Imagine two 900 triangles back to back with their bases horizontal making a straight line.
The bases are half of the bridge; one of the two sides is supporting the weight of the bridge the other is anchored to a solid point. The weight of the bridge is pulling the apexes of the two back to back triangles downwards; these two vertical sides of the triangles are the supporting column at one end of the bridge. Now imagine a mirror image of what I have described and you will see a suspension bridge.

the first Truss bridge was built by Palmer in 1811 in Philidelphia
you can check this out link below- its about Truss Bridges
Wilson Pratt Truss Bridge was created in 1904.

A truss bridge uses trusses as the load bearing element of the bridge. Using statics physics, a truss bridge applies Newtonian motion to ensure that the load bearing elements do not go out of a tension/compression equilibrium.
A truss is a diagonal brace which provides structural support for a bridge span by extending between a vertical member and the bridge span.
The load capacity of a truss bridge depends on various factors, including the materials used, the design and configuration of the truss, and the specific loading conditions it is engineered to handle. Typically, the load capacity is determined through structural analysis, which assesses how different forces such as dead loads, live loads, and environmental loads (like wind or seismic activity) affect the bridge. Engineers often refer to standards and codes to ensure that the bridge can safely support the intended traffic and loads. Ultimately, the specific load capacity will vary significantly between different truss bridge designs.
I want to build a truss bridge because truss bridge is most economical and his dead load is too low.
not truss
There are many forces acting on a truss bridge compression, tension, and torsion. The truss bridge uses equilateral triangles to spread out the stress of the load on these forces along the hold structure.
Simply put, a truss bridge is just a bridge built by trusses. Trusses are structural frames composed of triangular pieces/joints. So basically a truss bridge is just many triangular structural frames as a support for the bridge.

The weight a truss bridge can hold varies significantly depending on its design, materials, and dimensions. Generally, well-engineered truss bridges can support thousands to millions of pounds, with some large-scale examples designed to carry heavy vehicular traffic. Factors like load distribution, span length, and safety standards also play crucial roles in determining the bridge's load capacity. For precise calculations, specific engineering assessments are required.
