Steel is a steel structure production-based color steel, is one of the main building structure types. Features steel is a high strength, light weight, good rigidity, strong deformation capacity, so for the construction of large-span and ultra-high, super-heavy buildings particularly suitable; homogeneous and isotropic material is good, is ideal elastomer best serves the general engineering mechanics basic assumptions; material ductility, toughness, and can have a large deformation, can well withstand dynamic loads; construction period is short; its high degree of industrialization round structure, high degree of specialization mechanization produce. Because steel steel at high temperatures and long loads, its breaking strength than the short-term strength decreases more, so the steel under long-term high temperature, to measure the lasting strength. Steel will automatically harden over time, become brittle, or "aging" phenomenon. Steel under low temperature loads To test its toughness.
