The stress state in certain FRP trussed members and the displacement at the midspan of the lower chord member were abstracted, respectively.
In this section, based on the on-axis four-point loading test that was conducted in previous work [18], the validation of the established finite element model (FEM) was further performed by comparing the numerical solutions with the experimental results, including the vertical displacement at the midspan of the lower chord member and the internal axial direct forces in some FRP trussed members.
Internal Axial Direct Forces in the FRP Trussed Members.
In this section, the numerical results under the two different loading conditions are presented and compared to obtain the dissimilarities of the structural performance, including the vertical and horizontal displacement at the midspan of the lower chord member, the deformation of the HFRP lower chord member, and the stress state of FRP trussed members and the connectors.

The deflection of the trussed bridge continued to increase because of a subsequent typhoon event.
It is suggested that the flexural performance of trussed round-wood beams can be improved when using larger sizes of thinning logs and longer spans based on the span/depth ratio consideration.
