Taiwan High Speed Rail Project, R.O.C.

A HSR link of 354km/220mi, with 242km/150mi on elevated structures, between Taipei and Kaoshiung was opened in 2007. In 2002/03 Mr. Komar was supporting VCE in the detail design. He was mainly responsible for the IDC, the Seismic and Rolling Stock Analysis for various more complex bridges, the Valley Bridge with a series of single spans (35m/114ft and 45m/148ft) with a total length of 940m/3,084ft, two 3-span prestressed bridges (140m/459ft and 105m/344ft), a 7-span composite steel plate girder bridge with concrete deck (260m/853ft), and a 3-span steel truss bridge (191m/627ft).
In 2007 the Taiwan High Speed Rail Corporation (THSRC) has contracted Dr. Frieder Seible with StD&A and David Evans and Associates, Inc. (DEA) to investigate and offer expert opinions on a dispute between the THSRC and contractors related to methods for design of girder torsion and girder force transfer. Mr. Komar performed in-depth literature review regarding torsional stiffness for box girder bridges. A detailed analytical study was performed, and results of this work formed the basis for the comments, opinions, and conclusions.
