在18世纪你可以把海盗系在桁杆上吊死。
介绍了神钢7100履带吊臂杆桁杆的修理过程,提出臂杆更换中的注意要点,为起重机臂杆桁杆修理提供借鉴。
This paper introduces the overhaul procedure of Shengang7100 crawler-type crane boom trussed pole, proposes the attention point during exchanging the crane boom trussed pole.
整个结构划分为若干组合单元,每个组合单元包括拱、桁梁及竖杆横撑架三部分。
The structure is resolved into several compound elements and every compound element consist of three parts: arch, trussed beam and lateral brace.
为了使上层公路桥面板能帮助主桁上弦杆抵抗巨大的纵向压力,正桥全部采用混凝土桥面板与钢桁梁共同作用的板桁结合梁。
In order to let the slabs help the top chords of the steel trusses resist the giant compressive forces, slab truss composite structures are used throughout the main bridge.
结果表明:在钢桁梁桥弦杆内填混凝土能降低杆件的应力水平,提高桥梁的整体刚度。
The results show that the stresses of chord members of partially concrete-filled steel truss bridge are decreased, while its integral stiffness is increased.
在帆面的上方是一根短的圆杆,称为斜桁(gaff),使得帆面可以在第四条边上延长,因而比同等高度的三角帆面积更大。
At the top of the sail is a short SPAR called the gaff, which allows the sail to extend back along a fourth side, gaining size over a triangular sail of the same height.
