| dc.description.abstract | In the past many cities around the world have been struck by a range of earthquakes which have resulted in the loss of many lives along with the destruction of properties. Cites have been turned into dust and rubbles. Earthquake causes different intensities of shaking at different locations and the damage induced in buildings at these locations is also different. In many countries, tools have been designed and incorporated in their national building codes to decrease the hazards caused by earthquakes starting from the inception of design to the final stage of construction to harmonize designs for the reduction of seismic risk. The goal of this study is to focus on the solution mechanisms to be addressed in strengthening of older and existing reinforced concrete framed building to ensure an appropriate level of safety for occupants in the event of an earthquake. As it is known, the earthquake design parameters have been revised in the new Ethiopian Building Code Standard. According to EBCS 8: 1995, Addis Ababa was categorized in zone 2 in the seismic hazard map. But the new revised code locates the city in zone 3, which doubles the peak ground acceleration. More over the city is expanding towards the outskirts of Addis Ababa like Akaki, Bole Arabssa. In this study, it is considered that the building stock designed earlier before the revision of the code will not survive an earthquake based on the new peak ground acceleration. This brings a question on how these buildings will be strengthened before this kind of destruction and loss of life and property occurs in the city. Therefore, the outcome of this study will benefit the owners as well as the authorities on the retrofitting procedures as well as solution mechanisms of reinforced concrete framed building structures are undertaken. | en_US |
