Teacher, 1990; Teaching Excellence Award, 1989 Professor Hsu authored numerous research papers on shear and torsion of reinforced concrete and published two books: “Unified Theory of Reinforced Concrete (1993) and “Torsion of Reinforced Concrete (1984) In this (his third) book “Unified Theory of Concrete Structures (2010), he integrated the action of four major forces (axial load, bending, shear,...
