تناول البحث تصنيفاً معلوماتياً للتشققات في مقاطع البيتون المسلح استناداً إلى مبادئ المعلوماتية
و بالتحديد علاقة شينون في دراسة هذه التشققات ، و استنتاج مدى احتمال حدوث كل نوع من
التشققات المدروسة في كل مرحلة من مراحل عمل المادة (المرحلة المرنة و ال
مرحلة اللدنة). كما
أنه تم تحديد عوامل الأمان لمقاومات البيتون على الضغط و على الشد حسب نوع التشقق المراد
الحصول عليه و أبعاد المقطع العرضي . و هذا يعطي آفاقاً جديدةً لإدخال علم المعلوماتية ضمن علوم
الهندسة الإنشائية لتصميم مقاطع البيتون المسلح بتشكل التشققات .
This research deals with the minimum cost design of reinforced concrete T-beams
according to the Syrian code. The aim is to minimize the total cost of the beam while
respecting all the design requirements. Traditional method depend on a set of supp
ositions,
in the opposite this methodology aim to reach the optimal solution among a set of
constraints with respect the objective function. So that, using this methodology leading to
the minimum cost reinforced section design.
This research is shown that the problem can be formulated in a nonlinear
mathematical programming format.
Several cases are used to explain the applicability of the formulation in accordance
with the current Syrian code. Traditional method of Syrian code has been used to design
sections in this paper, utilizing the nonlinear programming method provided by Lingo14.0
software from LINDO Systems Inc. The comparison of the results shows that important
saving can be obtained at the total cost of a reinforced concrete T-beams design.
The aim of this work is to demonstrate the role that slabs plays in
RC high-rise buildings. This study shows the mistakes may be
done by modeling slabs as rigid diaphragms. Then after, the
rehabilitation ability of these systems can be more accurate.
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).
