Characterization of mortar-timber and timber-timber cyclic friction in timber floor connections of masonry buildings (dataset)

The seismic performance of buildings depends critically on the stiffness and strength of<br> storey diaphragms. Whilst for modern reinforced concrete or steel structures the<br> connection between floors and lateral resisting members is often assumed as<br> monolithic, timber floors and ceilings in masonry buildings are susceptible to sliding in<br> their supports. In fact, the anchorage of timber beams in masonry walls and<br> intermediate supports relies partly or totally on a frictional type of resisting mechanism.<br> The present work contributes to characterize this behaviour by presenting the results of<br> an extensive experimental programme with cyclic friction triplet tests between mortar<br> and timber units, and between timber and timber units. These were produced to be<br> representative of connection typologies characteristic of pre-modern and contemporary<br> construction periods. Each test was performed under a constant level of contact<br> pressure, which was increased throughout each series to cover a range of normal<br> forces foreseeable in building connections. Other aspects are also discussed, such as<br> the influence of cumulative loading or velocity. The experimental dataset is herein made<br> available for public use.
