Research Abstract

The main purpose of this project is to investigate both theoretically and experimentally, the strength of carbon fiber chip reinforced concrete shells with openings under partial load. Possibilities of stress disturbances influenced by the openings within shell surface and the partial load with various contact shapes onto shell surface could be hardly estimated in the evaluations for concrete shells. In this project the effect of opening within the shell surface on shell strength and cracking patterns was investigated. Furthermore the effect of partial loading patterns with a point and a line on shell strength and the nonlinear behavior was also investigated.
The experimental study was conducted on small-scale micro-concrete cylindrical shell specimens without or with openings. Two different types of reinforcing materials for concrete shells were adopted. The one was a steel bar as standard concrete shell reinforcement materials, and the other was a carbon fiber chip without steel bar r … More einforcing, which was mixed in concrete shells. The latter case was concrete with mixed-in carbon fiber chips, i.e.carbon fiber chip reinforced concrete, the features of which were higher homogeneity, isotropy and tensile strength than standard concrete reinforced with steel bars. Partial load was applied perpendicularly onto the shell surface until the final failure occurred.
The theoretical study was conducted using the nonlinear finite element analyses including concrete cracking and tension stiffening effects. In numerical analyses, three types of line load density patterns were adopted, which were uniformly, both-end-weighted, center-weighted types. The effect of line load density patterns on shell strength were investigated in evaluating the experimental results.
The ultimate strength and the nonlinear behaviors of carbon fiber chip reinforced concrete shells in comparison with standard steel reinforced concrete ones were discussed based on the results of the analyses and experiments. Less
