Methods of assembling stiffened composite structures are disclosed. Some methods include forming a stiffener assembly by compacting it within a trough formed in a trunnion. A single trunnion may accommodate two or more different types of stiffeners, thereby avoiding the need for multiple sets of tooling. In some methods, a plurality of stiffener segments may be spliced together, thereby avoiding the need to transport and handle an entire stiffener. A vacuum chuck may be utilized in some examples to transfer the stiffener assembly from the trunnion to a transfer tool. The same vacuum chuck may be transferred along with the stiffener assembly on the transfer tool and loaded onto an inner mold line layup mandrel, where the vacuum chuck may be used to compact the stiffener assembly to the inner mold line layup mandrel.
