cross-sectional dimension
解釋
橫斷面尺寸-
In order to study how the floor stiffnesses influence on the mega steel - frame structures, the results of mode 1 and mode 4 of example 1, and those of mode 2 and mode 3 of three examples are compared. some conclusions are obtained as follows : compared with beams and columns of the common steel - frame structures, the cross - sectional dimension of mega beams and mega columns in the main - frames of mega steel - frame structures are very large. because the mega structure system has great lateral stiffness and entirety work behavior, whether or not considering the floor stiffness has less influence on the entirety responses of the mega steel - frame structures and on the displacement and internal forces of columns of the mainframe, but larger influence on the response of columns of hypo - frame
通過對算例1方案1和方案4及算例1 - 3方案2和方案3結構周期、位移和內力反應的比較，研究了樓板剛度對巨型鋼框架結構反應的影響，得到如下結論：與普通鋼框架的梁、柱相比，巨型鋼框架中主框架的巨型梁、巨型柱截面尺寸要大得多，並且由它們組成的這種超常規的大型結構具有巨大的抗側剛度和整體工作性能，因此，在地震作用下，考慮樓板剛度與否對巨型鋼框架結構整體反應影響不大，對主框架柱位移和內力反應影響也不大，但對次框架位移和內力反應的影響相對較大。 -
The cross - sectional size of the pbg cover is greatly reduced and its dimension is only 145 mm x 145 mm ( which is about 2 / 3 smaller than the cover designed by thevenot et al., and 6 / 7 smaller than the one designed by qiu et al. )
該覆層結構還大大縮小了尺寸，其橫截面尺寸只有145mm 145mm ，該尺寸比thevenot等人設計的覆層減小了約2 3 ，比qiu等人設計的覆層減小了約6 7 。 -
Reasons : firstly, sectional dimension is so little that torsional stiffness of single - beam is n ' t enough. secondly, protective layer thickness is too thin to protect concrete reinforced bar and reduce durability. lastly, each main beam is joined by cross girder and the more rigid of cross girder the more entirety of bridge
橋梁局部損壞較嚴重，主要原因是主梁截面尺寸過小、肋板過于薄弱，造成單梁抗扭剛度不足；保護層厚度不夠導致鋼筋外露引起銹蝕，降低了橋梁的耐久性；各主梁採用橫隔梁連接成整體，橫隔梁的剛度越大，橋梁的整體性越好，但調查結果顯示，實際情況中並不能達到理想的整體剛度。
