Abstract:The behavior of laterally loaded flat-plate structures is strongly influenced by the nonlinear deformations at the plate-to-column connections. In this paper, a simple procedure is described for predicting the nonlinear moment-rotation behavior of flat-plate-to-column connections. That behavior is expressed by standardized moment-rotation functions. These functions were derived using a modified Rambert-Osgood function and all available experimental data. The influence of the most significant connection parameters such as the steel ratio, concrete strength, gravity loading, etc., on the connection behavior is incorporated into the functions. A physical model of the column region is described which facilitates the incorporation of the functions into a structural analysis computer program. The accuracy of the functions has been demonstrated for several plate-column connections. The computer analysis program is also described and an example is considered to compare results obtained from the program with those published in the literature.
