This report about the National Earthquake Hazards Reduction Program (NEHRP) during fiscal year 2011 is submitted to Congress by the Interagency Coordinating Committee of NEHRP, as required by the Earthquake Hazards Reduction Program Reauthorization Act of
The effectiveness of using a tuned mass damper (TMD) to improve a structures ability to dissipate earthquake input energy is investigated through the use of seismic fragility curves. Nonlinear material behavior of the structure is captured using the Force
The nonlinear modal analysis (NMA) methodology for analyzing moment-resisting framed structures is here extended to include frame elements with rigid-end offsets. Four keys components of the NMA methodology for conducting dynamic analysis of nonlinear
