STRUCTURAL DAMAGES OF BEAMS IN MULTI-STORY RC SHEAR WALLS WITH MULTIPLE DOOR OPENINGS

摘要

This paper reports the test results of two 1/4 scale 3-story shear wall specimens subjected to cyclicloadings. One of the specimen had diagonally aligned openings and the other had vertically alignedopenings. The displacements of the beams around the openings were measured using digital cameras.The deformations obtained at the intermediate fl oors of the specimen with vertically aligned openings,which showed the most brittle behavior, were concentrated in the areas between the openings. Those ofthe specimen with diagonally aligned openings, with more ductile behavior, were widely distributed.
