在美国和远东亚洲国家，填充有高强度混凝土的壁厚相对较薄的钢管已经用于建筑结构。这种结构系统允许设计师保持可管理的柱尺寸，同时获得增加的刚度和延性的风和地震荷载。根据建筑限制的要求，柱造型可以采用管或管道的形式。此外，型钢的车间制造有助于确保质量控制。在这种类型的结构中，通常，在每个楼层高度处，重型钢梁被框架连接到这些组合柱。通常，这些连接需要同时发展梁的剪切屈服和塑性弯矩承载力。本文总结了一项试验研究的结果和建议，该研究旨在开发一种抗弯钢连接详图，用于连接钢梁和上述类型的组合柱。该试验研究的重点是具有正方形或矩形横截面的复合柱。
Steel tubes of relatively thin wall thickness filled with high strength concrete have been used in building construction in the U.S. and Far East Asian countries. This structural system allows the designer to maintain manageable column sizes while obtaining increased stiffness and ductility for wind and seismic loads. Column shapes can take the form of tubes or pipes as required by architectural restrictions. Additionally, shop fabrication of steel shapes helps insure quality control. In this type of construction, in general, at each floor level heavy steel beam is framed to these composite columns. Often, these connections are required to develop shear yield and plastic moment capacity of the beam simultaneously. This paper summarizes results and recommendations from a pilot study conducted to develop a moment-resisting steel connection detail for connecting steel beams to composite columns of the type described above. The focus of this pilot study was on composite columns having a square or rectangular cross section.
