According to strain error of the section level and displacement error on the member level, the applicable range of plane-section assumption in the elastic analysis for T-shaped and cross-shaped RC columns was studied. The minimal shear span ratio in the applicable range of plane-section assumption in the elastic analysis of T-shaped and cross-shaped RC columns with different loading cases was presented.Keywords:special-shaped column; plane-section assumption; shear span ratio; crankle ratio作者簡介：陳娟，碩士，工程師，一級注冊結構工程師，Email:chenjuan@ippr.net。參考文獻
