Abstract

This document presents the complete overview on the test results obtained in the 2019 experimental campaign on timber-masonry connections, in as-built and strengthened configurations. The tests have been performed in two phases, the first phase in spring 2019 and the second phase in summer 2019. The aim of this test campaign was to characterize the seismic response of joist-wall connections, therefore monotonic, cyclic and high-frequency dynamic tests were scheduled. In the present report, after a general introduction, a detailed overview on the adopted samples and on the testing methods will be presented, followed by discussion of test results and some general conclusions.
The conducted experimental campaign refers to common typologies of two as-built timber-masonry connections, with five proposed retrofitting solutions. The presence of the as-built tested connections and the field of application of the strengthened versions are quite wide: the percentage of unreinforced masonry buildings in the Groningen gas field area can be quantified as 77% of the existing building stock.
