Tube jack testing for irregular masonry walls: prototype development and testing
| Resumo: | This paper presents the development and initial testing of tube-jack prototypes for the enhanced non-destructive testing method called tube-jack testing. The tube-jack system is being developed to provide a less destructive method than traditional flat-jack testing for determination of mechanical characteristics and stress states in irregular masonry walls. PVC, rubber, and latex tube-jack prototypes were constructed and tested using various methods. Rubber and latex prototypes were improved with fabric socks added to the design. Final conclusions suggest further tube-jack prototype testing with the modified prototypes in larger masonry specimens and investigation into the effects of horizontal stresses induced by the pressurization. |
