Besides one h - steel production line , we have three specialized production lines altogether , which can produce the round steel , screw steel , h - beam , channel steel , angle steel , i - beam 我公司下属轧钢厂一个，焊接h型钢生产线一个，共有三套专业生产线，可以生产各种圆钢、螺纹钢、工字钢、槽钢、角钢、 h型钢。
Shear properties in the plane of the panel ( interlaminar shear ) duplicate the kind of shear stress encountered in such glued structural assemblies as structural sandwiches and adjacent to gluelines between ? anges and webs in box - beams and i - beams and gusset plates in trusses 面板表面剪切性能（层间剪切） ，在遇到粘合结构组合例如结构夹层以及靠近于边缘，箱束网和构架盘上三角片间的粘合线时，使剪切应力双倍
Shear properties in the plane of the panel ( interlaminar shear ) duplicate the kind of shear stress encountered in such glued structural assemblies as structural sandwiches and adjacent to gluelines between flanges and webs in box - beams and i - beams and gusset plates in trusses 面板平面的剪切特性（层间剪切） ，与夹层结构这类粘合组件，以及箱形梁、工字梁凸缘与腹板间的焊接层和桁架加固板附近位置所受的剪切应力类型相同。
Adopting the conceptions of thin - walled member theory , studies on linear elastic analysis and ultimate strength behaviors of curved i - beams are presented in this paper , which may give helps to a deeper understanding of the behavior of curved beams and provide a reasonable design guideline 本文依据薄壁构件理论，通过对工字形截面圆弧曲梁的线性分析、稳定理论和极限承载力等问题的研究，旨在进一步了解这类构件的工作特性，并为工程设计提供一定帮助。
