Résumé :
|
The global compressive capacity of steel members subject to lateral rigid body dynamic excitation is examined numerically with a dynamic nonlinear finite-element analytical algorithm that uses the implicit Newmark-β integration procedure combined with the Newton-Raphson iterative scheme. The algorithm was validated with experimental results. Parametric studies on 180 box, tube, and W shapes are presented. The members included initial geometric imperfections along their lengths. On the basis of the parametric study, a simplified formula for the buckling capacity of a steel member under lateral rigid body excitations is presented that may be considered for the use in the development of a design formula.
