The bearing capacity and ductility of eccentrically loaded columns strengthened with cfrp have been researched , based on the test of 9 rc columns 本文通过9根钢筋混凝土柱的试验研究,研究了cfrp加固偏压柱后对其承载力和延性的影响。
The preventive measures for the factors influencing its strengthening effect and safety in the process of the external reinforced concrete column with angle steel encased are analyzed and dicussed initially 对外包钢加固钢筋混凝土柱过程中影响其加固效果和安全性的诸多因素的安全性防范措施进行了初步的分析研究和探讨。
Finally , the problem about beam - column joint is mainly studied and some design methods are suggested in this paper . meanwhile , the author designs the columns on the ground floor of chunliu high - rise building 并以已建春柳高层建筑底层柱为例，进行了试设计，证明用钢骨?钢管混凝土柱取代钢筋混凝土柱，将带来很大的经济效益和社会效益。
( 4 ) a program to calculate the fire resistance of restrained axially - loaded reinforced concrete columns is compiled in this dissertation , and the effects of different parameters such as dimensions of cross section , concrete cover , ( 6 )对基于性能的结构抗火分析及结构抗火设计进行了讨论,并结合本文的研究成果,对我国的钢筋混凝土柱的抗火设计提出了建议。
The results of the truss type src columns test is analyzed , and the aseismic behavior of src column is deeply studied . with the shaped steel in the column , the bearing capacity is largely increased 本文研究了空腹桁架式src柱的试验结果,对src柱的抗震性能作了比较深入的探讨,结果表明配置角钢的桁架式空腹钢骨的劲性混凝土柱,其抗震能力明显高于钢筋混凝土柱。
By on - site experiment to reinforced columns during the construction period , the columns " total strain including shrinkage and creep in construction circumstance was obtained , and curves of strain development was made 本文通过对在建工程的钢筋混凝土柱进行施工期间的包括收缩徐变变形值的现场测量，得到施工条件下钢筋混凝土柱应变发展曲线，其结果具有现实意义。
If the columns are disabled , the whole structure will collapse or overturn . in addition , the research on fire resistance of reinforced concrete columns provide the foundation for study on other rising combined columns such as concrete filled steel tubular columns and steel reinforced concrete columns 另外,钢筋混凝土柱的抗火性能的研究也能为钢管混凝土柱、钢骨混凝土柱等其它新型组合结构柱的抗火性能的研究打下坚实的基础。
While many theories concerning damage forecasting were put foreword , a different model of damage forecasting based on fuzzy probability will be presented in this paper . and it is reasonable to describe a variable like weight coefficient with fuzzy theory . in the end , the validity of the model is demonstrated well in the applications of one - storied brick bent frame column factories , one - storied reinforced concrete column factories , multistory masonry buildings 国内外不少专家学者或研究单位先后提出了各种震害预测方法，本文在此基础上，利用模糊理论，提出了模糊概率的震害预测模型，其模型能够把两类不确定性(一类是随机上的，另一类是模糊上的)有机结合起来，而且对于权重这样一个充满着模糊性的变量，用模糊语言来处理是非常合理的；并应用于对单层砖排架柱厂房、单层钢筋混凝土柱厂房以及多层砖房的震害预测，实践证明此方法是比较精确的。
Based on the analysis of the experiment results , it is regarded that the seismic behavior of the truss src columns is higher than those of rc columns . the steel requirements , the crosswise rod dimension and the welding quantity are the main factor , which influence on the truss type src columns 通过对试验结果的分析，认为配置角钢桁架式空腹钢骨的钢骨混凝土柱的抗震能力明显高于钢筋混凝土柱，配钢率和斜腹杆的大小与焊接质量是影响桁架式空腹钢骨的钢骨混凝土柱的主要因素。
Based on the tests of 23 rc columns , the strength capacity , stiffness of the columns strengthened with cfrp have been researched ; ductility , the distribution of cracks and failure modes of retrofitted columns have been analyzed . this paper investigated the degree of cfrp function on different eccentricities , and discussed the influence to strengthening effect on the basis of different strengthening mode and concrete strength 本文完成了23根钢筋混凝土柱的试验研究，研究了粘贴碳纤维布偏压柱承载力和刚度的变化；分析了碳纤维布粘贴对柱延性、裂缝分布及破坏形态的影响；研究了在不同偏心距下碳纤维布的作用发挥程度；比较了不同粘贴方式和不同混凝土强度对加固效果的影响。
