| dc.description.abstract | The highly congested building system in many metropolitan cities constitutes a major concern for seismic pounding damage as observed in past earthquakes in different parts of the world. Several buildings located in Ethiopian cities, especially in Addis Ababa, are constructed very closely without adequate seismic separation. This may cause considerable damage or even lead to a structure’s total collapse during earthquake excitation. The aim of this research paper is to identify whether the existing separation distance between adjacent buildings is sufficient or not to avoid pounding. For this purpose, three pairs of adjacent buildings are taken as a case study from different part of Addis Ababa to study their vulnerability against pounding effect. In the analysis, all structures have been modeled by using finite element software programs, SAP2000 and ETABS, with response spectrum function. The analysis has been conducted for elastic structures under seismic zone-2. The results of the analysis shows that in the two cases (case-II and case-III) the separation distances in between are insufficient to withstand the pounding effect, according to EBCS-8, 1995. Due to this, a new RC wall has been provided to increase the stiffness of the building and to reduce the lateral displacement or deformation of the entire structure. This mitigation method shows the significant change in lateral displacement and the period of the buildings. | en_US |
