Abstract: In this paper the ultimate strength of a 16 storey reinforced concrete frame-wall building is being investigated using nonlinear pushover analysis. This building is designed according to British Standard 858110, which does not have any special provisions for seismic load. A general purpose finite element software ABAOUS is used to model the 16 storey frame-wall building. A microscopic model is used where the wall is modeled by 3-D brick elements and the beams and columns by 1-D beam elements. The ultimate base shear is computed for two loading cases, the ultimate loading case and the common loading case. The results of the pushover analysis for the above loading conditions are presented. The base shear capacity is also compared with the base shear demand due to far field effects of earthquakes. The nonlinear pushover analysis of the 16-storey reinforced concrete frame-wall building· indicated ultimate base shear of 14.63% and 15.39% of the building gravity load for ultimate and common load cases respectively, when the concrete cube strength is 30 MPa. For concrete strength of 20 MPa, the corresponding values are 12.35% and 12. 7% of the building gravity load. The building possesses considerable strength to withstand tremors caused by earthquakes.
