Abstract
This project presents the structural analysis and design process for the Indonesian Rehabilitation Hospital located in the city of Nazareth, Palestine. It consists of four floors above the ground floor and two underground floors (basements). The floors vary in use, including parking and storage rooms. Each basement floor has an area of 1853.65 m². The external walls and some of the inner walls are composed of reinforced concrete, while partition walls are made of blocks. This project contains a sequence of steps in analysis and design taking into consideration many loads that will be applied on the structure such as gravity load (superimposed, live and snow loads), lateral loads (soil pressure, surcharge load and seismic loads), for seismic load response spectrum was used for analyzing the performance of the structure in earthquakes and equivalent static was used to comparer his result with response spectrum results and take the largest among them; to be more conservative. The structural system was chosen to be building frame systems (special reinforced concrete shear walls)for basement floors and in Y- direction all floors above ground floor, and dual system with special moment frame capable of resisting at least 25% of prescribed seismic forces in X- direction all floors above ground floor, soil type was classified as type C. The methodology in this graduation project is to fully understand the architectural plans, to locate or to redistribute - if it is needed - the columns. Moreover, to know and assign the correct static loads according to the architectural plans and floors usages. Furthermore, to suggest different structural systems for the slabs from which to choose the best and the more convenient one, two-way solid slab with beams system was chosen. In addition, to have a preliminary dimension of the elements of the structure. After that, to apply all the data to the programs mainly on ETABS and to validate the outputs of the model through various checks such as compatibility, equilibrium, stress-strain and long- term deflection, taking into consideration the deference percentage not to exceed 10%, structural checks were also done such as horizontal and vertical irregularities, P-Delta and drift check. The objective of these checks is to make sure the serviceability, stability and strength of the structure. The references in this project were several codes which are American Concrete Institute ACI 318-19, American Society of Civil Engineers ASCE 7-22 and American Society for Testing and Materials ASTM. This structure was represented on the Extended Three-dimensional Analysis and design of Building Systems ETABS 20 software
