Abstract

The objective of this thesis was to design a concrete portal frame with two column spacings of 12 meters and 6 meters and its structural elements in a building located in Hämeenlinna city, Finland. A comprehension study on the concrete design chapter of Eurocode 2 was done before proceeding on the calculation process, the materials’ properties. The corresponding ca-pacity diagrams from concrete product manufacturers in Finland can be assistance tools during the calculation process. The aim of this thesis was to analyse the differences of the structural ele-ments of the concrete portal frame between two column spacings of 12 and 6 meters. First, the design calculation procedures of the structural el-ements were studied in accordance with “How to Design Concrete Struc-ture using Eurocode 2”, which was published by the Concrete Centre, then the designed results were compared with capacity curves of the selected elements which can be found in the websites of Finnish concrete manufac-turers. Finally, conclusions of the comparison were drawn. The results turned out to be as expected. Less reinforcement requirement in the col-umns, less height and width requirement of the roof elements were ex-pected. A useful derivative study of these elements was expectedly gener-ated.
