Seismic reduction factor of reinforced concrete framed structures

Seismic reduction factor of reinforced concrete framed structures The seismic reduction factor depends on a number of parameters and thus cannot be reduced to a simple constant value, such as given by the majority of seismic design codes. Indeed, this research work aims to study the main parameters influencing this factor through reinforced concrete moment framed structures (RCMF). The studied structures are first designed according to the Algerian seismic code RPA99/2003. Furthermore, the seismic reduction factor and its three components, namely, over-strength, redundancy, and ductility, are evaluated in detail as function of number of stories, plane redundancy, and the seismic intensity using pushover analysis based on an inverted triangular load pattern. In addition, the confinement effect is considered to describe the non-linear behaviour of confined concrete, fibre model for the non-linear modelling of columns, and Takeda model to simulate the stiffness degradation. The obtained R values were generally greater than the proposed ones in design codes for low-rise RCMF, comparable for the medium-rise and considerably lower for high-rise RCMF structures. For low- and medium-rise structures, the security under seismic shaking is insured when designed according to RPA99/2003; whereas high-rice RCMF structures may be subjected to a serious lack of security under seismic loading. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Asian Journal of Civil Engineering Springer Journals

Abstract

The seismic reduction factor depends on a number of parameters and thus cannot be reduced to a simple constant value, such as given by the majority of seismic design codes. Indeed, this research work aims to study the main parameters influencing this factor through reinforced concrete moment framed structures (RCMF). The studied structures are first designed according to the Algerian seismic code RPA99/2003. Furthermore, the seismic reduction factor and its three components, namely, over-strength, redundancy, and ductility, are evaluated in detail as function of number of stories, plane redundancy, and the seismic intensity using pushover analysis based on an inverted triangular load pattern. In addition, the confinement effect is considered to describe the non-linear behaviour of confined concrete, fibre model for the non-linear modelling of columns, and Takeda model to simulate the stiffness degradation. The obtained R values were generally greater than the proposed ones in design codes for low-rise RCMF, comparable for the medium-rise and considerably lower for high-rise RCMF structures. For low- and medium-rise structures, the security under seismic shaking is insured when designed according to RPA99/2003; whereas high-rice RCMF structures may be subjected to a serious lack of security under seismic loading.
