Cyclic test of three-storey masonry-infilled RC frame

Node Image

Within the HERAKLEITOS project a 3-storey masonry-infilled frame was tested under cyclic loading.

The 2/3-scale specimen serves as a Control specimen. A twin one will be strengthened with Textile-Reinforced Mortar and will be tested under the same loading conditions.

Key characteristic of the specimen behavior was the damage concentration on the 1st floor, in detail diagonal cracking of the masonry infill panel, which initiated at the early stage of loading with the simultaneous formation of struts on both loading directions, and shear failure of the right column just below the joint.

The Base Shear versus Top Floor Displacement curve synchronized with video frames from network cameras is presented in the high-speed video.
