Analysis studies were carried out on asymmetric column to beam connections of steel plate rolled forming steel-PC composite modules. The main variables of analysis are asymmetric column composite or non-composite, thickness of steel plate and reinforcement or not. As a result of the analysis, the strength of the local buckling decreased from the upper flange of the beam. The connections are improved so that the upper flange surface of the beam has both the moment and horizontal shear resistance elements. As a result of the analysis of reinforced connection, the strength and stiffness increased linearly regardless of the column composition and the thickness of the stiffener. The stability of the connection and the possibility of securing the momentum were confirmed. This result is reflected in the experimental plan of the connection.
