装配式双梁多柱节点框架试验和数值模拟

为研究水平静力荷载下不同角件节点传力特点,以某拟建新型装配式组合轻体板结构住宅工程为研究背景,取其两层一跨平面结构体系为试验原型,设计了包括L型、T型、十字型和灌浆L型4种节点的足尺框架模型的水平静力加载试验,对不同节点形式钢框架的工作性能与破坏特征进行研究,并与ABAQUS数值模拟进行对比验证.根据试验和数值模拟结果,得出了不同节点框架的初始刚度和极限荷载,以及不同截面位置上的应变值.结果表明:新型轻体板结构角件节点连接性能良好,钢框架发生梁铰破坏,节点部位完好,满足“强柱弱梁”与“强节点弱构件”的设计要求；T型节点双柱协同性能较好,L型、十字型节点的柱子易发生变形；节点小斜撑提高了钢框架初始刚度的38%,节点灌浆提高了钢框架初始刚度的14%,双梁完全独立工作,多柱不完全独立工作,通过应变分析与理论推导提出了双梁多柱的等效抗弯刚度计算方法,数值模拟与试验吻合较好,验证了结论的正确性.

STORY GENERATION BASED ON DYNAMICS OF THE MIND

A story generation system based on dynamics of the mind is presented. Semantic theories until now avoided discussing a linkage of language with encyclopedic human knowledge. This paper attacks the problem of how to make clear the complicated, wide-ranging dynamics of the mind and how to connect it to language.
First, the background of this study is shown, in which our model of the mind, with both five levels along the concept formation process and eight domains according to the contents of mental activities, is surveyed.
Based on this model, then, the dynamics of mind are discussed, along an Aesop fable. A unit of data processing in the mind is called a "module," and the mental dynamics are considered as a chain activation of those modules, represented by a dynamic network. Next, a method for story generation is discussed. Propositional information of a sentence is embedded in a slot of activated, frame-structured modules, and the discourse structure of a generated story basically depends on the dynamic network. Both the chain activation and the generation processes are verified by experiments.
Lastly, residual problems of our research, a comparison with related research, and its applications are discussed.
This case study would be expected to give a basis to integrated systems for problem solving, natural language and image understandings, their generations, and intelligent robots.
