Abstract
Nowadays most regions all over the world are exposed to earthquake hazard. So, it is very essential to take the lateral loads effect into consideration in the design of the multi-story and high-rise buildings. Lateral loads obtained by wind and earthquakes cause high stresses, develop sway movement and cause a great damage to the structure. It is very significant for the structure to have an adequate strength to resist vertical loads simultaneously with adequate stiffness against lateral forces. Therefore, Shear walls are one of the most common structural elements used for stabilization of the building structures against lateral forces. Providing the shear walls in buildings can increase the lateral stability to resist the seismic lateral load. Short historical remarks and types of earthquake resistant building and its virtues are studied. A literature review of the previous studies is provided on the seismic behavior of reinforced concrete building influenced by shear walls as one of the lateral resistant systems. All detailed information about the design considerations of earthquake loads recommended by the Egyptian Code for Loads (ECL/2012) is provided. Also the different methods of analysis are presented. A study of models of twenty / thirty multi-storied building to study the effect of variation of the shear walls arrangement and its dimensions in the plan configuration. The models have been analyzed under the effect of static loads using a finite element program ETABs v.16.2. Also, dynamic analysis (Response Spectrum) of such models has been carried out. The results of such analysis have been used to investigate the seismic parameters (the story displacement, the story drift, base shear, and story shear). These results have been led us to the best configuration of shear walls arrangements for the structure. The results from response spectrum analysis were studied. Comparison of the methods of analysis was done. Also, another study has been investigated to study the effect of vertical irregularities such as soft story, mass irregularity, and openings in shear walls. Moreover, a study of Tube, Tube-in-Tube, outrigger and braced frame systems is studied and compared them with shear wall system in form of (the story displacement, the story drift, and axial force demands on the beams and columns, and bending moment).
