轻型钢结构通常用于高层、大跨度、体型复杂、荷载或吊车起重量大、有较大振动、高温车间、密封性要求高、要求能活动或经常装拆的结构。直观的说：大厦、体育馆、歌剧院、大桥、电视塔、仓棚、工厂、住宅和临时建筑等。这是和济南轻型钢结构自身的特点相一致的。

Light steel structures are usually used in high-rise, large-span, complex structures, heavy loads or cranes, workshops with significant vibrations, high temperatures, high sealing requirements, and structures that require mobility or frequent disassembly. Intuitively speaking, buildings, gyms, opera houses, bridges, television towers, warehouses, factories, residential and temporary buildings, etc. This is consistent with the characteristics of Jinan's lightweight steel structure itself.

轻型钢结构通常有框架、平面(木行)架、网架（壳）、索膜、轻钢、塔桅等结构型式。其理论与技术大都成熟。亦有部分难题没有解决,或没有简单实用的设计方法，比如网壳的稳定等。

Light steel structures usually have structural types such as frames, flat (wooden) frames, grid frames (shells), cable membranes, light steel, towers and masts. Most of its theories and technologies are mature. There are also some problems that have not been solved, or there is no simple and practical design method, such as the stability of the grid shell.

结构选型时，应考虑它们不同的特点。在轻钢工业厂房中，当有较大悬挂荷载或移动荷载，就可考虑放弃门式刚架而采用网架。基本雪压大的地区，屋面曲线应有利于积雪滑落（切线50度内需考虑雪载）。

When selecting structures, their different characteristics should be considered. In light steel industrial buildings, when there is a significant hanging load or moving load, it can be considered to abandon the portal rigid frame and use a grid structure. In areas with high basic snow pressure, the roof curve should be conducive to snow accumulation and sliding (considering snow load within 50 degrees of the tangent).

总雪载释放近一半。降雨量大的地区相似考虑。建筑允许时，在框架中布置支撑会比简单的节点刚接的框架有更好的经济性。而屋面覆盖跨度较大的建筑中，可选择构件受拉为主的悬索或索膜结构体系。

Nearly half of the total snow load is released. Similar considerations are given to areas with high rainfall. When the building allows, arranging supports in the frame will have better economic efficiency than simply connecting the nodes to the frame. In buildings with a large span of roof covering, a suspension cable or cable membrane structure system with components mainly subjected to tension can be selected.

高层轻型钢结构设计中，常采用钢混凝土组合结构，在地震烈度高或很不规则的高层中，不应单纯为了经济去选择不利抗震的核心筒加外框的形式。宜选择周边巨型src柱，核心为支撑框架的结构体系。我国半数以上的此类高层为前者。对抗震不利。

In the design of high-rise lightweight steel structures, steel-concrete composite structures are often used. In high-rise buildings with high or irregular seismic intensity, the form of unfavorable seismic resistant core tube and outer frame should not be chosen solely for the sake of economy. It is advisable to choose a structural system with surrounding giant src columns and a supporting frame as the core. More than half of such high-level officials in our country are the former. Disadvantageous to earthquake resistance.

结构的布置要根匀据体系特征,荷载分布情况及性质等综合考虑。一般的说要刚度均匀。力学模型清晰。尽可能限制大荷载或移动荷载的影响范围,使其以直接的线路传递到基础。柱间抗侧支撑的分布应均。

The layout of the structure should be comprehensively considered based on the characteristics of the system, load distribution, and properties. Generally speaking, the stiffness should be uniform. The mechanical model is clear. Try to limit the influence range of large or moving loads as much as possible, so that they are transmitted directly to the foundation through the line. The distribution of lateral support between columns should be uniform.

其形心要尽量靠近侧向力(风震)的作用线。否则应考虑结构的扭转。结构的抗侧应有多道防线。比如有支撑框架结构,柱子少应能单独承受1/4的总水平力。

Its centroid should be as close as possible to the line of action of lateral forces (wind shocks). Otherwise, the torsion of the structure should be considered. The anti side of the structure should have multiple lines of defense. For example, if there is a supporting frame structure, the columns should be able to withstand at least 1/4 of the total horizontal force independently.

框架结构的楼层平面次梁的布置,有时可以调整其荷载传递方向以满足不同的要求。通常为了减小截面沿短向布置次梁，但是这会使主梁截面加大，减少了楼层净高,边柱也有时会吃不消，此时把次梁支撑在较短的主梁上可以牺牲次梁保住主梁和柱子。更多相关内容就来我们网站http://www.jnghbxg.com咨询！

The layout of the secondary beams in the floor plan of the frame structure can sometimes be adjusted in the direction of load transfer to meet different requirements. Usually, secondary beams are arranged along the short direction in order to reduce the cross-section, but this will increase the main beam cross-section, reduce the net height of the floor, and sometimes the top side columns may not be sufficient. At this time, supporting the secondary beam on a shorter main beam can sacrifice the secondary beam to protect the main beam and columns.
