Another problem is time - delay being in the control of mr structure , hi this paper , one input of the fuzzy logic controller is the seismic acceleration that avoids some time - delay being in the control . but time - delay being in the structure still is n ' t solved , so the neural network technique is introduced to predict the seismic responses of structures to avoid it , and the bi - state neural network control and fuzzy full - state neural network control are proposed . 4 对于磁流变阻尼结构控制中的时间滞后问题，本文将地震加速度作为模糊逻辑控制器的一个输入，消除了控制中部分滞后问题；但仍存在着结构本身的滞后问题，对此引入神经网络对建筑结构的地震反应进行预测，并基于预测的动力反应和实测结构的动力反应的综合值作为模糊逻辑控制器的输入来消除建筑结构本身的时滞，并提出了双态神经网络控制和模糊全态神经网络控制； 4
Multi - towers structure with transfer story , which is liable to satisfy the architectural function that small space should lay at the top of the building while big space on the bottom , have been applied widely , but methods and experiences about structural design of such complex tall building are absent at present and the relative regulations in the code are not definite and not liable to operate 多塔带转换层结构因易于满足上部布置小空间、下部布置大空间的建筑使用功能的要求而得到越来越广泛的应用，但目前国内外对这种复杂高层建筑结构的设计还缺乏经验，现行规范的相关规定多是笼统和原则性的，可操作性较差。
The thought of intelligent structure was brought forward by the researcher in the field of civil engineering , because it can expend basically the function of the building structure and meet extremely human need for the safty - trut of the living space . therefore , undoubtedly intelligent structure has become a new development direction for the future civil engineering structures 智能结构是近年来业内人士的一个热点话题，由于它使建筑结构的功能从根本上得以扩充，能极大地满足人类对生活空间的安全信任需求，因此，智能结构已毫无疑问地成为未来土木工程结构的发展方向。
In general , some practical and useful fitting equations are deduced after researches on static and dynamic tests of composite cemented clays and corresponding regression analysis , which can be referred at the shortage of test data . the dynamic interaction between composite cement pile foundations and structures as well as the seismic settlement of superstructures are analyzed with the conversed seismic acceleration pr 将地震曲线进行反演施加于基岩表面，通过对水泥搅拌桩复合地基和上部建筑结构动力相互作用以及建筑结构的震后变形的分析研究，得到了一些对抗震设计有意义的结论，为今后累似工程合理地进行地基处理和结构抗震设计提供了良好的参考作用。
Because short fibers have higher tensile resistance and ordinary concrete has higher compressive strength in the process of loading , every technical property of fiber reinforced concrete is improved greatly . accordingly steel fiber reinforced concrete has better stressing properties such as crack resistance , bending resistance , anti - fatigue , anti - friction and high toughness . so it has brilliant future in highway surface , road surface of aerodrome and architectural construction 在受力过程中,短钢纤维发挥其抗拉强度高,而混凝土发挥其抗压强度高的各自优势,从而使其具有优良的抗裂、抗弯、耐疲劳、耐磨耗、韧性高等力学性能,在公路路面、机场道面及建筑结构的应用上有着广阔的前景。
It ' s an ideal structural system and has multi - earthquake resistance ability because of a great deal of slabs removed in floors above the transfer - story amended the lateral stiffness of the stories near the transfer - story . based on the available references , the five - spring line element , the three - spring line element and the multiple vertical - line - element model are introduced to model special column , beam and shear - wall , the relevant stiffness matrixes are deduced and the restoring - force models are gaven to deep into the elasto - plastic seismic characteristics of the structure . acording to the results of shaking table test and elastic finite element analysis , a new making model melhod is presented in which uses the linear and the nonlinear element and the assumption that the floor is infinitely rigid in different areas 为进一步研究这种复杂高层建筑结构的弹塑性性能，本文在国内外现有研究的基础上，提出利用五弹簧杆元、三弹簧杆元及多竖线单元模型分别模拟空间柱、梁和剪力墙，推导了相应的刚度矩阵并给出了恢复力模型；结合试验研究和精细有限元分析的结论，提出线性和非线性单元相结合，刚性楼板假定和弹性楼板相结合的建模方法，较好地解决了空间结构弹塑性分析中占用计算机资源较多的问题；接力大型有限元分析程序? ? ansys ，在上述建模思路的指导下建立了结构的空间非线性分析模型，进行了空间三维弹塑性时程分析。
