Paratec - Practical Testing: Tyne-Tees University


Dynamic full-scale parapet wall tests were undertaken in the heavy structures laboratory at Tyne-Tees University. The tests clearly demonstrate the robustness of parapet walls reinforced with Cintec masonry anchors. The walls were impact loaded using a falling weight test rig designed to generate the force/tme history of an actual vehicle impact test that had previously been recorded and analysed at MIRA.
In this test, the Cintec reinforcement used was a 19.5 metre high yield MS multibar anchor comprising six individual stainless steel bars of 8mm in diameter. This was installed 370mm below the top of the wall. Raking anchors were also installed in pairs at 30° to the vertical. These were 100x3 x8mm diameter multibar anchors encapsulated in a 40mm diameter sock and installed in a 50mm diameter hole.	Although the bridge was shunted by the force of the impact, it remained intact with no significant spalling. The picture above shows the wall face opposite to the point of impact after two consecutive tests.
