Seismic Behaviour of Reinforced Concrete Structural Walls Designed According to the European nad Slovenian Standards

Present graduation thesis deals with seismic behaviour of reinforced concrete structural walls of rectangular shape designed according to the European and former Slovenian standards. In the first part of the thesis an eight-storey building is calculated according to European and former Slovenian standards. The construction is loaded by seismic action represented by design ground displacement 0,1g and 0,25g and is situated in eighth and ninth seismic zone according to the former standards. Selected wall is designed for ductility classes medium and high; in addition to being designed as a ductile wall for both classes, it is also designed as a large lightly reinforced wall for DCM. In the design of ductile walls, ductility is either proved by a more precise method or supplied by means of confining reinforcement, specified by Eurocode. In the second part of the thesis various walls designed in the first part are compared. Reasons for differences in reinforcement are given. According to the comparison, the best option both in the areas with strong and weak earthquakes is design for DCM using the sistem of ductile walls. The third part of the thesis deals with seismic behaviour of some of designed walls. Seismic demand is calculated by a non-linear analysis of walls, which is performed both by the N2 method and the non-linear time- history analysis. Results of the analysis shows that wall designed according to the former standards is more vulnerable than DCM wall with confining reinforcement and less vulnerable than DCM wall without confining reinforcement
