My research experience and areas of interest involve earthquake-resistant steel structures, applied probability, and mathematical modeling of structural systems.
I have extensive experience in the development of new moment-resistant steel connections for buildings located in areas of high seismicity. I was the PI on a grant to perform full-scale tests on the Slotted-WebTM connection, and I performed the nonlinear finite element analysis of the prototype SidePlateT Connection. I also derived the closed form solution of the stiffness matrix of the Reduced Beam Section. This research is present in the March 2003 Journal of Structural Engineering and AISC's Engineering Journal, 2nd qtr, 2008. The Slotted-WebTM, SidePlateTM, and Reduced Beam Section moment-resistant connections now exist in many steel structures in high-seismic areas. I have also worked on the seismic demands of simple steel connections, and developed design criteria that must be met in order to transfer lateral earthquake loads in perimeter frame systems. This work is summarized in an ASCE Journal of Structural Engineering paper (June 2004).
I recently completed an AISC research project, Brace Frame Gusset Plate Research - Phase I Literature Review, which resulted in a 345 page report.
I have developed new methods to efficiently compute the probability of failure of complex structural systems, calibrate instruments, and design steel connections.
My research projects have included many finite element analyses (FEAs) of steel components. I am an author of several conference papers related to the finite element modeling of bolted connections. |
