The retaining walls are one of most types of engineering constructions and it have built from natural stones before discovering concrete, Where natural stones have considered one of the early human materials used in building engineering constructions for thousands of years, and many facilities in ancient civilization still existing effects so far, And after the discovery of the concrete and reinforced concrete, the retaining walls which was built from natural stones diminished relatively Despite the years this retaining walls has not lost its luster and brilliance, and there is increased interest in recent years in using new building material which consists of manufactured stones where used together with traditional construction materials in several areas both in geotechnical engineering or building … Etc . This retaining walls present simple technical solutions and it is desirable for aesthetic reasons and simple implementation and resistance to external conditions, In addition to being economical solutions limited cost compared to traditional reinforced concrete retaining walls. This research deals with the study of the behavior of Segmental Stone Retaining Walls (SRW) under the static and dynamic loads and parametric study of the most important factors which influence stability of these retaining walls.

Research summary
تتناول هذه الدراسة سلوك واستقرار الجدران الاستنادية الحجرية المصنعة (SRW) تحت تأثير الأحمال الستاتيكية والزلزالية. تعتبر الجدران الاستنادية من أقدم أنواع المنشآت الهندسية التي استخدم فيها الإنسان الأحجار الطبيعية قبل اكتشاف البيتون. ومع تطور مواد البناء، ظهرت الأحجار المصنعة كبديل اقتصادي وجمالي للأحجار الطبيعية. يهدف البحث إلى دراسة استقرار وسلوك هذه الجدران باستخدام الطرق التحليلية، مع التركيز على تأثير زاوية ميل الجدار وزاوية ميل التربة خلف الجدار، وكذلك تأثير مقاومة القص بين الأحجار. تم استخدام طريقة القوازن الحدي ونظرية كولومب لحساب معامل الدفع الجانبي وقوة ضغط التربة الجانبي الفعال في الحالة الستاتيكية، وطريقة مونونوبي أوكابي في الحالة الزلزالية. أظهرت النتائج أن الاستقرار الداخلي هو العامل الحاسم في استقرار الجدران، وأن زاوية ميل الجدار عن الشاقول تلعب دوراً هاماً في زيادة الاستقرار. كما أن وجود مفاتيح القص بين الأحجار يزيد من استقرار الجدران بشكل كبير. توصي الدراسة بإجراء المزيد من الأبحاث باستخدام موديلات تجريبية وطرق تحليل أخرى مثل التحليل العددي والستاتيكي والديناميكي.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة في مجال الهندسة الجيوتكنيكية، حيث تقدم حلولاً اقتصادية وجمالية لمشاكل استقرار الجدران الاستنادية. ومع ذلك، يمكن توجيه بعض النقد البناء للدراسة. أولاً، الاعتماد الكبير على الطرق التحليلية قد يقلل من دقة النتائج في بعض الحالات، لذا كان من الأفضل تضمين تجارب ميدانية أو نماذج تجريبية لدعم النتائج. ثانياً، الدراسة تركز بشكل كبير على الأحمال الستاتيكية والزلزالية، ولكنها لم تتناول بشكل كاف تأثير العوامل البيئية الأخرى مثل التآكل أو التغيرات المناخية. أخيراً، يمكن أن تكون الدراسة أكثر شمولية إذا تم تضمين تحليل اقتصادي مفصل لتكلفة الجدران الاستنادية الحجرية مقارنة بالبدائل الأخرى.

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.
Frame structures contribute to resist the seismic loads. On the other hand, frames work efficiently to increase the ductility of buildings. Therefore, many techniques were used to improve the resistance against lateral loads where steel shear walls are considered to be one of these ways. This research aims to study the effect of inserting steel shear wall on the resistance of the reinforced concrete frame against earthquake loads. In this study, Finite Element Method (FEM) using Geometrically and Materially Non-Linear Analysis (GMNLA) was performed. Pushover analysis is used to explore the behavior of the steel plate in-filled reinforced concrete frame against lateral loads. Moreover, the effect of plate thickness was undertaken. On the other hand, an opening is made in this plate. Then, the influence of the position and dimension of this opening on the resistance was observed. This study shows that using a steel plate shear wall with or without opening can enhance the resistance to seismic loads significantly together with the deflection decrease.
Braced frames and steel plate shear walls (SPSWs) have both been shown to be useful in the seismic retrofit of buildings. While both these systems have merit, no guidance exists to determine which of the two approaches is preferable in terms of pr oviding maximum displacement ductility and energy dissipation per cycle for a given strength. This paper describes and compares results from numerical evaluation using FEM, in which the nonlinearity of materials and the nonlinear effects of the large displacement was included for tow frames. The results of numerical study was identical to the experimental tests, then a barometric study was achieved by changing the thickness of infill plate then the area of the cross sections of braces, after that the width of the frame was modified. The result shown that using steel infill plate is preferable when the dimension of bay is three times the height, while using braces is more adequate for frames in which the dimension of bay is less than three times the height.
RC moment-resisting frames (RCMRFs) have commonly been used for low-to-moderate rise buildings in seismic prone regions. RCMRFs can perform well when they are subjected to strong earthquake ground motions if they are properly designed and detailed to dissipate the seismic input energy through deformations in inelastic range. The connections between beams and columns thus become critical components to the performance of these structures. In conventional RCMRF connections, the width of the beam does not exceed the width of the column. Adopting a flat beam system for the design scheme provides many advantages, such as the reducing the amount of formwork required, the simplicity for repetition, and the decrease of the required story height. RCMRFs with flat beams have been used extensively, despite the lack of sufficient information on how this system behaves under earthquake loading which leads the codes to restrict the use of flat beamcolumn connections in earthquake prone regions.
The surface hardening by shot peening (S-P) is one of the processes used to increase the hardness of aluminum alloys surface. This step tends to increase of the fatigue strength for this alloy because of the creation of compressive residual surface stress layer, which resists the initiation and propagation of cracks. But in some cases, the opposite of this effect occurs, the fatigue strength decreases because of the initiation of surface micro cracks. The influence of this process on the fatigue strength of two aluminum alloys 1050A and 2219 was investigated. (S- N) curves are determined for two surface conditions produced by shot peening and uppeening. As well as the alloys were studied under loading programme low-high & high-low. This paper deduced that the fatigue life of aluminum alloy 1050A was reduced by a percentage of (23%) because shot peening caused high surface roughness, and consequently high local stress, but the fatigue life of aluminum alloy 2219 was increased by about (38%) because the shot peening caused the creation of compressive residual stresses.
