【摘要】 智能结构是一种仿生结构体系，它集主结构、传感器、驱动器于一体，具有结构健康自诊断、自监控、环境自适应以及损伤自愈合自修复的生命特征及智能功能。智能结构的诞生是信息学科与工程及材料学科相互渗透融合的结果。近20年来，随着经济的迅猛发展，科学技术的不断进步，高层建筑依据其各种优势如雨后春笋般的发展起来。如果能将智能材料用于高层建筑中，无疑将促进高层建筑和智能材料的发展。本文研究智能平面框架结构分析的新方法，即智能QR法。通过将平面智能框架样条离散化，建立单元节点向量与样条节点向量的关系，根据智能变分原理，建立智能单元样条离散化总势能泛函，进而建立智能框架样条离散化总势能泛函，根据瞬时变分原理，建立智能框架样条离散化方程。本文利用QR法建立了智能高层框架结构分析新的计算格式，指出了QR法与有限单元法相比的优点，用MATLAB辅助编程计算了平面框架，与有限元分析软件ANSYS的结果比较，证明了QR法的有效性及精确性。经过算例分析，获得一些有益的结论。更多还原

【Abstract】 The intelligent structure, which has life characters and intelligent functions,such as health self-monitoring, self-acclimatization and destructionself-repairing of the structures and could self-protect when dangers happen, is akind of bionic structural system. It integrates basic structure, sensor, and actuator.The birth of the intelligent structure is the integration of the information andmaterial science and engineering. In the recent twenty years, with the rapiddevelopment of economy and the continuous advancement of science andtechnology, the high-rise building develops fast by much dominance. It will beundoubtedly accelerate the development of the high-rise building and theintelligent material if the intelligent material can be used in the high-risebuilding.The main content of this paper is the new method of the intelligent planeframe analysis, which is the QR method. It establishes the relationship betweenthe element node vectors and the spline node vectors by making the intelligentplane frame spline disperse and establishes the intelligent element spline dispersing total potential energy functional by intelligent variation principle, andthen builds up the intelligent frame spline dispersing total potential energyfunctional. In the end, according to instantaneous variation principle, itestablishes the intelligent frame spline dispersing equation. This paperestablishes the new calculation format of intelligent high-rise frame structureanalysis, points out the advantage compared to finite element technique,calculates the plane frame by MATLAB, compares the result that calculated byANSYS and approves the effectivity and precision of the QR method. After theoutcome analysis, we get some favorable conclusions from this paper.更多还原
