    • Abstract
  • Pointing to the longitudinal cracks of wide hollow slabs in the local press experiment, reasons of longitudinal cracks are analyzed. Then integrating the anchor end section design of wide hollow slabs, analytical models are presented and analytical method is derived for anti-crack analysis of the anchor end. Moreover, factors such as the dimensions of the anchor end section, eccentricity of prestressing in belly ban and anti-shear reinforcements in shear faces are analyzed. Thus the longitudinal anti-crack analysis program is developed. Finally, the wide hollow slab used in Suqian-Huaian highway is analyzed. The analytical results accords with the field local press experiment results reasonably.
