Réduction de la vulnérabilité du vieux bâti par l’Analyse du comportement structurel face aux sollicitations sismiques à l’aide de l’outil informatique
(Epau, 2017) MAHMOUDI,Ahmed; SI YOUCEF,Youcef [Rapporteur]
Seismic risk assessment of historical structures of old buildings has become an increasingly important subject, because of the high vulnerability of this heritage to the seismic risk.
Our research aims to establish a numerical simulation on the mosque of old Tenes, in order to highlight the critical zones in this monument.
This mosque was collapsed during the main shock of the 1954, Chlef earthquake on which the mosque underwent huge modifications, for this the structural analysis, was carried out at the base a modeling of the two models in order to study the behavior of the mosque before and after the earthquake.
Response spectrum analyzes were performed to evaluate the seismic response of both structures;
The numerical analyses is based on finite element modeling(FEM) using the Robot Structural analysis 2017 program, after which the results obtained have been interpreted to detect the different vulnerable zone un each model.
Les Escaliers urbains Algérois, un patrimoin à reconnaitre Cas d'étude: quartier nord de Larbi Ben M'HidI
(Epau, 2018) ABKARI ,Imen.; KASSAB,Nasserine [Rapporteur]
The urban stair is one of the main elements of the urban tissue, it act as a driving force of
daily life of the inhabitants, on the one hand they are nodes, elements that articulate the urban
fabric, and voids which are landmarks in the city, on the other hand , they are the place of
social cohesion or weave the different relationships between users :trade, relaxation, leisure,
meeting ... etc.., however , over time and with different successive changes which affected
the economic, social and political all cities including the Algerian city of Algiers , most of
urban stairs have lost their vocation, the urban stair continues to play a major role in the city.
The problematic of urban stairs today refers to recurring issues in several fields such as
urban planning, architecture and sociology course.
The main objective of this study is to identify the problem of negligence and dysfunction of
these elements, and to verify some parameters of urban stairs on the use of these areas,
through:
- Identification of morphological characteristics of the studied urban stairs, by focusing on
their physical configuration, and reveal the dialectical relationship between urban forms and
their various users.
- Identification of the different modes of use and ownership of these urban stairs, and to
identify factors that influence these patterns of users.
- The determination of the various parameters that are involved in the creation of a daily life
in the urban stair, through the verification of formal, functional and climatic parameters.
As urban and touristic potentialities, the challenge is to see how these stairs that don’t
participate in the life of the city, can be revitalized and reintegrated into animated, urban or
touristic circuits, also, to see if their patrimonialization can protect them from any
appropriation.
Le ‘BIM’ au service du patrimoine La Halle Volta comme cas d’étude
(Epau, 2018) KHELIFI,Mohamed Zakaria; HORRA,Badr El-Mounir [Rapporteur]
We live today in a world constantly evolving, new technologies allow us to enhance and facilitate human activities and bring us closer to optimal efficiency. Building information modeling (BIM) is one of this technologies, BIM allow building professionals to collaborate, simulate and exchange information’s thanks to a digital model that are easily accessible. The tools used for simulations offered by this process allowed us to jump from simple 2D and 3D representations to other dimensions such as project times schedule and cost, introducing new concepts such as 4D and 5D models.
Meanwhile, facing this constant changes that are born from this evolution we must take care of our heritage and make it a priority. It is clear that we cannot aspire for a future without learning from our past. Thus this thesis has as a subject a special building dating to the end of the XIXth century, “La Halle Volta”. An emblem of Algiers’s industrial architecture features many qualities in the architectural, historical, and urban aspects. Unfortunately, we observe only few actions that aims to take in charge this heritage which suffers from a luck of acknowledge that in turn generate more degradation and risks for the durability of this building.
Our work aims to apply the BIM process in the fields of constructed heritage management throughout Algeria in order to improve the efficiency of interventions and in the same time safeguard and showcase our legacy. This translates to the use of this process to a largely acknowledged methodology in Algeria, the architectural monography will be applied to our case study in order to extract the points where BIM provides opportunities for the monography, the points where it displays weaknesses, and finally to assess new future development options. This points in conjunction with our engagement to showcasing this building, constitute the essence of our thesis problematic and the starting point for our hypothesis and objectives.
La Façade de l'édifice algérois du XIX ème-XXème Cohérence et système oppositionnel
(Epau, 2017) HAMOUDI,Hocine; BELOUCHRANI- AMROUCHE ,Wahiba [Rapporteur].
The work presented in this thesis is part of the study and comparative analysis of a
set of facades of buildings from the colonial era. In view of their heritage values and importance in
national history, we have proposed to carry out an analytical study to identify their characteristics.
The context for this study is the downtown area of Algiers. Our analysis approach consists in
making a sharp reading of the elements composing the facade. At the end of this analytical work,
we succeeded in identifying the morphological structures of these facades and determining the
modalities of their compositions. Our work could serve as a basis for rehabilitation operations when
it comes to a fac¸ade of the XIXth and XXth century or to the reinterpretation of this architecture in a
more contemporary style.
Essai de catégorisation du système décoratif en faïence dans l’architecture palatine de l’époque ottomane à Alger .
(Epau, 2018) TOUATI,Yasmine; ZEKAGH,Rachida
The houses and palaces of the Ottoman era of Algiers are considered to be the jewels of the architectural production of that time. These buildings have a rich decoration that expresses itself through a variety of materials used: earthenware or enamelled ceramics, carved marble, wood carpentry and carved stucco and openwork.
Our research focuses on faience decoration in the palaces architecture of Algiers during the Ottoman era. It sets itself the objective of categorizing this type of setting in order to detect the logic and principles of composition.
The methodological aspect is based on a monographic approach combining documentary research and field investigation. This work is organized around three parts:
• The decor in the palaces architecture of the Ottoman era
- Palaces architecture of Algiers (intramural) at the time Ottoman
- The decor in the palatine architecture of Algiers at the time Ottoman
- The faience decoration in the palaces architecture of Algiers during the Ottoman era
• Case study: faience decor
- Presentation of the case studies
- Appreciation of faience decor - case studies
• Categorization of faience decoration in the palaces of Algiers
- Try to categorize the faience decoration
- Interpretation of the categorization grid
In conclusion, the practical issues of our research would be:
• Participate in the knowledge of Ottoman architecture through the identification of faience decoration in the palaces
•Contribute to the restoration of endangered homes and residences in the Algiers Medina, through the establishment of a manual of restoration of the decor very useful to the PPSMVSS of the Kasbah of Algiers palaces of Algiers.
