本文描述了高温下具有圆形和细长腹板开口的全尺寸复合楼板蜂窝钢梁的性能的实验和数值研究。共有三个试件，包括三种不同的钢几何形状和加载条件，在高温下进行了测试。建立了材料非线性和几何非线性的有限元模型，并与实验结果进行了比较。本文还通过与数值模拟、试验测试和钢结构研究所（SCI）现有设计软件的比较，论证了所开发的简单设计方法的能力。
This paper describes an experimental and numerical study at elevated temperatures on the behaviour of full scale composite floor cellular steel beams with circular and elongated web openings. A total of three specimens, comprising three different steel geometries and loading conditions were tested at elevated temperatures. Finite element models were established with both material and geometrical non-linearity to compare with the experimental results. This paper also demonstrates the capability of a developed simple design approach in comparison with numerical modelling, experimental tests and existing design software used by the Steel Construction Institute (SCI).
