Abstract
In high seismic development countries, buildings are more vulnerable to seismic hazards than developed countries. This is mainly due to the absence of seismic design guidelines which correspond to the kind of structural systems and practices which are often used in such areas of the world. Response reduction factor (R factor) are important tools for seismic design usually used to define the degree of inelasticity required during a seismic event in lateral structural systems. With a non-linear static analysis, the output of structure can be evaluated. This includes estimating the criteria for structural strength and deformation and evaluating the capacity available at the required performance level.
The thesis contains a study to evaluate the seismic response modification factor of multi-storey reinforced concrete structures with different slab systems. A review of studies and research published in scientific journals and conferences related to the topic of the thesis and a detailed presentation of the finite element method. Types of material models (concrete and steel) used in making the nonlinear analysis model. Samples of materials used and the mathematical equations have been reviewing to make a model and the program used in the Sap2000 Structural Analysis. An analysis was made of multi-storey multi bays reinforced concrete frame and flat slab subjected to pushover analysis (POA) until collapse and compared with the published practical results. The ability of the program to predict the shape of the collapse and the displacement value of the structural elements was verified. An applied study was conducted to evaluate the seismic response modification coefficient for concrete installations with different slab systems. Concrete structures with three, six and nine floors have been designing and contained multiple bays according to the Egyptian Code for the Design of Concrete Structures. A non-linear analysis of these structures was made under the influence of increased seismic forces and the seismic response modification coefficient was calculated compared with those contained in the Egyptian load code, IBC 2012 code, and the American code ASCE7-10. The results have been compared and discussed through many tables and graphs. Moreover, recommendations have been written for future research in this field.
