Earthquake resistant design of a multistorey RC building

Abstract

By far, the highest natural hazards faced in the zones that have high seismicity are earthquakes. Albania is part of the Adriatic-Ionic and is considered as a moderate seismic region. During recent years Albania has faced a high number of small earthquakes, medium-sized Earthquakes (with a Magnitude M 5.4-5.9) and a smallest amount of large earthquake (considered earthquakes with a Magnitude M>6.5). Due to these earthquakes a lot of aspects of the communities where the earthquake happens are affected. Starting with life injuries, loss and damages on structures. Structures affected by earthquakes in recent years usually are left as they are, no structural repairs are made. The main focus and purpose of this study is to analyze and design a multistorey building based on the seismic response of the building using the response spectrum and time history analysis. The finite element method (ETABS) is used to evaluate the behavior of structure, modelling and designing the multistorey building based on the ETABS analysis. In this study, a 10-storey building, with 2 story’s underground is taken into consideration. Based on the response spectrum analysis and time history analysis a comparison of results has been made and then the detailing and designing of the concrete frame elements. For designing and detailing the concrete frame elements CSI Detailing software is used. Results have been interpreted and an example of detailed design of concrete frame elements such as: slab, beam, wall and column are presented in this study. To design the concrete frame elements the seismic method is used since one of this study objectives is doing the Earthquake Resistant design of a multistorey builing.
