Abstract: A study is made on the parametric torsional stability of an elastic cantilever of rectangular cross section under dynamic axial loading. The coupling between the longitudinal and torsional motions ...

Abstract: The inelastic seismic response of a class of one‐way torsionally unbalanced structures is presented. The structural model consists of a single mass supported by bilinear hysteretic elements. The yield strength of the model ...

Abstract: A study has been made on the parametric excitation of a nonlinear system with hardening springs. In the parametric excitation of linear systems, the only subharmonic predicted is a subharmonic ...

Abstract: The steady-state responses of a simple pendulum with a hinge exhibiting bilinear hysteretic moment-rotation characteristics and parametrically excited by a sinusoidal oscillation at the base is ...

Abstract: A simple method to obtain the load distribution on the resisting elements of symmetric and eccentric setback structures subjected to lateral loading is presented. The compatible load concept is employed by the proposed ...

Abstract: A study is made on the parametric stability of open thin-walled beams under axial load. A set of nonlinear equations of stability and the appropriate boundary conditions are obtained using the ...
