1. 当有抗火要求并且没有其它保护的情况下,型钢混凝土柱是有优势的。此外,在型钢混凝土柱的混凝土保护层中配置钢筋,可以很容易地增加它的强度。
Steel reinforced concrete columns have the advantage that they meet fire resistance requirements without any other protection. In addition, they can be easily strengthened by reinforcing bars in the concrete cover.
2. 组合梁包括型钢和起组合作用的一个或两个钢筋混凝土翼缘
Composite beams consist of a steel section acting compositely with one (or two) flanges of reinforced concrete.
3. 钢结构和组合结构工程常用于超高层建筑,大跨桥梁和大跨屋盖,这种结构体系具有较高强度自重比,在抵抗失稳和保证使用功能方面具有较大的抗弯刚度,是高效的结构体系。
Steel and composite construction is often adopted in super high-rise buildings, long span bridges and roof structures owing to high structural efficiency with large strength-to-self-weight ratios as well as large flexural rigidities against instability and serviceability problems.
