异形钢管混凝土柱研究综述

THE REVIEW OF THE CONCRETE-FILLED SPECIAL-SHAPED STEEL TUBULAR COLUMNS RESEARCH

异形钢管混凝土结构的特点是柱截面形式灵活,承载力和刚度较大。在建筑中采用异形钢管混凝土结构,可以增大房间使用面积、便于装修、达到美观的的结构设计要求。为使异形钢管混凝土结构更广泛应用于工程,在查阅国内外相关文献的基础上,指出了现行研究中各种截面钢管混凝土柱存在的问题,且总结发现施工复杂是一个较为突出的问题。在此基础上,本文提出了一种新型异形钢管混凝土柱,其施工较方便且加强了钢板和混凝土间的共同作用,在某些方面解决了现有异形钢管混凝土柱存在的问题。异形钢管混凝土结构承载力高、抗震性能好,是结构工程中的一个重要研究方向,势必要逐渐应用到工程实践中。

The advantages of the concrete-filled special-shaped steel tubular structure is that the form of the column section is flexible, and have good bearing capacity and stiffness. The concrete-filled special-shaped steel tubular structure used in the construction can increase the use area of the room, which facilitate the renovation and reach the effect of the beautiful indoor environment. In order to make CFSSST structure more convenient to use in practical engineering, existed problems on CFSSST are analyzed upon related references at home and abroad are summarized, where construction complexity is a prominent one. In this paper a new type of CFSSST is proposed, which is convenient for construction and strengthens the joint action between the steel plate and the concrete. The CFSSST structure has high bearing capacity and good seismic capacity, which is an important research trend in structural engineering, and will gradually be applied to engineering practice.
