摘　　要：本文针对福建会堂工程设计实例，介绍了35米跨预应力钢与混凝土组合箱梁的结构设计，同时也简要介绍了其模型试验等情况。实践表明，对大跨度、重载荷之钢与混凝土组合梁施加预应力，是提高其承载能力、刚度、改善其受力性能和降低钢材消耗的有效方法。Based ou the sample of FUJIAN HALL project, the structural design of 35m span prestressed composite steel - concrete girders is introduced in this paper. At the some time, such subjects as its model examination ete are briefly discussed. The practice shows that composite steel -concrete girdere with long span, over loading are prestressed is to improve its load-carrying capacity, stiffness, mechanical behaviors and to reduce the cost of steel section
