摘要：

This paper investigates theoretical ways of dealing with semi-rigid precast beam-column connections to evaluate the strength, rotational stiffness and ductility capacities, with special focus on a specific type of an interior precast concrete beam-column connection under gravity loads. The theoretical study comprised analytical modelling of the moment-rotation response at the elastic limit of steel bars, which has been confronted against experimental results. The proposed model provided good approximations for the secant rotational stiffnesses obtained experimentally. Also, the research includes a validation of a simplified semi-rigid analysis, in addition to an attempt to clarify the ambiguity surrounding the use of the beam-line method.
