For the FRP trussed members, it is worth noting that all of these members were designed initially as pure tension-compression members and were only subjected to the axial direct forces in the preliminary design phase, in which the triangular truss was simplified as a plane truss model.
Based on the pretightened teeth connection, the junction of the aluminum constructional elements with the FRP trussed profiles can be easily realized.
The SHELL63 element was selected for the modeling of aluminum thin plate of the bridge deck, while the BEAM188 element was employed to simulate the crisscrossing "I" beams and trussed members, respectively.
The decay, termite attack, mold, blue stain, and paint on the trussed round-wood members were investigated after long-term exposure to the weather.
This means the flexural properties of trussed round-wood beams were dependent on the strength of both wood members and mechanical fasteners at the joint.
The stresses of critical tension and compression round-wood members of the trussed beam were 39.7 percent and 28.2 percent of allowable design values, respectively.
