[提要]  近年来钢-混凝土组合梁以其施工速度快、材料性能应用充分等特点在我国工程建设中得到了广泛的应用。跨度为35 m的T形钢-混凝土叠合板组合梁在清华科技园连体工程中得到了应用。与钢骨混凝土梁方案进行了比较，钢-混凝土叠合板组合梁比钢骨混凝土梁方案更加优越，非常适用于大跨横向承重结构。

Steel-concrete composite beams have been widely used in building and bridge engineering inChina. One practical example is introduced about the T type steel-concrete composite beams used as the long-span beams of 35m in Tsinghua Science and Technology Building in Zhuhai. The comparison is made between the current T type steel-concrete composite beams and the original SRC beams. The results show that steel-concrete composite beams have a great advantage over SRC beams in long-span flexural elements.
