摘要：
The authors propose a method for quantifying concrete cracks by means of crack area as the product of the crack width and crack length to evaluate the shielding performance of reinforced concrete walls. Cyclic loading tests on reinforced concrete shear wall specimens were performed, and the crack widths of the walls were measured in detail. The test results show that the crack area correlates with the drift angle of the wall. Furthermore, two methods for calculating the crack area through nonlinear finite element analysis are proposed. The calculated crack areas correspond well to those of the test specimens. © 2021 Architectural Institute of Japan. All rights reserved.
