基于边缘屈服准则装配式屈曲约束支撑分析与设计
|
摘要
基于芯材边缘屈服准则和弯曲屈曲理论,建立装配式屈曲约束支撑极限应力、支撑间隙及芯材截面的计算公式。以十字型芯材支撑为例,分析芯材屈曲半波数对支撑极限应力,支撑间隙和芯材截面的影响。研究结果表明,基于芯材边缘屈服准则和弯曲屈曲理论的分析理论可以合理解释试验和有限元分析结果 ,所建立的相关计算公式可用于装配式屈曲约束支撑的设计中。
Based on the margin yield criterion and the bending buckling theory, these formulae for the limit stress of core, the gap of brace and the section of core, were established. Effect of the buckling half-wave number on the limit stress of core, the gap of brace and the core section was analysed with respect to the cross core section. The results shows that present theory can reasonbly explain the results of test and finite element analysis, and the proposed computation formulae for the brace can be applied to design practice.
