The dataset contains the predominantly excel spreadsheets for the dynamic and static loading of fibrous plaster ceilings. The dataset cover the in-situ monitoring of accelerations in a historic partner theatre, termed Theatre 'A' and the monitoring of accelerations, displacement and strain of laboratory large scale fibrous plaster ceiling panels, small scale sample tests include flexural, compressive and tensile tests. Tensile tests featured newly manufactured and historic material, with the newly manufactured specimens featuring both traditional materials and modern alternative repair material options. Tensile tests on wads were conducted at both the Diamond Light Source and in the structures laboratory. The compressive tests feature historic material.
