Advisor: Benjamin Dymond. 1 computer file (PDF); xxv, 324 pages.The web-shear capacity of hollow-core slabs both with and without concrete or grout core-fill material, as well as slabs that were cast with a solid extruded core (i.e., with one of the voids omitted), was experimentally investigated using two different hollow-core slab geometries to evaluate how the fill material affected the shear capacity. The shear demand at failure was compared to five different methods of predicting the shear capacity of hollow-core slabs: ACI 318 (2014), the AASHTO (2017) sectional design model, a method proposed by Lin Yang (1994), the EN 1168 (2011) general method, and the EN 1168 (2011) simplified method. Additionally, a web-shear capacity prediction method was proposed based on the ACI-ASCE Committee 326 (1962) report on shear and diagonal tension.enconcretecore-fillhollow-coreprestressedshearThesis or Dissertation
