| 摘要 |
A load bearing structural member such as a wall, floor or roof panel, comprising a core of low density particulate material in a cementitious matrix, sandwiched between thin outer skins of a steel fibre reinforced cementitious material on at least two opposing faces of the core. One or more post-tensioned tendons extend between opposed ends of the structural member. These posttensioned tendons are positioned within the structural member between the opposing faces thereof to distribute post-tensioning stresses substantially evenly throughout the outer skin. |
