1. SEISMIC FRAGILITY AND COST ANALYSES OF ACTIVELY CONTROLLED STRUCTURES
Published: 4/15/2013
Authors: Kevin K F Wong, John L Harris
Abstract: 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. ...

2. Seismic Damage and Fragility Analysis of Structures With Tuned Mass Dampers Based on Plastic Energy
Published: 4/2/2012
Authors: Kevin K F Wong, John L Harris
Abstract: The effectiveness of using a tuned mass damper (TMD) to improve a structure‰s ability to dissipate earthquake input energy is investigated through the use of seismic fragility curves. Nonlinear material behavior of the structure is captured using th ...

3. Nonlinear Modal Analysis of Structures with Rigid-End Offsets
Published: 3/31/2012
Author: Kevin K F Wong
Abstract: 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 nonli ...

4. SEISMIC ENERGY ANALYSIS OF STRUCTURES WITH NONLINEAR FLUID VISCOUS DAMPERS ‹ ALGORITHM AND NUMERICAL VERIFICATION
Published: 6/1/2011
Author: Kevin K F Wong
Abstract: To protect structures from suffering significant damage during a major earthquake, fluid viscous dampers (FVDs) have been used in both newly constructed and seismically retrofitted structures to effectively reduce dynamic responses. The main benef ...

5. Nonlinear Dynamic Analysis of Structures Using Modal Superposition
Published: 4/13/2011
Author: Kevin K F Wong
Abstract: A fast nonlinear dynamic analysis algorithm based on modal superposition of structural response incorporating both material and geometric nonlinearities is proposed. Because linear modal superposition has found great acceptances in performance-base ...

6. SEISMIC APPLICATIONS OF NONLINEAR RESPONSE SPECTRA BASED ON THE THEORY OF MODAL ANALYSIS
Published: 1/28/2011
Author: Kevin K F Wong
Abstract: A fast nonlinear response spectra analysis algorithm based on the theory of modal analysis and superposition is proposed to overcome the drawbacks of using the time-consuming nonlinear response history analysis in seismic design. Because linear moda ...

7. NONLINEAR MODAL ANALYSIS AND SUPERPOSITION
Published: 7/25/2010
Authors: Kevin K F Wong, John L Harris
Abstract: 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 anal ...
