From 2019 until now, Al-Sayed Mall, which consists of twelve floors, is being implemented in the city of Qalqilya, and this mall has been chosen to be re-analyzed and re designed it in this graduation project with sixteen floors. The floors vary in usage, some floors are hotels, storage, garages, some are offices, and some are restaurants. The external walls were divided into shear walls with stone in some areas and into glass in others, and the internal walls were divided into blocks in some areas and glass in others. This project was analyzed and designed for gravity forces such as dead loads, superimposed dead loads, and live loads, and it was also analyzed and designed for seismic forces. The Response Spectrum method was used in the seismic analysis, and the Equivalent static method was used to check the results of the Response Spectrum (value of base shear). The soil under the structure was determined to be type C. Also, building frame system-ordinary reinforced concrete shear walls was used in this project, meaning that seismic forces are loaded onto the shear walls only, and vertical loads are on the frames. The appropriate dimensions for each structural and non-structural elements were found in this project, such as slabs, beams, columns, and walls of both types, and the structural plans which include layout and detailed reinforcement for each structural element were prepared. The reference in this project was several codes which are American Concrete Institute ACI 318-11, American Society of Civil Engineers ASCE 7-10 and American Society for Testing and Materials ASTM. This structure was represented on the Extended Three Dimensional Analysis and design of Building Systems -ETABS 16- software and the 14 structure was then analyzed and designed on this software. Several checks have been performed on the results of the ETABS software in the analysis. Several checks have been performed on the structural elements to check the serviceability, strength and stability of the structure. Such as: checking the deflections with the two types of immediate and the long term deflection. The equilibrium check was done and the percentage of error was very small in the results, not exceeding 5%. After that, several checks have been performed on seismic forces analysis results to ensure the ability of the structure to withstand these seismic forces, such as the p-delta effect, drift check, vertical and horizontal irregularities, the base shear check, and the distribution of base shear on the floors.
