Strain distribution in the section along with the height of composite beams and the cross-deflection changing with load were investigated, the performance of the interface of concrete and steel beam, transverse steel and lift of concrete plate performance were analyzed. Furthermore, contractive analysis of the relative slip between new corrugated and flat perforated plate connector was studied in the same condition. The results show that the connector has better flexural properties, and section strain is in line with the assumption of plane section. The corrugated perforated plate connector has high shear ability, connection performance, and the relative slip in interface of concrete and steel beam is little. The research can provide theoretical foundation for the application study of the corrugated perforated plate connector in large composite structure.Keywords: composite beam;corrugated perforated plate;new connector; mechanical performance; experimental study*住建部科學技術項目資助(2009-K2-25)，蘇州市市級建設科研項目資助（2010-88-04)。作者簡介：陳建兵，副教授，Email:szctt2009@163.com。參考文獻［1］LEONHART F, ANDRA W, ANDRA H P, et al.
