Steel structure has long been a widely used material in many manufacturing and construction projects. Steel structure can be steel bridge, prefabricated steel structure plant, ocean structure, heavy steel structure unit, exciter, material treatment structure and almost all components.
Although studies and discussions have addressed issues such as cost, strength and durability, and installation speed, many people still doubt the safety advantages of steel structures. Steel itself has certain characteristics, its behavior has a positive impact on safety.
Both steel and reinforced concrete form structures that can withstand fire, strong winds, snow, termites and fires. But in seismic performance, steel structure has more advantages than concrete structure.
Steel is light in weight and good in toughness, which helps the structural frame absorb and reduce the damage of earthquake. High-strength steel joints can slightly deform the joints but prevent members from separating, thus preventing buildings or components from collapsing under pressure. According to an article in the New York Times, steel performs better than concrete in earthquake zones. Ultimately, this is why earthquake-prone Japan generally avoids the use of coagulants in tall buildings. Because concrete is hard, heavy, and inelastic.
Steel structures are electrically conductive and well grounded and are not susceptible to lightning strikes or damage. Steel structures allow lightning currents to pass harmlessly through steel components before reaching the ground. Materials with better electrical resistance are more likely to absorb structures damaged by lightning strikes. The steel structure is fitted with proper lightning protection and can withstand up to 10,000 volts of electricity.
The application of steel reinforced concrete column construction scheme can greatly shorten the construction period. It takes less time to form the engineering, which means less time to be exposed to danger. The prefabrication of various steel structure members in controlled environment can not only improve the quality of the members, but also reduce the work at high altitude. The steel pieces are sent to the site as components, so installation can be completed with minimal labor and time.
