This final year project presents the structural analysis and design of a reinforced concrete residential building, with ground floor dimensions 13,0 x 38,0 m, consisting of ground floor and three storeys. The basic loadbearing system may be described as a cross-wall system where the load-bearing walls of thickness 25 cm are provided at 6,3 m distances perpendicular to the longitudinal axis of the building. Each wall consists of eight precast panels 6,6 m long and 3,0 m high with indented shear joint. The floor system is based on omnia-plates (thin prefabricated plates with in-situ concrete topping). The behaviour of wall panels under seismic actions was considered. Two different cross walls were analysed – one solid wall and one wall with openings (considered as coupled wall). The dissipation of seismic energy is achieved in coupling beams above the openings and through shear sliding across the vertical joints. The principle of weak vertical and strong horizontal connection has been applied. Reinforcement drawings are provided for the analyzed wall panels.
