Selah Creek, Yakima, Washington
Twin fixed concrete arch highway bridges.Heavy arch ribs designed to resist axial force and bending.Columns and deck not designed to resist longitudinal bending (very flexible).
Gotteron Bridge, Fribourg, Switzerland
Twin fixed concrete arches (supported onrock).
Bending stiffness of arch and deck arecomparable indicating deck is relied uponfor longitudinal flexural moment.
