historical centre of Lisbon taking advantage of the flat-jack method. These in situ tests aimed the evaluation of the rubble stone masonry deformability properties in compression (double flat-jack test) and the shear strength parameters (shear flat-jack test). This study was developed within the scope of the Portuguese research project

contact surface between the flat-jack and the cut (paper stamp). DOUBLE FLAT-JACK TEST The double flat-jack test supports the assessment of the masonry deformability properties in compression. The test procedure is described in ASTM C 1197-04 (2004) and in RILEM MDT.D.5 (2004). In this test two horizontal cuts, 40.0 cm spaced, were made in the wall

Comparison between plate jacking and large flat jack test

double flat-jack. Among the three types of in-situ tests, the flat-jack test is certainly the most attractive since it can be used to define the local value of the compression and also to study ...

Numerical Modeling of Single Tube-Jack and Flat-Jack Tests

Consequently, the in-situ test is equivalent to a compression test performed on specimens with different sizes, as shown in Figure 8. The tests were performed in keeping. Figure 7. Schemes of the double flat-jack tests performed on different wall sizes. Figure 8. Equivalent masonry prisms tested in compression by means of double flat-jacks.

Single Flat Jack Transfusion flat jacks are specially designed in-house, and manufactured by Hydra-Capsule, they have the ability to transfuse grout whilst under load, from a temporary to a permanent load. The design of the flat jacks allows for a balanced load and movement displacement throughout the grout transfusion operation.

The manual pump is provided with a manometer to monitor flat jack’s oil pressure during the test. A special automatic monitoring kit is available in order to connect a pressure transducer to the flat jack: this solution permit the connection of the flat jack to a datalogger for automatic data acquisition and alerting.
