Abstract

Composite construction in steel and concrete represents a very effi cient structural solution because the materials are used according to their best properties. Concrete has good compressive strength and is easy to form into any shape, making it particularly suitable for fl at structures such as slabs. Structural steel has both high compressive and tensile strength together with high ductility. For conventional composite sections with a double symmetrical steel section and a concrete fl ange with a large eff ective width arranged above the steel top fl ange, usually fully plastic resistance is reached when the cross-section is classifi ed into cross-section Classes 1 or 2. This classifi cation avoids too slender cross-sections and prevents the risk of local buckling so that the cross-sections meet the requirements for high rotational capacity.

复合结构中的钢纤维混凝土作为增加阻力和延性的手段

钢和混凝土的组合结构是一种非常有效的结构解决方案，因为材料是根据其最佳性能使用的。混凝土具有良好的抗压强度，易于形成任何形状，特别适用于楼板等结构。结构钢具有高的抗压强度和抗拉强度以及高的延展性。对于具有双重对称型钢和布置在钢顶部区域上方的有效宽度较大的混凝土区域的传统组合型钢，当将横截面划分为1或2类横截面时，通常会达到完全塑性阻力。这种分类避免了过细的横截面，并防止了局部屈曲的风险，从而使横截面满足高旋转能力的要求。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
