中文摘要
一般来说,我们仍然有一个困难,在数值上再现的响应的结构,其中的局部变形,如屈曲的钢筋。因此,本研究的最终目标是开发由具有常规本构律的标准单元和通过单独进行的单元实验获得响应的专门开发的单元组成的分析方法,并提出在构建上述系统时必不可少的新分析方法和新设计方法。(1)分析与实验系统间通信协议的原型开发考虑到大规模规模、分布/并行环境和数据的可扩展性,通信协议的开发使用了所谓的文档系统。所采用的通信协议在小型局域网中进行了测试, 关于我们 o对非线性程度适中的系统进行工作。(2)随机无单元法的发展为了使材料的不确定性和复杂的钢筋混凝土结构的建模变得容易,本文发展了一种随机无单元法。该方法是将无网格伽辽金法推广到微扰展开法和多项式混沌法中的一种。通过与各种边界条件下的Monte Carlo模拟结果的比较,证明了该方法的正确性和有效性。(3)自质量调整虚拟材料模型的开发对于地下钢筋混凝土结构的连接部分和边缘部分,采用了可自动生成配筋的自质量调整型虚拟材料模型。根据计算结果,可以得到一种可实际应用的、能承受一定程度的弯剪荷载的设计模式。值得注意的是,当考虑剪切破坏的尺寸效应占主导地位的大尺寸构件时,本方法变得更加有效。少
英文摘要
In general, we still have a difficulty in numerically reproducing a response of the structure in which a localized deformation, such as a buckling of reinforcement steel. Hence, the final goal of the present research was to develop the analysis method which is composed of a standard element with conventional constitutive law and a specially developed element in which responses are obtained through an element experiment separately conducted, and to suggest a new analytical method and new design method which become indispensable when building the above-mentioned system. The research result enumerated below :(1)Development of prototype to the communication protocol used between analysis and experiment systemsThe development of the communication protocol was carried out using so-called Document system in consideration of large-scale sizing, distribution / parallel environment and extendibility of the data. The adopted communication protocol was tested within small-scale LAN, and is found t … More o work for the system in which the level of nonlinearity is moderate.(2)Development of Stochastic Element Free MethodFor the purpose of making it possible to model easily not only the indefinite nature of the material but complicated RC structures, an stochastic element fee method is developed. The method is developed by extending the element free galerkin method by either perturbative expansion method or Polynominal Chaos. By comparison with the result of the Monte Carlo simulation in various boundary conditions, the validity and effectiveness of the technique are demonstrated.(3)Development of self mass adjustment virtual material modelTo the junction part and edge part of subterranean ferro-concrete structure, a self mass adjustment type virtual material model, in which reinforcing bar arrangement can be automatically generated, is adopted. From the result, it can be obtained, a design pattern which can be actually applied and which can sustain bending and shear force, with suitable degree. It is notable to say that the present approach becomes more effective when the large-sized component, in which the size effect of shear failure becomes dominant, is considered. Less
