既细又高以接受风荷载为主的钢构造称为钢结构工程,首要用做各种塔架和桅杆.
Steel structural engineering refers to steel structures that are thin and tall and mainly accept wind loads. They are mainly used for various towers and masts
钢结构工程归于体型较为细长的构筑物,其构造及受力特色是高度较高,横截面较小,横向风荷载起首要效果.挺拔钢构造主 有自立塔架和接线式桅杆两种构造方式,它们的特色对比挨近,使用范围根本相同,通水把两种构造合在一起称为塔桅构造.
The steel structural engineering belongs to a relatively slender structure, whose structure and stress characteristics are high height, small cross section, and the initial effect of transverse wind load. The vertical steel structure mainly has two construction modes: self standing tower and wiring mast. Their characteristics are closely compared, and the scope of use is basically the same. Tongshui calls the two structures together tower mast structure
钢结构工程自立式塔架构造固定于地上,其力学模型相当于悬臂梁.塔架立面轮廓线可采用直线形,折线型,双曲抛物线形等.接线式桅杆的杆的杆身依托纤绳的牵拉而站立,其力学模型相当于弹性支座接连梁,实腹式杆身多为等截面大型焊接钢管,格构式杆身为三角形工四边形空间桁架.
The steel structural engineering self-supporting tower structure is fixed on the ground, and its mechanical model is equivalent to the cantilever beam. The tower elevation contour can be straight, folded, hyperbolic parabola, etc. The pole body of the wiring mast stands on the pull of the cable rope, and its mechanical model is equivalent to the elastic support connecting beam. The solid web pole body is mostly large welded steel pipes with constant cross section, and the lattice pole body is a triangular I-quadrilateral space truss
