Abstract
This projects presents a commercial center being constructed in Bidia, it's now in the construction phase. It consists of 5 floors including a ground floor to be used as a garage and they would be explained through this project. The project is being constructed over an area of 912m2 .
This projects aim scompleted as to design for seismic forces, footings.
to present. The projects is made with some constrictions and challenges; For example there are some large spaces between columns and the outer sides of the Mall are made of glass so the deflection values should be made to minimum to prevent the fracture of the glass. Indeed, there's a cantilever inside the project which need to be considered. In addition to the stairs and elevator.
The project outline will be as follows: first, introduction about the project including details about the architectural design, materials properties and the loads that the building is subjected to. Second, preliminary design according to ACI 318-14 code. Third, a 3D model will be constructed using Sap. Finally, gravity design will be done for many selected structural elements. The methodology of making checks at results comparing Sap ad handmade values. This project is important because it deals with a real, large and existing facility, which is expected to receive a lot of people every day.
The methodology undertaken started by choosing a local site for the redesign process where the geological profile and the value of the bearing capacity were known. The used codes for both obtaining loading values and the design procedure are ASCE 7-10 and ACI 318-14. The geological profile helped determining the seismicity factors according to the seismic maps for the area chosen. This led to determining the type of the structural system resisting both gravitational and lateral loading cases according to the permitted types in the ASCE 7-10. Afterwards, the characteristics of the construction materials as the crushing strength for concrete and so on were determined for all structural elements. Approximating applied loads for all structural elements followed next in order to suggest preliminary section sizes for the structural elements. Once a preliminary representation of the structure was present, the modeling procedure commenced using the ETABS software. Final section sizes were determined ensuring no failure happened while maintaining serviceability as well. The design procedure followed according to the code specified beforehand. ETABS results were checked by designing a sample of each structural element manually. Beams of B5 and LVL30, all slabs, all vertical members were detailed. Foundation system of mat foundation and piles was modeled and designed using SAFE software. Stairs and a sample of non-structural wall were also designed and detailed.
