What are reinforcing structures?Show answer
Beyond triangulation, structures are strengthened by: using a larger or hollow cross-section (a tube or I-beam resists bending well for its weight), adding webs or gussets at joints, folding or corrugating sheet material to stiffen it, and choosing materials with the right properties (strong in compression for struts, in tension for ties). The aim is maximum strength and rigidity for minimum material and weight.
