Study on Stress and Deformation Performances of the Spliced Cement Formwork Reinforced by FRP
For permanent cement-base formwork, due to stay-in-place with concrete during all the service life and minor size of the end surface, the splicing methods of traditional formworks are not adapted to be used. In allusion to natures of the cement-base formwork, this paper presents ten types of splicing methods. For each method, a group of specimens are prepared and whose capacity and deformation performance are investigated. And meanwhile, stress and deformability of the full specimens without joint are researched under the same conditions. Through above splicing experiments, some reliable splicing method is obtained. The experimental results provided by this paper present a gist for investigation and application of the permanent cement-base formwork.
