Recently, the abnormal weather due to global warming has led to increased frequency of typhoon and gale. Protruding Signboard is the most common type of outdoor advertisement in Korea which often causes falling accident due to strong wind, and led to serious damages on pedestrians or parked cars. However, there is no installation and structure standard for the sign board. Thus, this study conducted a wind tunnel experiment to analyze the influence of wind pressure coefficient distribution in accordance with the changes in experiment angles and separation distance of the protruding Signboard to wind pressure coefficient. There was difference in coefficient in accordance with the size of protruding Signboard, but there was no difference in coefficient in accordance with the separation distance between the sign board and building. The size of protruding Signboard was confirmed to be more influential to wind pressure coefficient than the separation distance.
