Through the low cyclic load test of eight high strength concrete-filled square steel tubular columns, considering the effect of the axial compression ratio, steel ratio and slenderness ratio, the hysteretic curve, ductility, degradation of stiffness, energy dissipation capacity, failure mechanism and characteristics of the specimens were researched.

摘要］以轴压比、含钢率和长细比为参数，进行了8根方钢管高强混凝土柱的低周反复荷载试验，研究分析了该类构件的滞回曲线、延性、刚度退化、耗能能力、破坏机理和破坏特征；并与型钢高强混凝土柱的受力性能进行了比较分析。

The parameters used in the analyses include rise to span ratio, slenderness ratio, steel ratio and load conditions.

分析的参数有矢跨比、长细比、含钢率以及加载方式。

As a compress-bend structure, with increasing of the span, length slender ratio and carrying load of arch increase, lateral rigidity and width span ratio of arch ring minish relatively. During construction and service stages, lateral stability becomes more important and a control factor of arch bridge design.

拱肋作为压弯结构，随着跨径的增大，杆件的长细比及所承受的荷载也随之增大，拱圈横向刚度、宽跨比相对减小，在施工阶段及使用阶段横向稳定问题特别突出，常常成为拱桥设计的控制因素。

As a structure that is compressed and bended, with increasing of the span, length slender ratio and carrying load of arch increase, lateral rigidity and width span ratio of arch ring minish relatively. During constructing and bring to bear, lateral stability becomes especially severity and a control factor of arch bridge design.

拱作为压弯结构，随着跨径的增大，杆件的长细比及所承受的荷载也随之增大，拱圈横向刚度、宽跨比相对减小，在施工阶段及使用阶段横向稳定问题特别突出，常常成为拱桥设计的控制因素。

This requirement ensures that the slenderness ratio of the individual Csection between connectors is less than or equal to one-half of the slenderness ratio of the entire compression member in the case that any one of the connectors may be loosened or ineffective.

这个要求确保在任一连接件可能松脱或失效的情形下，单段U型钢的长细比小于或等于整个抗压构件长细的二分之一。

The results show that the most remarkable factor is the slenderness ratio, the axial compression ratio takes second place and the steel ratio is third.

结果表明，对其影响最大的为长细比，其次是轴压比，再次是含钢率。

By testing the bearing capacity of 6 steel reinforced high-strength concrete columns,the influence of different slenderness ratio on behaviors of the columns was analyzed.

通过6根钢骨高强混凝土柱的承载力试验，分析了长细比对柱受力性能的影响，由试验得出钢骨高强混凝土长柱的承载能力随试件长细比的增大而降低，随混凝土强度等级的提高而提高，破坏的突然性随长细比的增大而愈加明显

Based on this, the stability bearing capacity of steel reinforced high-strength concrete long columns were studied by changing slenderness ratio, the strength grade of

根据试验和理论分析，得出钢骨高强混凝土长柱稳定承载力随着长细比的增大而降低，随着混凝土强度等级的提高而增大；偏压柱承载力随着初始偏心距的增加而降低。

With Newton-Raphson and arc-length calculation method, this paper has made research on effect of various cable style, rise-span ratio and slenderness ratio on ultimate bearing capacity.

文中使用牛顿—拉弗森法和弧长法对荷载—位移平衡路径进行跟踪研究，研究了索对结构极限承载力的影响；分析中考虑了不同矢跨比和长细比等因素对索—拱结构极限承载力的影响。

Total of 16 CFST dumbbell shape d columns subjected to eccentric loads were tested with variation of slenderness ratio and eccentricity ratio.

共进行了10根不同长细比的钢管混凝土哑铃形轴压长柱(5根强轴向破坏，5根弱轴向破坏)的试验研究。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
