异形柱住宅结构,因其具有柱肢厚度与填充墙相等,室内没有柱楞突出,便于装修和家具布置,增加实际使用面积等优点,得到广大用户和开发商的青睐。但是普通钢筋混凝土异形柱具有延性差、承载能力有限、梁柱节点布筋复杂,不利于施工等弱点,使其应用受到了一定的限制。型钢混凝土异形柱继承了型钢混凝土承载能力高、延性好的优点,同时能克服钢筋混凝土异形柱的不足,因此,有望在住宅结构中发挥重要作用,应用前景广阔。本文主要介绍型钢混凝土异形柱的特点及国内外的研究现状,提出型钢混凝土异形柱推广应用亟待解决的问题。
Abnormal column residential structure, because of its column limb thickness and fill the same wall, there is no columnar protruding interior, easy decoration and furniture layout, increase the actual use of the advantages of area, the majority of users and developers of all ages. However, ordinary reinforced concrete special-shaped columns with poor ductility, limited load capacity, beam and column nodes tendons complex, not conducive to construction and other weaknesses, its application has been subject to certain restrictions. SRC special-shaped columns inherit the advantages of high carrying capacity and good ductility of SRC and can overcome the shortcomings of SRC-shaped columns. Therefore, it is expected to play an important role in residential structures and has broad application prospects. This paper introduces the characteristics of SRC special-shaped columns and the research status at home and abroad, and puts forward the problems to be solved urgently to promote the application of SRC special-shaped columns.
