SEISMIC FRAGILITY AND COST ANALYSES OF ACTIVELY CONTROLLED STRUCTURES

April 15, 2013
Author(s)
Kevin K. Wong, John L. Harris
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

A Direct Analysis Method for Drift-Sensitive Steel Moment Frames

February 17, 2011
Author(s)
John L. Harris
Design interaction equations for steel members in a moment frame are formulated based on inelastic member capacities that account for geometric imperfections, residual stresses, second-order effects, and, in some cases, eccentric loading. The analytical

NONLINEAR MODAL ANALYSIS AND SUPERPOSITION

July 25, 2010
Author(s)
Kevin K. Wong, John L. Harris
Linear modal analysis and superposition technique has been used extensively in earthquake engineering and seismic applications for decades, and it is here extended to the nonlinear domain by representing the material nonlinearity using the force analogy
