支撑杆

Iron production was revolutionized in the early eighteenth century when coke was first used instead of charcoal for refining iron ore. Previously the poor quality of the iron had restricted its use in architecture to items such as chains and tie bars for supporting arches, vaults, and walls.

Main conclusions of this paper are listed as bellows: First hinge line is not particular in the complete-system, but the close bar on it will generate great stress while the initial stress is imported. So the structural shape has not only great relations with the position set of the hinge line, but also maximum impacts on the deformation of the whole body. Equal to the support part of jacks, the circumference of the fist hinge line will generate the greatest impacts while exchange.

本文研究的主要结论有：第一铰线在完成系中没有特殊之处，但在初期应力导入时，第一铰线上的闭合杆件会产生相当大的应力，因此，结构形状和铰线的位置的设定有很大关系，对结构整体变形也有最大的影响；第一铰线的周边相当于千斤顶的支承部，在替换支撑拆除千斤顶时会产生很大的影响。
