Shake table test of RC walls' coupling provided by slabs

When designed to the seismic load effects, reinforced concrete walls connected by slabs without coupling beams are usually considered cantilever walls. Several recent studies indicated that themselves could provide strong in some cases, and respond differently from To study slab-to-wall piers interaction, a shake table test of half-scale three-story specimen was conducted within HORIZON 2020 SERA-TA project. The consisted four rectangular linked three slabs. It subjected series excitations increasing intensity. In last tests, nonlinear response wall observed. At excitations, one pier tensile, while adjacent compression forces. crack pattern asymmetric different cross-shaped damage pattern, typical for provided considerably stronger than it expected. share overturning moment resisted frame action induced more 50%. All were fully activated significantly damaged. Their primarily flexural. effective width equal their total width.
