Galvanized steel z profile are the structural means used in many architectural designs today. Compared with high-rise reinforced concrete structures, hot-dip galvanized Z-beams are generally softer in high-rise steel structures, and have a larger lateral displacement value under wind loads and earthquakes. If the building has a large swing under the influence of gusts Or reverse, will have a great impact on the human body’s feelings, often make people feel uncomfortable, and sometimes even intolerable, the human body is sensitive to wind vibration acceleration, in order to ensure that the high-rise steel structural engineering building has a good work under the wind in the living environment, it is necessary to limit the acceleration parallel to the direction of the wind load and the direction perpendicular to the wind load.
When the lateral deformation of a building under wind load or multiple earthquakes is too large, it will cause damage to the building decoration materials and damage of non-structural members, resulting in residual deformation in the steel structural engineering components. In the case of earthquakes, if the deformation of the steel structure works, it will cause great effects, and the serious damage of the non-structural components will also cause personal injury.
Like other cold-formed steels, the problem in the production process of hot-dip galvanized Z-shaped steel is the problem of internal stress. Due to the large internal stress of the material, once it is put into use, it may be deformed, which may affect its use.
