The seismic force-resisting system (SFRS) of a building consists of a three-dimensional collection of elements that transmit loads and forces from the point of occurrence to the foundation and supporting soils. This system typically consists of horizontal
The primary seismic force-resisting elements in buildings are horizontal diaphragms, vertical framing elements, and foundations. Together, these elements, comprise the seismic force-resisting system (SFRS). In reinforced masonry structures, the vertical

In 2007, the National Institute of Standards and Technology (NIST) awarded a National Earthquake Hazards Reduction Program (NEHRP) "Earthquake Structural and Engineering Research" contract (SB1341-07-CQ-0019) to the NEHRP Consultants Joint Venture, a
Seismic fragility represents the probability that the structural response exceeds a given performance limit state due to a specified intensity of ground motion, and it has a direct relationship with the cost of rehabilitating the structural system. In this

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
