［摘要］鋼肋預(yù)應(yīng)力混凝土疊合板（PCCSSR）是一種新型的疊合樓板，由預(yù)制混凝土底板、鋼腹板和混凝土上翼緣組成，具有抗彎剛度大、承載力和生產(chǎn)效率高的特點?；赑CCSSR的抗彎試驗，對PCCSSR在彈性階段的抗彎性能進行了數(shù)值模擬分析，并得到了PCCSSR的開裂荷載和荷載-跨中撓度曲線。結(jié)果表明，PCCSSR在施工期間具有足夠的抗彎承載力和剛度，滿足規(guī)范的要求；增加混凝土上翼緣的厚度可以明顯提高PCCSSR的抗彎性能，合理的鋼腹板開孔尺寸及間距和混凝土上翼緣局部削弱深度對PCCSSR的抗彎性能影響不大。同時，采用MATLAB得到了PCCSSR最為經(jīng)濟且力學(xué)性能優(yōu)異的截面形式。對PCCSSR的制作、安裝中存在的問題進行了分析，并給出了相應(yīng)的解決方案。

Abstract:Prestressed concrete composite slab with steel ribs(PCCSSR) is a new type of composite slab, which has the characteristics of large bending stiffness, high bearing capacity and high production efficiency. PCCSSR is composed of prestressed concrete bottom plate, steel web and concrete upper flange. Based on the bending test of PCCSSR, the flexural performance of PCCSSR in elastic stage was numerically simulated, and the cracking load and load-mid-span deflection curve of PCCSSR were obtained. The results show that PCCSSR has sufficient flexural capacity and stiffness during construction to meet the requirements of specifications; increasing the thickness of concrete upper flange can significantly improve the flexural performance of PCCSSR, and reasonable opening size and spacing of steel webs and local weakening depth of concrete upper flange have little effect on the flexural performance of PCCSSR. At the same time, the section form of PCCSSR which is the most economical and has excellent mechanical properties was obtained by using the MATLAB. The problems in the manufacture and installation of PCCSSR were analyzed, and the corresponding solutions were given.
