Numerical Determination of Shear Strength of Steel Reinforced Concrete Column Strengthened by CFRP Sheets

The earthquake-resistant property of reinforced concrete members depends on the interaction between reinforcing bars and surrounding concrete through bond to a large degree,In this paper a general system aimed at dealing with the failure analysis of reinforced concrete columns strengthened with carbon-fiber-reinforced plastic(CFRP) sheets including bond-slip of the anchored reinforcing bars at the foot of the columns is presented.It is based on the yield design theory with a mixed modeling of the structue,according to which the concrete material is treated as a classical two-dimensional continuum ,whereas the longitudinal reinfocing bars are regarded as one-dimensional rods including bond-slip at the foot of the columns,In shear reinforced zones both the shear CFRP sheets and transvers reinforcing bars are incorporated in the analysis throuth a homogenization procedure and they are only in tesion ,The approach is then implemented numerically by means of the finite-element formulation,The numerical procedure produces accurate estimates for the loading-carrying capactiy of the shear members taken as an illustrative application by correlation with the experimental results,so the proposed approach is valid.

经营者激励报酬契约中业绩评价指标的选择

激励报酬契约是解决委托人与经营者之间“激励不相容”问题的重要手段,而其关键在于选择科学,合理的业绩评价指标。传统业绩评价指标一净收益和股价相结合的激励报酬契约并没有起到理想的激励效果,以EVA和MVA有机结合的业绩评价指标选择应该是更为科学的经营者报酬契约设计。     

2-甲基丙烯醛与1,3-丁二烯的Diels-Alder反应的理论研究

运用密度泛函理论对2-甲基丙烯醛与1,3-丁二烯之间的反应进行了理论计算,计算结果表明反应碳-碳键的形成是同时、不同步进行的。     

法律约束与指环之爱——莎士比亚《威尼斯商人》指环隐喻研究

指环在西方文化中的重要性众所周知。在《威尼斯商人》中,波西亚在与巴塞尼奥结婚后,表达了自己的忠诚．那个戒指是他们婚姻与爱情的象征。同样．夏洛克也把妻子给他的指环当成了命根。因此,对于他们来说,指环意味着一种爱、一种责任、一种束缚。莎士比亚灵活自如地让此剧的种种矛盾冲突一一化解,最后以大团圆收场。但由始至终．他都在暗示一个不言而喻的真理：法律在构建一个和谐社会中的重要地位。不论指环还是法律．都可以用“约束”一词加以概括。约束可以是一个圆圈就像指环一样,也可以是法律,因为它们有着同样的功效。     

参考点效应理论应用于巨灾债券定价的研究

现有的巨灾债券定价模型是基于标准金融理论建立的。本文认为,应综合运用标准金融理论与行为金融理论对巨灾债券定价加以研究,尤其要重视参考点效应理论的运用。本文就巨灾债券定价研究范式、参考点效应理论在巨灾债券定价研究中的运用、巨灾债券定价过程中参考价格的形成展开分析,希望本文的工作能有助于相关研究的开展。     

氢键缔合水分子与水的反常膨胀探析

从水的密度、水分子结构、冰的结构、水分子间的氢键及水分子的缔合等入题,分析了对水的反常膨胀;从微冰结构、晶体结构、极性分子及分子缔合几种解释方法,认为用水分子间形成氢键缔合水分子理论解释水的反常膨胀最为科学,与实验事实及晶体理论相吻合。     

浅谈如何判断单核分子或离子中的π键的类型

π键是分子结构中的重要概念。如何判断分子中是否含有π键及其类型是无机化学、有机化学和结构化学中的一个值得研究的问题。本文介绍一种如何判断单核小分子或离子中的π键类型的方法。     

An Examination of Perceived Therapeutic Bond as a Mediator of Psychological Outcomes

The client's perception of the therapy relationship is an essential component of modern theoretical orientations. To date, there is a lack of quantitative research examining how the therapeutic bond affects therapy outcomes in college counseling. This study used path analysis to examine longitudinal therapy outcomes with 423 college students. Having a stronger therapeutic bond predicted decreased symptoms of depression, social anxiety, and academic distress. Findings support continued attention to developing a working relationship.
