This study aims to evaluate the ultimate shear strength of the connections of composite steel beam(CSB) composed of reinforced concrete (RC) column and steel beam. Total number of specimens of CSB were 66 carried out by researchers in domestic and foreign countries. The specimens were considered with various types of shear reinforcement such as shear reinforcement of vertical and end concentration, band plate and stud bolt and welding of main bar, etc. Ultimate shear strength of the connections with various reinforcement types was evaluated through experiments and code equations. In this study, experimental result were compared with code formula(KBC-RC, JIS-RC, JIS-SRC) and Zsutty`s Equation. The average test-to-code ratio of ultimate shear strength for all specimens was 1.05(KBC-RC), 1.59(JIS-RC), 1.16(JIS-SRC), and 0.96(Zsutty). Categorized by shear reinforcement type of specimen, ultimate shear strength by code formula and Zsutty’s equation deviated from 6% to 41% from experimental results and the average of deviated percentage was 25%(KBC-RC), 29%(JIS-RC), 29%(JIS-SRC), and 21%(Zsutty). Specimen reinforced at end with fixed plate showed the best correlation with code formula and Zsutty’s equation.
