Abstract :
Today, the use of steel shear walls has been considered as a side load system in steel and concrete buildings. The use of a shear wall in comparison with steel fixing frames has led to a 50% saving in steel consumption in buildings. Due to the simplicity and the possibility of making the shear wall in the factory and installing it locally, the speed of the system is high and the cost of the operation is reduced to a high degree. This system is harder to slip out of the hardest harnesses that X has, and with the possibility of opening anywhere, it has the effectiveness of all braking systems in this regard. The energy absorption and non-reciprocating behavior of this system is better than braking systems. Various regulations, such as the Canadian Steel Structures Regulations and the FEMA 450, provide standards for the design of steel shear walls. In 2005, the rules for designing special steel shear walls were added to the AISC Seismic Design of Steel Structures. For designing a steel shear wall and determining the amount of force tolerated by it, three methods of strip modeling, membrane modeling and nonlinear analysis are presented. So far, no method has been proposed for the design of an open-cut shear wall that does not rely on finite element software, and the only manual method for designing a shear wall that can be used for the shear-free shear wall can be used. In this thesis, the behavior of reinforced concrete shear reinforced with CFRP composite rebar under seismic loads is evaluated. To do this, first, using the ABAQUS modeling software, a three dimensional model of the shear wall and the desired structure is developed and then the model is processed and analyzed using finite element method. In order to analyze and evaluate the behavior of reinforced concrete shear reinforced concrete with CFRP composite rebar, all dynamic oscillatory loads applied to the structure and its real boundary conditions are defined and then a regular grid of elements for meshing and structural analysis based on finite element method is created. will be. In this thesis, first, a concrete shear wall of steel with steel reins under loading due to New Zealand Earthquake standard earthquake mapping is investigated. In the following case, the same shear wall is replaced with CFRP composite rebar and again based on the same The seismic load will be analyzed to consider the effects of composite reinforcing replacement. Then, after simulating the output contours such as stresses, strains, displacements applied to the structure, it is evaluated and analyzed.
