The aim of this study is to follow and develop a method in order to provide more efficient shape factor performance for Flitch-beams-the first generation of timber-steel-hybrid beams. Basing on the main concept of data tables from the National Association of Home Builders of the United States (NAHB) builders’ beam showing the capacity of Flitch-beams with a variety of sizes, this study chooses one fixed pattern of 2 wood pieces (2×8’’) inserted by a straight steel-plate-core to evaluate and determine the optimized morphology among the variety of cross-sections. It is then applied into the beam as a replacement for straight steel-plate-core. Besides that, to figure out the optimal core, the three types of Rectangular-section, Hollow-section, and I-section based on the same area condition and material should be assessed properly. The first result showed that the comparison relies on numerical data of Maximum bending stress and deflection at mid-span. Following this, the new Flitch-beam was re-calculated, and the experiment was conducted compared to the NAHB builders’ beam pattern. Similarly, the final result indicated that the coordination of the optimized steel core is more advantageous than the patterned beam.
