Last, The paper studies the result of ANSYS, which mainly includes the loading-displace curve of FSMRCSS under horizontal loads and constant vertical loads, the mechanics of arch under vertical loads lonely and under horizontal loads and constant vertical loads respectively, and status of the distribution and changing of vertical stress and cross shear on the surface of the suporting beam, and the influence of span ratio and hole.All in all, the caculating results are in good agreement with the test results.

本文首先进行了三个1/2比例的两跨两层和一个1/3比例的两跨三层的框支密肋复合墙梁的模型试验，分析了框支密肋复合墙梁在竖向荷载作用下的受力性能，以及在竖向荷载与水平低周反复荷载共同作用下的受力性能、变形性能、滞回性能、耗能系数及破坏形态；其次，研究了混凝土的非线性特性，建立了框支密肋复合墙梁非线性有限元模型，并借助大型通用有限元软件ANSYS进行计算；再则，进行了非线性有限元结果分析，主要研究框支密肋复合墙梁在竖向荷载与水平地震力共同作用下的荷载位移曲线，分析在竖向荷载单独作用下和在竖向荷载与水平地震力共同作用下墙梁的拱作用，托梁顶面的竖向应力和横向剪应力分布及变化情况，并讨论跨度比、洞口对墙梁拱作用和托梁顶面的竖向应力的影响。

Fractography analysis shows that the global tension failures trimly,because of matrix cracks and tension fracture of fiber and the compression specimens failure in a shear plane about a little angle to the compression loading direction because of delamination and longitudinal fiber shear fracture.

其拉伸断口较为平齐，基体开裂以及纤维拉伸断裂是主要破坏形式；压缩破坏呈现剪切断面，压缩断面和压缩加载方向形成一个较小夹角，层间分层和纵向纤维剪切断裂是其主要破坏形式。

There are some aspects undiscussed in this dissertation, for example the contribution of Chinese marketing society should give fuller induction; more systematical analysis should be considered when we analyse the leading causes of the enterprise marketing management failure.

在这种新形势下，企业应该重视与本国社会环境的关系和与国外社会环境的关系，在企业营销管理中，应该贯彻绿色营销观念，这是正确处理与社会关系的具体体现。（第8章）本文研究中还存在一些不足之处，如对中国市场营销学界的理论贡献概括不够全面；对造成中国企业经营失误的原因分析还不够系统等等。

In a probabilistic analysis of unrepairable systems, system behavior is described by reliability and mean time to failure, in which the reliability is defined by the probability of the random event "system is functioning at time t", and MTTF the expected value of random lifetime of system.

衡量不可修系统可靠性的指标主要是系统可靠度和平均寿命。其中系统可靠度定义为不可修系统在t时刻仍正常工作的概率，平均寿命定义为不可修系统寿命的期望值。

The stability of them has an vital influence on project implementation,which is also hand in glove with discontinuity surface, for example,joints,fissure,fault and weak interbed etc.These discontinuity intersect vertically and horizontally ,which makes great difference in property between it and integrated rock.On that account,we should do deepgoing research on deformation failure mechanism and stability analysis for rock mass slopes.

节理岩体边坡的稳定性跟边坡中的不连续面的关系密切，如节理、裂隙、断层以及软弱夹层等，这些结构面纵横切割，使得岩体的性质与完整岩石大相径庭，因此，必须对节理岩体边坡的变形破坏机制和稳定性分析作深入的研究。
