Seismic Retrofit of Existing Steel Moment Resisting Frames with Innovative Materials: Large Scale Hybrid Simulation Tests
Abstract eng: This paper discusses the experimental validation of a new system for seismic retrofit of existing steel moment resisting structures. The system consists of infill panels made of a High Performance Fiber Reinforced Concrete (HPFRC) that is able to strain harden in tension. A two-phase experimental program was designed and conducted at the Network for Earthquake Engineering Simulation (NEES) facility at the University of California, Berkeley. This program utilized large-scale hybrid simulations of a 2/3-scale, 2-story steel moment frame designed in 1980s retrofitted with HPRFC infill panels. The numerical challenges during the experimental program including the development of a phenomenological model that is able to simulate cyclic deterioration of the HPFRC infill panels are summarized and validated with the available experimental data.
