Seismic Performance of RC Shear Walls with Multi-Openings

Abstract eng:
This paper outlines a static loading test of RC shear walls with openings carried out to investigate the influence of different number and layout of the openings. All specimens have the same equivalent perimeter ratio of openings, that is 0.4. The test results showed that the shear strength, failure mode and deformability of RC shear walls with openings were significantly affected by the difference of the number and layout of openings. It was also observed that the overturning moment at the bottom of the shear walls with openings were smaller than those of without opening because the rotation at the bottom of the shear walls with openings became smaller due to the existence of the openings. FEM analysis was also conducted to simulate the hysteresis loops and failure progress of the shear walls with openings, and good agreement between experimental and analytical results was obtained.
