Today, in the current Vietnamese design standards for semi-precast reinforced concrete and steel frame structural systems, the connections of main elements such as beams and columns are commonly considered as either perfectly hinged or rigidly fixed. This assumption is adopted because of the simplicity in design and analysis process but it is not consistent with actual behaviour in practice of structural systems. The connections between columns and beams have partial restraint depending on the type of used connection. The analysis of structural system with consideration of the effect of this restraint would result more exactly and economically. However, it is also more time required because of complexity of analysis process with consideration of flexibility of connections in the case of lack of suitable calculation method. The paper presents the analysis of plane frame systems with different of models of semi-rigid connections using finite element method. The analysis process was implemented by MathCad programming software and the results of this study will obtained by conducting of numerical examples. From there the conclusions and recommendation of calculation and design for steel and semi-precast frame systems will be proposed.
