Abstract

Flexural-torsional behaviors of the typical architectural precast beam sections - inverted tee and rectangular - were compared. The inverted-tee beams were designed with a parking live load - 500kgf/$\textrm{m}^2$ and a market-1,200kgf/$\textrm{m}^2$ according to the currently used typical shape in the domestic market building site. The rectangular beams were also designed as the same bottom dimension and area, and reinforced for similar strength as in the cases of inverted tee beams. Two rectangular and two inverted precast pretensioned concrete beams were tested and analyzed
