steel structure building has been widely used in various types of basic buildings

nowadays, steel structure building has been widely used in various types of basic buildings because of its good performance. Compared with reinforced concrete structure, steel structure building has good seismic performance and other advantages. However, if the basic requirements of steel structure building design are not followed in the seismic design, the steel structure building will be seriously damaged in the earthquake. Next, what I want to share with you is what are the basic requirements and methods for seismic design of steel structure buildings. First of all, the aseismic performance of steel structure building mainly depends on the selection of structure. The common structural system of steel structure building mainly includes frame structure, frame support structure, frame display furniture for retail stores aseismic wallboard structure, simplified structure and mega frame structure. Then in the architectural design project, we must consider whether the selection is suitable for the surrounding factors, of course, we also need to consider other factors to optimize the scheme design, in the process of optimization, we can determine the appropriate structural system. In the seismic design of steel structure buildings, the maximum height to width ratio is an important parameter of their seismic performance and overall stability. In the design process, it is necessary to follow up the seismic fortification intensity to determine the structure type and the maximum applicable height. In determining the height width ratio, it has a direct impact on the structural stiffness, lateral displacement and vibration form. Height ratio refers to the ratio of the total height of the house to the smaller width of the plane. When the ratio of perfume gift box factory height to width is large, on the one hand, the horizontal displacement and P-A effect of the structure are large, and on the other hand, the overturning moment makes the column produce large axial force. So, the steel structure roomFor the house building, the maximum height width ratio should be limited. Within the reasonable limit, if it exceeds the limit, it needs to be studied again, and some measures should be taken in the seismic design. In the requirements of seismic design, the structural system and layout of steel structure buildings are also very important. For high-rise steel structure buildings, regular architectural design scheme should be adopted in design. If the structure system is complex and the plane and elevation are irregular, it is necessary to set up earthquake resistance joints at appropriate positions, so as to form more regular anti lateral force structural units. Generally speaking, it is not suitable to set anti-seismic joint. When it has to be set, the width of anti-seismic joint shall not be less than store display furniture supplier 1.5 times of the corresponding reinforced concrete structure house. In order to avoid the cracks and even inclinations of the structure caused by the uneven settlement of the building, and to make the structural components enter the plastic area prematurely, the same structural unit should not be set on the foundation soil with different natures, and the natural foundation should not be used partly, and the pile foundation should be used partly; when the foundation has soft weak cohesive soil, liquefiable soil or seriously uneven soil layer, the integrity of the foundation should be strengthened And rigidity. In the selection of construction site, it is necessary to make a comprehensive evaluation of the selected site according to the needs of the project, especially to master the seismic activity and geological related data of the site. It is better to avoid the sections that are unfavorable to the earthquake resistance of buildings than to have soft site soil, liquefiable soil, strip shaped protruding mountain mouth, towering isolated hills, non rock steep slopes, mined out areas, river banks and slope edges. It can choose the open and flat hard site soil, or dense and uniform dry hard site soil and other sites that are favorable for the earthquake resistance of buildings. In order to effectively avoid building torsion and stress concentration or plastic deformation concentration in the earthquake, the layout of building plane and facade should be regular and symmetrical, and the mass distribution and stiffness change should be uniform. If there is no seismic joint, it is necessary to use a calculation model that is consistent with the actual situation. When the seismic joint is set, the building should be divided into regular structural units. First of all, the structural system should have a clear calculation diagram and a reasonable transmission way of earthquake action, have the necessary bearing capacity, deformation and energy consumption capacity, and avoid the loss of seismic capacity of the whole system due to the failure of some structures or components. Measures should be taken to improve the bearing capacity of the possible weak parts. Secondly, in the aseismic structural system, it is necessary to make the structural members and connecting parts have good ductility, avoid brittle failure and improve the overall deformation capacity of the aseismic structure. Therefore, it is necessary to effectively control the size of steel structure members, strengthen the connection between members, and ensure the integrity of the structure. Finally, for the non structural components such as parapet, retaining wall, awning and sealing wall, they should be reliably connected and anchored with the main structure to avoid personal injury and additional earthquake damage caused by collapse during the earthquake; for the connection between the retaining wall, partition wall and the main structure, the main structure damage caused by improper setting should be avoided; the ceiling collapse and falling of heavy suspended ornaments should be avoided, and Reliable measures shall be taken when it can be avoided.
