结构的概念设计与创新

目的 通过运用概念设计的方法，指出了钢管混凝土核心柱、异型钢筋混凝土柱、门式刚架节点在设计上的不足，提出了改善其不足的办法．方法 通过对结构基本概念的阐述。运用简单的力学原理和概念设计的方法，分析了钢管混凝土核心柱、异型钢筋混凝土柱、门式刚架节点的受力状态，指出其受力不合理之处．结果 通过分析表明钢管混凝土核心柱和异型钢筋混凝土柱及门式刚架节点存在着受力不合理之处，影响了结构的发展和使用．结论 在指出钢管混凝土核心柱和异型钢筋混凝土柱及门式刚架节点设计的缺陷后，提出了新的结构形式，经过初步分析，该新形式更为合理，为工程的应用奠定了基础．

Concept Design and Innovation of Structure

Based on the simple principle of mechanics and the way of concept design,the analyses have been carried out concerning the disadvantages of circular steel tube compile columns filled with reinforced concrete,the application shortcomings of steel reinforced concrete(S.R.C) columns with special cross-section and the problem of joints of portal frame design.At the same time a new method has been suggested to rectify those problems.This is done by means of setting forth the basic concept of structure,making use of the simple principle of mechanics and the way of concept design,analyzing the under-force state of circular steel tube compile columns filled with reinforced concrete and steel reinforced concrete(S.R.C) columns with special cross-section and pointing out the unreasonable points.As a result,the development and application of structure are handicapped because of their weak points.So a new structure type has been brought forward accordingly.The new type is more reasonable and sets a solid foundation for industrial application.
