Abstract

Title: Innovative Applications of Damage Tolerant Fiber-Reinforced Cementitious Materials for New Earthquake-Resistant Structural Systems and Retrofit of Existing Structures (NEES-2005-0047)

Year Of Curation: 2011

Description: NEES testing facilities and associated simulation capabilities will be employed to develop new coupled wall systems and retrofit schemes for framed construction through the use of high-performance fiber reinforced concrete (HPFRC). This research was conceived from the idea that the next generation of reinforced concrete (RC) structures should utilize ductile cementitious materials in critical regions, rather than extensive reinforcement detailing to provide shear resistance and concrete confinement. A high-performance fiber reinforced concrete (HPFRC) that is ductile in tension, does not spall in compression, behaves like a confined concrete, and is capable of providing confinement to normal reinforcement, will be used. In addition to enhancing confinement and flexural behavior in plastic hinging regions, HPFRC materials are capable of providing ductility and energy dissipation capabilities to shear critical members that are normally a difficult design issue for RC structures. The use of HPFRC materials for such members will lead to less complicated reinforcement details, will be easier to construct, and will provide a high degree of damage tolerance, leading to superior seismic performance and reduced post-earthquake repair costs. The research will be conducted by a diverse and multidisciplinary team from three major universities, Michigan, Stanford and Illinois, with expertise in structural engineering, computational simulation, materials engineering, information technology and cyberinfrastructure deployment. Cooperative assistance with computation and simulation requirements has been offered by the MGRID and Sakai research groups at the University of Michigan.
