Abstract: An important failure mode of I‐beam gable frames is lateral buckling of the compressed inside flange near the corner of the frame. The magnitude of the buckling load depends on the support provided by the joint at the ...

Abstract: The damping properties of the viscous tuned mass damper are characterized by dynamic amplification analysis as well as identification of the locus of the complex natural frequencies. Optimal ...

Abstract: A family of invariant stress surfaces with a cubic dependence on the deviatoric stress components is expressed as a linear combination of the second and third deviatoric stress invariants. The general format is described ...

Abstract: A random‐vibration‐based force‐response spectrum of a simple oscillating frame is proposed as a simplified measure of the effect of spatial seismic excitations on structures. Such a response spectrum reflects the effect ...

Abstract: New insight into parametric sensitivity in first-order reliability theory is given by studying the parametric sensitivity of the most likely failure point. A formula is derived for the derivative of the unit normal vector ...

Abstract: An analytical model for load-displacement curves of concrete beams is presented. The load-displacement curve is obtained by combining two simple models. The fracture is modeled by a fictitious crack in an elastic layer ...

Abstract: An envelope is introduced by using the Hilbert transform to define a complex conjugate to the excitation and response processes of a linear structure. Time‐limited stationary excitation is treated in detail, and the complex ...
