Abstract
This paper deals with the analysis and design of two buildings for two different uses.
The first one is intended for residential use, while the second is designed for office
usage. These buildings will be located in the city of Trondheim, Norway.
The main objective of this document was to determine how the different structural
designs for the same building affect in the final costs of the structure, taking into
account different materials. The materials considered during the design and analysis
phases for each of the buildings have been: reinforced concrete, structural steel and
precast concrete. The structural scheme adopted foreach building have been a constant
in the various alternatives considered in order to analyze how choosing one or the other
material influences the final cost of the structure.
Various structural solutions were posed and compared to choose the one considered
most suitable in each case depending on the specific needs.
The design and structural analysis was performed using the software ETABS 2015. In
all cases the design was done based on the rules specified in the Eurocodes, which has
been the reference standard. The main actions considered were the gravitational loads
and lateral actions, such as wind and seismic actions. Additionally, structural
verifications such as maximum vertical displacement and maximum storey drift were
done to ensure the validity of the designs.
After obtaining the designs for each alternative proposed in both buildings an economic
analysis was conducted, which produced a final budget for each of the designed
structures. In order to do this, the 2010 edition of the “Norwegian price book” (Norsk
Prisbok 2010) was used as a reference price database.
Finally the different alternatives have been compared in order to determine the
advantages and disadvantages of each and their influence on the final cost.
It was observed that, for both buildings, the precast concrete alternative was the most
competitive one in terms of economy with respect to the other alternatives.
Description
This thesis aims to analyze the impact of different structural designs on the building construcion cost. The result of that analysis determines the best constructive alternatives and also those which allow better utilization of space, ensuring the best use of economic resources.
