大偏心 meaning in English
large eccentricity
Examples
- Compression member with large eccentricity
大偏心受压构件32 - Experiments are conducted to investigate the behavior of 9 columns including 6 strengthened specimens and 3 comparative ones under large eccentric loading
本文对9根大偏心受压柱进行了研究，其中6根为加固柱， 3根为对比柱。 - Experimental results indicate that the strength capacity , stiffness of columns have a certain extent increasing as a result of the action of cfrp , repaired columns " cracks show little and distribute uniformly . the ultimate strength and ductility of column improved due to the transverse strengthening with cfrp and display more distinct benefit when strengthened by the combined action of the longitudinal and the transverse straps of cfrp . in addition , many parameters including anchorage length of cfrp , thickness of cfrp are considered on the effects of cfrp on strength , and failure modes of columns
试验结果表明，大偏心受压柱受拉面纵向粘贴碳纤维布后，偏压柱承载力和抗弯刚度有一定程度的提高，裂缝宽度减小且分布均匀；碳纤维布横向粘贴偏压柱对偏压柱的承载力和延性有一定的提高；纵横向混合粘贴大偏压柱加固效果更显著；混凝土强度低于c20级时，不适合采用碳纤维布粘贴加固。 - Based on plane section assumption , this paper presents the methods of calculating the ultimate strength of the columns strengthened with cfrp , and makes a simplification of the methods . a fortran program on nonlinear method is presented to numerically analyze the characteristics of large eccentrically loaded columns strengthened by longitudinal straps of cfrp , calculating results compare well with experimental data
本文在平截面假定的基础上分别推导了碳纤维布纵向粘贴大偏心受压柱的正截面承载力校核和截面加固基本计算公式，并对公式进行了相应的简化；运用fortran语言编制相应程序对纵向粘贴碳纤维布大偏压柱进行了数值分析，本文公式计算结果和程序计算结果均与试验结果吻合良好。 - The experimental result has shown that the ultimate bearing capacity and ductility of eccentrically loaded columns have a certain increase when they are strengthened with transverse cfrp . in addition , the excessive eccentrically loaded columns have a more notable effect as a result of strengthening with the combination of longitudinal and transverse cfrp . the increasing degree of strengthening columns ’ bearing capacity reduces while the volume of cfrp increases
试验结果表明,碳纤维布横向加固偏压柱时,其承载力和延性均有一定程度的提高;对于大偏心受压柱,纵横向联合粘贴碳纤维布的加固效果非常明显;随着cfrp加固层数的增加,构件承载力的提高幅度减小。
