildings to achieve the ease of spatial
orientation.
The behavior of the basaltic shear diaphragms of the remaining buildings of ancient times
was investigated as experimental research,and its resistance to natural factors and
horizontal loads resulting from wind and earthquakes,to take advantage of
them in the
maintenance of modern buildings,which are associated with floors and beams as horizontal
shear diaphragmsIn the hot and cold areas of the African continent, Asia and other similar
areas,to replace the reinforced concrete shear diaphragms,and metal shear diaphragms that
lose their resistance to the above factors. When the buildings are inspected, the vertical and
slanted slits resulting from the side loads are placed,it was found that the appearance of the
cracks related to the hardness of the shear diaphragm section, the basalt stone
specifications and the design of the shear diaphragm base.The research was conducted
to determine the durability, water permeability and resistance to pressure and tensile
strength of basalt stone samples used in historic stone buildings and their location in
laboratory methods.Horizontal loads resulting from seismic intensity were determined on
the front of the building at the tile level according to international requirements and
specifications.The method of calculating the basaltic shear diaphragms was
applied by applying arithmetic to build a basalt stone from several floors and a basement,
taking into account the characteristic resistance of basalt, depending on its density from
pressure and stretching and basalt stone in calculating.
The main purpose of the research was to partially replace the
reused substrates with natural preservatives. Five mixtures were
formed with different percentages of the recycled granules (0-
100%) and for constant W/C, and the study of the possibility of
disposal of the ruins of the destroyed buildings through their reuse
in the work of the concrete and the positive effect on the
environment.
In this research, the danger and the horizontal force effects on the
engineering structures will be explained, and we will focus on the
horizontal winds force effects on the bridges, the high buildings and
special engineering structures. The resul
ted loads will be analysed and
evaluated in both static and dynamic methods. In the end of the
research, two practical examples will be shown for the two methods.
The walls containing phase change materials (PCM) play a significant role in the
air conditioning of buildings. However, one of the characteristics which limits the use
of PCMs is their low conductivity. It is possible to solve this problem by coup
ling a
metal matrix with the PCM. The aim of this study is to determine the optimal size of a
wall which allows a complete change of state, and a homogenization of the temperature
without a too fast change-of-state rate. To study the thermal behavior of the wall, we
have carried out a numerical simulation using the COMSOL® software in considering a
unit cell. To describe the change of state, the method of the equivalent heat capacity
has been used. Paraffin has been chosen as PCM (melting temperature 24.5 °C). The
influence of the nature and the volume fraction of the metal were determined. The case
of honeycombs made of aluminum has been specifically treated.
this paper reviews definition of tall buildings, a brief
history of their development which can be broadly classified into
three periods, and the primary factors of their evolution. In
addition to studying their lateral load resisting systems with
some
examples of each one, we presented seven major structural
systems each one suit different architectural forms and allows
specific height.
Using Finite Element Analysis (FEA), a comparison between
PushOver Analysis (POA) and Response Spectrum Analysis (RSA)
is done in this research to explore the application limits of POA on
the irregular frame buildings from reinforced concrete.the
comparison contains (failure mechanism, displacement, and
ductility).
This article, will look at the structural development of the high
rise buildings and the factors that led to these developments, and so out
of the basic structural systems, even new classifications for
constructional systems (internal systems external systems), as well as
most construction systems deployed use.
The Phase Change Materials (PCM) are materials which absorb a great quantity of
energy during the change of phase solid /liquid and relies it during solidification
An application of these materials is thermal energy storage. The PCM integrated into
materials of the building can reinforce their inertia and reduce the power necessary for the
heating and air conditioning. This is particularly true for the buildings of the tertiary sector
whose envelope is light. Nevertheless, one of the characteristics which limits the use of the
PCM is their low conductivity.
The objective of this article is to propose a selection of materials having a
conductivity high enough to make it possible to ensure an air conditioning in summer
while limiting, even while removing, the use of energy (electricity or fuel) thanks to walls
containing these PCMs. This article consists of two parts:
- The first part exposes the problems of the study and specifies the context in which
the use of a PCM as a passive air conditioning system fits.
- The second part fixes the selection criteria which will allow, in a first approach to
choose certain materials.
In this paper, we present a new algorithm to automate the detection
and extraction of buildings from satellite images, this algorithm is
distinguished since it overcomes some obstacles that limit detecting
within other methods, such as the differe
nce in shape, color, and
height of buildings, and it doesn't need multi-spectral images or other
complex and high cost images.
