v2.02.302 SDLL302 — Beam subjected to the « El Centro » accelerogram at each end, one out of phase with respect to the other

Summary:

The objective of this test is to validate multi-support in linear transient dynamics on the simple case of a beam subjected to acceleration on each of its ends where it is embedded. Two finite element models of Timoshenko beams are proposed, in linear transient dynamics resolved on a modal basis and on a finite element (direct) basis:

• modeling A: the same accelerogram is applied on both ends; single-support and multi-support solutions are compared;

• B modeling: the accelerogram is out of phase between the two ends.

B modeling is also involved in the validation of option MOMENT_EQUIVALENT of POST_RCCM /B3600.
