摘要
进行了一榀钢-混凝土组合桥面板的足尺试验,剪力连接件采用PBL。在经典板理论的基础上,开展了组合桥面板的理论分析研究。探讨了荷载的傅里叶级数展开形式,得到了组合板变形的单傅里叶级数解法。结合试验结果,考察了组合板钢与混凝土之间的部分粘结性能,并引入修正后的折减系数。最后计算了钢-混凝土组合桥面板的挠度变化情况,并与试验值进行了比较,两者吻合良好。
A full scale test of steel-concrete composite slab has been studied in this paper,which use the PBL as shear connectors. 13ased on the theories of slab ,the theory analysis has been deyeloped. The loads are outspreaded in terms of Fourier series ,and the deflection of the slab was calculated by single formulation of Fourier series. Then, the partial bond performance between the steel and concrete was also studied according to the test results, and a modify ratio of the reduced rigidity was inducted. At last, the deformations of the steel concrete composite slab are calculated and compared with the test results ,the predicted values are in good agreement with experimental results.
