Typical Analysis Model for Composite CFT Frame

Top

• 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
