中文拼音 [héngchēngtiáo]
桁撐條
英文
girder stay-
A horizontal beam, as of steel or wood, used as a main support for a building or bridge
大樑一水平的鐵制或木製的桁條，用來作為建築物或橋梁的主要支撐物During the transverse analysis, as the discussion of frame bracing condition that exists in the new vision < code for design of steel structures > gb50017 - 2002 has been lead into the stability analysis of staggered truss system, the concept of strong and weak bracing staggered truss system, and the concrete dividing standard are also given, so that makes the staggered truss stable theory have a good link with the new code, and provide theory guarantee for designers
橫向分析時將我國新修訂的《鋼結構設計規范》 gb50017 - 2002中，關于框架體系支撐條件的論述引入到錯列桁架的穩定分析中，提出了強支撐錯列桁架體系和弱支撐錯列桁架體系的概念以及具體的劃分標準，使得錯列桁架的穩定分析可以與新規范很好的對接，為設計人員的使用提供了理論保障。The paper carried out elastic response spectrum analysis on staggered truss frame system, input two strong ground motion records to carry out elastic and plastic time - history analysis. the paper compared the difference of aseismic property between 20 - storeyed composite truss and 20 - storeyed braced composite truss, and concluded that longitudinal brace can not only increase the rigidity but also reduce drift displacement of the first storey. in addition, the paper adopted displacement coefficiency in push - over method to obtain object displacement, and gave the failure modes of the two structures respectively
本文對鋼結構交錯桁架體系進行了彈性反應譜分析、輸入了兩條強震記錄進行彈性以及彈塑性時程分析，對比了20層混合式和20層縱向帶支撐混合式在彈性階段及彈塑性階段的抗震性能區別，得出縱向帶支撐不但有利於增大縱向的剛度，還可以減小結構底層層間變形的結果；利用pushover的位移系數方法得出了結構的目標位移，並得出了兩種結構的破壞模式。
