Abstract
The project is a structural analysis and 3D-Dynamic design of an office building in Ramallah city, known as AL-Huriya, which consists of a seven stories, with 3.5 height except the first floor with 4m story height.
The building will be first designed under a static load, after that it will be designed for dynamic by exposing the building to lateral load, finally a prestress concrete will be used to design the building to compare it with the reinforcement concrete, to conclude many factors that should be taken into consideration in designing any structure. These include economic factors , durability and the safety of its inhabitants.
The major characteristics of this project is to cover various structural elements such as slabs, beams, columns and footings. Hand calculations and SAP2000 V.12 are both used in the analysis and design process.
The prospective outcome from the comparison between reinforced concrete versus prestress concrete, found to be that the reinforced is more economic under project conditions , with a higher thickness for slabs and beams. On the other hand less amount of material needed in prestress one.
