<p>The lattice girder consists of a series of bars (2,3,4) assembled in triangular configurations by fixed or articulated joints (5), and connecting cables or rods (12,13) in a fan shape between the joints and the opposite sides of the triangles. The upper bars (3), which are mainly subjected to compression forces, are curved in shape, with the center of curvature located on the joint side.</p> |
