H-shaped steel is the most commonly used steel material in front of shopping malls. Compared with ordinary steel, what kind of wind characteristics does H-shaped steel have? Compared with I-beams, they have higher structural strength and larger section modulus. When the bearing requirements are the same, metal can be saved by 10-15%. The design style is agile and rich. At the same height as the beams, the openings of the steel structure can be 50% larger than the openings of the concrete structure, which makes the structural layout more flexible.
The structure is lightweight. Moreover, the concrete structure has a lighter self-weight, which reduces the weight of the structure and reduces the internal force of the structure. It can meet the requirements of low construction structure, light construction, and reduced costs. Useful areas to supplement the structure. Compared with concrete structures, steel structure columns have a small cross-sectional area, which can supplement the effective utilization area and increase the effective utilization area by 4-6% depending on construction differences.
High structural stability. The steel structure based on hot-rolled H-shaped steel has reasonable structure, good plasticity and flexibility, and high structural stability. It is suitable for building structures with large vibration and impact loads. It can resist natural disasters and is particularly suitable for belt structures produced by certain ground sports. According to statistics, among the causes of disaster land damage of level 7 or above in the country, steel structure construction, mainly H-shaped steel, is the smallest.
