立柱广告牌结构设计要从哪些方面考虑?

荷载和荷载组合结构承受的主要荷载有:1)自重;2)风荷载;3)温度荷载;4)检修活载;5)地震荷载。
Load and load combination structure bear the following main loads: 1) self weight; 2) wind load; 3) temperature load; 4) maintenance live load; 5) earthquake load.
荷载组合有三类:1)基本组合;2)特殊组合;3)施工吊装。
There are three types of load combination: 1) basic combination; 2) special combination; 3) construction hoisting.
应力分析由于钢立柱为压弯构件,其承载力取决于柱的长细比、支承条件、截面尺寸以及作用于柱上的荷载等,计算表明,钢立柱的承载力一般由稳定控制。
Stress analysis because the steel column is a compression bending member, its bearing capacity depends on the slenderness ratio, supporting conditions, section size and the load acting on the column. The calculation shows that the bearing capacity of steel column is generally controlled by stability.
上部结构的主梁可简化为刚结或铰结在钢立柱上的悬臂结构,主梁之间由横梁及斜撑铰结形成空间平行组合桁架。内力计算采用有限元程序在计算机上完成。
The main beam of the superstructure can be simplified as a rigid or hinged cantilever structure on the steel column. The space parallel composite truss is formed by the beam and diagonal brace hinge between the main beams. The calculation of internal force is completed by finite element program on computer.
根据钢结构设计理论,对接焊缝在截面不减小的情况下,其强度可达到母材的强度,因而无需验算焊缝应力,但应严格检查焊缝质量及饱满度。上部桁架杆件间的连接主要是角焊缝。
According to the design theory of steel structure, the strength of butt weld can reach the strength of base metal without reducing the cross section, so it is not necessary to check the weld stress, but the weld quality and plumpness should be strictly checked. The connection between upper truss members is mainly fillet weld.

焊缝承受杆件间的应力传递,其受力大小已由上部结构计算得出,对单立柱广告牌之类结构,上部结构杆件受力一般不大,为施焊方便,可用围焊,并统一取焊脚尺寸为hf=10mm,可满足规范要求:但对广告牌面板骨架与主骨架挂点处焊接须逐一核算。
The welding seam bears the stress transfer between members, and the stress magnitude has been calculated by the upper structure. For the single column billboard and other structures, the upper structure members are generally not stressed. For the convenience of welding, the welding leg size is HF = 10 mm, which can meet the requirements of the specification. However, the welding of the hanging point of the billboard panel skeleton and the main framework must be calculated one by one.
