SEISMIC: Concrete Confinement Model Synthesis Study

项目名称：	SEISMIC: Concrete Confinement Model Synthesis Study
摘要：	A review of the literature reveals (a) seismic design practice has progressively advanced since the 1971 San Fernando earthquake, and (b) the seismic design practice adopted today has gone through rigorous experimental testing to ensure satisfactory response of bridges when subjected to moderate to large earthquakes. Concrete used in today's practice typically has higher strength than that used in the development of commonly used confinement equations. With an increase in concrete strength, the section ductility capacity will increase, but the ultimate strain capacity will be reduced. Hence, the confinement requirement and its influence on member and system ductility should be examined as a function of concrete strength. the amount of confinement can vary significantly using existing equations as demonstrated by Sritharan et al. (2008) for a 14-inch prestressed concrete pile.
