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。 -
Besides, this paper makes nonlinear finite element analysis on concrete - filled crft frame and crft braced frame, then design methods on crft braced frame structure are introduced, proposed values of elastic and elastic - plastic story drift in crft braced frame structure are presented
本文還對方鋼管砼框架和方鋼管砼支撐框架進行了非線性有限元全過程分析，提出了方鋼管砼框架?支撐結構的設計方法，給出了方鋼管砼框架?支撐結構彈性及彈塑性層間位移角的建議限值。 -
On the basis of analysis previous experiment data, it is conclusion that allowable value of drift angle of elastic and elastic - plastic is 1 / 550 and 1 / 75 respectively, which is applicable to r. c. frame structure with special - shaped column is given out. the conclusion explains that the deformabiliry of r. c. frame structure with special - shaped column lies between rectangle column frame structure and shear wall structure. the calculating formula of allowable value of axial load ratio of special - shaped column is derived, it is compared with that of equaling areas rectangle column
根據對前人試驗數據的統計分析，給出了適用於異形柱框架結構的彈性和彈塑性層間位移角限值分別為1 550和1 75 ；指出了異形柱框架結構的層間變形能力介於普通矩形柱框架結構和剪力墻結構之間；以t形柱為例，推導了異形柱軸壓比限值的計算公式，通過與等面積矩形柱的對比分析，認為異形柱的軸壓比限值與其截面尺寸的比例關系有關；當腹板受壓或翼緣受壓時， t形柱軸壓比限值存在較大差異；不同的荷載角作用，軸壓比限值變化較大；矩形柱的軸壓比限值要大於異形柱的軸壓比限值。
