概要

Since end-plate type connections possess high initial and linear plastic connection stiffnesses due to strain hardening effect, a three-parameter power model may not be applicable for estimating M-θ_r curves of the connections. Here, it is tried to apply a four-parameter power model which is composed of initial and plastic connection stiffnesses, initial connection moment, and shape parameter. These parameters for a total of one hundred and sixty-eight experimental connection data installed in the connection database, are determined and are listed. And also analyzing two semi-rigid frame examples with the proposed model, an applicability of the model is numerically discussed. From this study, it is seen that the four-parameter power model can be used for numerical analysis of semi-rigid frames instead of directly using of connection database.
