Abstract
Methods to evaluate the strength and deformation capacity of reinforced concrete walls with openings were studied using a wide range of experimental data. Firstly, a method to multiply the shear strength of a wall by a reduction factor due to opening proposed by AIJ in 2010 was examined. Next, a method adding up the strengths of columns with wing walls besides an opening was examined. In these examinations, the currently used empirical method and the theoretical method based on the truss-arch analogy were considered. Finally, an evaluation method for obtaining the deformation capacity by using an effective factor of concrete strength to calculate the shear strength based on the theoretical method was examined.
