The purpose of this study is to analyze the effect of the presence of Masonry Wing-walls on the performance of adjacent columns and structures when an earthquake occurs. Shear failure of the columns of Heunghae Elementary School was observed patently in November 2017 in the Pohang earthquake. The shear damage patten of the columns seemed very closely related to the existence of the Masonry wing-wall. In general, in structural design, Masonry infill-walls in the framework are assumed as only loads and not reflected to structural modeling. However, seismic damage cases and existing experimental studies show that Masonry Wing-Walls affect structural behaviors and damage pattern. There are many prior studies and examples of Masonry infill-wall and
Masonry partial-high wall. However, the contribution of the Masonry wing-wall has been discussed since the earthquake in Pohang, but the existing research cases and references have not focused on it is structural roles. In order to understand the effect of Masonry wing-walls on the performance of a structure, in this study, four types of modeling such as two types of Masonry wing-walls, Masonry partial-high walls, and bare frame were studied. The strength and stiffness of the materials are referred to existing research and literature. Equivalent struts for nonlinear static analysis were applied as the structural analysis method of the Masonry wing-wall. Analysis results showed that Masonry wing-wall increases and decreases shear force on adjacent columns during earthquakes. Thus, it was found that the Masonry wing-wall was related to the shear failure of the column, which was the main cause of the building''s damage during the earthquake.
