Phase II of Performance-Based Design


  • Research on Phase II is ongoing
  • Initial work involves developing new constitutive models for "fiber" beam finite element model for RCFT tubes
  • "Fiber" element model will be implimented in OpenSEES
  • An objective of Phase II is to assess seismic demand in composite RCFT braced and unbraced frames
  • A second objective is to develop a reliability-based performance-based design procedure by comparing seismic capacity and demand for RCFT frames for performance objectives ranging from Immediate Occupancy to Collapse Prevention
