The tradi - tional pre - stressed reinforced concrete hollow slab has not met the needs of the con - struction market , which leads to the shrink of the prefabricate part industry , in order to prosper the prefabricate part industry in our country and make the best of the advan - tages of pre - stressed reinforced concrete hollow slab , we should use the high effective pre - stressed reinforced concrete hollow slab made of high strength material , for the reason that it not only inherits the advantages of the traditional pre - stressed reinforced concrete slab , but also meet the needs of big - span , large - load modern buildings , has better ductility and crack control property , lower cost and more competitive in the mar - ket 传统的预应力空心板已经不能满足建筑市场的要求，也导致我国的预制构件行业的萎缩，为了振兴我国预制构件行业，充分挖掘预应力空心板的优点，利用高强材料生产的高效预应力空心板不仅具有传统的预制板的优点，且能够较好地满足大跨度、大荷载的现代建筑的要求，其延性及裂缝控制性能均优于传统的预应力空心板，而且生产成本降低，具有很强的市场竞争能力。
The experimental study of twelve push - out specimens with different hole molds and different materials filled in holes and two composite steel - fdpcp ( full - depth precast concrete panels ) beams of a full shear connection and different hole mold , as well as a composite steel - fdpcp beams of a partial shear connection and square holes was conducted in this paper , the authors gain following results : three composite steel - fdpcp beams all have good composite action and perfect work behaviors as a whole and the composite steel - fdpcp beams is a new - style structure which should get further research and development 摘要对12个不同预留孔形、孔内不同填充材料的推出试件及2根不同预留孔形的完全剪力连接与1根部分剪力连接的钢混凝土预制板组合梁进行了试验，结果表明，只要预留孔形设计合理，灌孔混凝土强度得当，钢混凝土预制板组合梁就具有良好的组合效应和整体工作性能，是一种有发展前途和广泛应用领域的新型组合结构。
