Steel structure will be affected by many external factors in the process of use, such as load, uneven settlement of foundation, temperature and so on. Therefore, steel should have good mechanical properties, strength, plasticity and toughness, which is safer and more reliable.
Steel is light in weight and high in strength; The steel structure has light self-weight and small foundation load. Under the same load condition, its strength is much higher, it can bear more load and span more. It can also reduce the cost of basic engineering and reduce the workload of hoisting and transportation. It is suitable for long-span, towering structures and heavy structures with heavy loads.
Good plasticity, toughness, safety and reliability; Because steel itself has good plasticity and toughness, steel structure is more suitable for vibration load, and the construction calculation of steel structure is accurate, safer and more reliable.
