Abstract: The conjugate structure method is developed from first principles for the general three‐dimensional case including shearing deformations and various sources of excitation. It is shown that the analogy is a direct result ...

Abstract: The results of an experimental investigation of the inelastic behavior of short wide‐flange steel beams commonly used in eccentrically braced frames is presented. The test specimens were subjected to a severe cyclic loading ...

Abstract: The eccentrically braced steel frame provides an efficient structural system for resisting lateral loads caused by wind or seismic activity. In some applications, this versatile system can reduce overall material requirements ...

Abstract: Issues of dynamic stability for a single-degree-of-freedom system subjected to a time-varying axial load are presented. The linearized differential equation of motion for the model structure is given by the well-known ...
