Résumé

{Context. Constraints on the Galactic bulge and bar structures and on their formation history from stellar kinematics and metallicities mainly come from relatively high-latitude fields (vertical bar b vertical bar > 4 degrees) where a complex mix of stellar population is seen. Aims. We aim here to constrain the formation history of the Galactic bar by studying the radial velocity and metallicity distributions of stars in situ (vertical bar b vertical bar <= 1 degrees). Methods. We observed red clump stars in four fields along the bar's major axis (l = 10 degrees, -6 degrees, 6 degrees and b = 0 degrees plus a field at l = 0 degrees
