On the basis of the experimental study on shear properties of L-shaped section columns,  the shear strength formulas, in which the moment ratio and shear-span ratio were considered, and a suggested desigrung fomula for shear strength of L-shaped section columns are given. Coruparing the computational results using the suggested designing formula with the testing formula, satisfactory agreement is obtained.
Keywords: frame column; shear property; L-shaped section; moment' ratio; shear-span ratio
