Composite Construction: The composite construction is one of the modern structures. Therefore, Papers deal with the design, research and development studies, experimental investigations, theoretical analysis, and fabrication techniques relevant to the application of composites components, ranging from individual components such as plates and shells to complete composite structures.
Rehabilitation of Structures: Structural repairs and rehabilitation is a process of reconstruction and renewal of structural elements. A research involves determining the origin of distress, removing damaged materials and causes of distress, as well as selecting and applying appropriate repair materials that extend a structure’s life.
Design and Analysis of Bridges: Concepts and Analysis provide a unique approach, combining the fundamentals of concept design and structural analysis of bridges in a single volume Researchers dealt with principal design and analysis concepts in a unified approach, including modeling and detail design aspects, which are discussed for different bridge typologies and structural materials.
Structural Construction Materials: In general, all materials used in constructions can be studied and investigated to develop or enhance each materials' usage in structural engineering. Therefore, one research direction is looking at these materials to improve the structure containing these materials.
Non-linear dynamic analysis of reinforced concrete structures: The dynamic analysis includes the effect of earthquakes on reinforced concrete structures and assessing the damages that induced in the buildings, considering the earthquake damage. While for bridges, the dynamic analysis should consider the influence of both earthquakes and vehicle movement.
Non-linear structural analysis of the interaction between reinforced concrete structures and soil: This approach includes studying the effect of the interaction between the reinforced concrete structure and soil, taking into consideration the constitutive relationships that describe the non-linear behavior of both the soil and the structural elements of the building.
Ferrocement concrete: Ferrocement concrete consists of two different materials, cement mortar and layers of wire mesh, which can be used in the rehabilitation of damaged buildings. In addition, the possibility of molding it to produce various geometric shapes used in simple facilities such as car park shades and lightweight shell roofs.
Stability of Underground structures under Static and Dynamic Loading: The analysis and design of the underground structures like tunnels, powerhouse cavern, underground metro railways, oil and gas storage, mining, and many other uses is very important issue in the stability of such structures. Many factors should be considered in the stability analysis such as the interaction between the underground and surface structures under static and dynamic loading, sequence of excavation, and type of support system.
Problematic Gypseous Soils: Gypseous soil is a problematic soil that suffers from collapsing and lose its strength under saturation and leaching process. Many additives as stabilizers added to gypseous soils to reduce the effect of water. These additives comprise of lime, cement, asphalt compound, reinforcement, and mixed additives.
Sustainable Development of Using Waste Materials in Geotechnical Works: Many waste materials have detrimental effects on the environment; hence, attempts have been carried out to evaluate the use of waste materials in geotechnical works as additives to improve the properties of the soils. These waste materials produced from a construction-demolition process or as industrial waste process. The studies emphasize that such materials can be re-used or recycles in the engineering geotechnical.
Ground improvement and soil stabilization: This line of research is concerned with ground treatment methods to enhance the physical and mechanical properties of problematic soil (expansive soils, collapsible soils, soils containing soluble materials, and random fill soils) to make it suitable for the civil engineering uses. This research includes physical and chemical processes, soil injection and grouting, soil reinforcement with various materials, and the application of other methods to ensure suitable bearing capacity for the facilities built on them and to determine the susceptibility to volumetric change, particularly settlement and swelling.
Partially saturated soil mechanics and applications: This subject is considered as one of the relatively recent topics for studying the mechanics of soils where theoretical and practical bases have been laid down based on a three-dimensional soil analysis, taking into consideration the effect of suction forces in addition to vertical stresses. It is a field that is a reconfiguration of all the axes and topics of classical saturated soil mechanics and has very wide applications. Our department is a leader at the level of the Middle East by adopting this line of research science 2003 until now.
Physical and numerical modeling applications to study soil behavior: The department involved a study and development of research related to the topics of geotechnical engineering applications; through designing physical models aimed at studying and analyzing some applications of soil mechanics as slope stability, retaining walls, bearing capacity and settlement and the effects of some factors on them. This follows; relating the obtained practical results with numerical models through advanced software’s applying a parametric study. These design charts are proposed for engineering use purposes. Finally, these results were checked through a real case study.
Geoenvironmental engineering: It is a field based on the use of engineering applications of soil mechanics to study the reflection of soil mechanics, treatments and applications on the surrounding environment and to ensure its protection. It is a scientific field that includes applications in rock and soil mechanics, environmental engineering, and groundwater hydrology and their impact on human health and the environment. Geoenvironmental engineering deals as well with issues related to a complex problem, such as soil contamination and diffusion and transport of pollutants from a landfills, remediation of polluted sites, and reuse of materials.
Modification of Paving Materials: Recently, this domain is considered as one of the essential topics that deal with the behavior, advantages and disadvantages of the modification of asphalt binders and mixtures with polymers (plastomeric and elastomeric types), warm-asphalt additives (Zeolite, Sasobit, Petroleum wax), starch, citric acid, ABS…etc. under short and long-term ageing conditions. As well as, to the mechanistic-empirical (M-E) design approach of these mixtures.
