Abstract

The present diploma thesis deals with the design of a tall steel building, with the purpose of construction and the usage as an office space. The analysis and design of the building were done in accordance with the current provisions of European Standards using the structural analysis and design software SAP2000. First, reference is made to the history of tall buildings and their rapid constructional evolution to date with examples. In addition, the floor systems used in the design of tall buildings are presented and the two categories of loading systems are analyzed. Also, the typical structural systems of tall steel buildings used in constructions are presented and analyzed with examples. Then, an extensive reference is made to the determination of the actions on the constructions, while at the same time excerpts of the regulations are presented, on the basis of which the appropriate values of the loads of the building occurred. Also, the combinations of actions in ultimate limit states and serviceability limit states according to Eurocode 1 are described. The seismic actions that act on the building were taken according to the modal response spectrum analysis, as defined by Eurocode 8. Then, the simulation steps of structure in the software are presented and the analysis and design of the structural system of the shear frames with vertical braces (CBF) is performed. Then, the results of the analysis and design of the tall building, as they emerged from the software are presented and some checks are performed for the X – braces. Finally, the diagram of the same weight of the total construction and the elements in the form of columns are presented.
