| Abstract: | This paper introduces a set of model experimental result about hole structure, analyses and studies the act the part of use SFRC reinforce high stress area. The paper researches the feature bearing force and failure pattern for hole structure under uniformly distributed load condition. This paper analyses the strain distribution and crack propagation and variation law of the hole structure under diffrent SFRC thinckness condifion. The paper gives a series of result of the model experiment. It can be used as a reference for engineering design. |
