Predictions of Instability Using the Modified , J -Resistance Curve Approach

Source

This paper presents a method for predicting the behavior of an untested structure using the modified J, J_M-resistance curve approach. The method combines the J_M-R curve, calibration functions, and the expression for J_M for the untested geometry to provide the load-load point displacement characteristics and the J_M-T_M diagram of the structure. These two records contain all the information needed to assess structural behavior, maximum load, the tendency for instability, and the load-point displacement at every point.
