This paper reports a shaking table test of a half-scale two-storey brick masonry structure. The lower floor ceiling was shielded by a timbrel vault while the upper floor ceiling was covered with a slab composed of timber joists and panels. The specimen was scaled according to the Cauchy law. A code-based triaxial artificial accelerogram was incrementally applied up to 200% excitation. After the test, the walls showed severe damage induced by torsional and rotational behaviour. On the other hand, the timbrel vault showed limited damage. In this paper, attention is paid to digital image correlation (DIC) based 3D displacement measurement considered in the test. Digital technologies have shown remarkable progress in recent years and DIC draws the attraction of the academia and industry for its application in structural testing. Remarks from this study present the seismic performance of a vaulted two-storey building and the potential of DIC for the shaking table tests of masonry structures.

摘要

This paper reports a shaking table test of a half-scale two-storey brick masonry structure. The lower floor ceiling was shielded by a timbrel vault while the upper floor ceiling was covered with a slab composed of timber joists and panels. The specimen was scaled according to the Cauchy law. A code-based triaxial artificial accelerogram was incrementally applied up to 200% excitation. After the test, the walls showed severe damage induced by torsional and rotational behaviour. On the other hand, the timbrel vault showed limited damage. In this paper, attention is paid to digital image correlation (DIC) based 3D displacement measurement considered in the test. Digital technologies have shown remarkable progress in recent years and DIC draws the attraction of the academia and industry for its application in structural testing. Remarks from this study present the seismic performance of a vaulted two-storey building and the potential of DIC for the shaking table tests of masonry structures.
