Abstract | Reinforced concrete buildings make up the majority of Australian building stocks. Structural elements of these buildings are often designed with limited to nonductile detailing. With a very low building replacement rate many of the Australian buildings are vulnerable to major earthquakes and pose significant risk to lives, properties and economic activities. "Cost-effective mitigation strategies for building-related earthquake risk” under the Bushfire and Natural Hazards Cooperative Research Centre (BNHCRC) aims to develop knowledge to facilitate evidencebased informed decision making in relation to the need for seismic retrofitting, revision of codified design requirement, and insurance policy. Seismic vulnerability assessment is an essential component in the project. This report presents sets of fragility curves that have been developed for two types of reinforced concrete buildings, buildings that are mainly supported by shear or core walls and buildings that are supported by walls and moment resisting frames. The seismic assessment frameworks, the approach for selection of ground motions and the development of archetype building models will be discussed. The fragility curves for low-rise, mid-rise and high-rise buildings for both types of limited ductile reinforced concrete buildings will be presented in the forms of PGV, MMI and RSDmax as intensity measures. |
