What are the limitations to the design of the truss bridge?

A truss type bridge is a configuration based on mathematics. The loading, or forces ( including the dead weight and live loads) are distributed through the members ultimately to the bridge supports. The type bridge could be built of any material, from wood to Concrete, or steel. Schools normally have contests for students to build bridges out of balsa basswood. So, the loading, the materials and the method of connecting govern. The limits are in the materials and connections. The student bridge could be built of steel instead of balsa wood, with the right connections that bridge would carry more load than the balsa wood.
