摘要
钢—混凝土组合梁与传统的钢筋混凝土梁相比,具有跨度大、节省模板、减轻结构自重和较好的延性等优点,具有十分广阔的应用前景。系统总结了钢—混凝土组合梁抗弯性能(包括正弯矩作用下和负弯矩作用下)的研究现状,并指出了目前研究存在的问题与不足。
Steel-concrete composite beams have many advantages, which include being large in span length compared to conventional reinforced concrete structures, economical in construction formwork, light in their own weight, and good in ductility, as a result of which they can find wide applications. A systematic study and analysis are made of the flexural behavior of steel-concrete composite beams in the paper, including that under the sagging moment and that under the hogging moment, with problems and shortcomings existing in the present research pointed out.
