In a case of fire at high-rise building or complex usage building, many evacuees uses staircase at once. At the staircase, confluence is happened between the evacuees from upper floors and ones entering to the staircase. The condition of merging may have impact on escape time, not only on the fire floor but also the time in the whole building. However there is less research about the condition of merging about staircase. The purpose of this study was to investigate the effects of merges in stair case and easiness of merging in various cases. The tests were conducted to compare different cases in: 1) crowd density, 2) directions of merges, 3) door open or close. The results lead to the following conclusions: 1) it is easier to merge at lower density; 2) it is easier to merge if the direction of the merging crowd is same as the direction of the crowd in staircase; 3) it is easier to merge if the door is open, and it lowers the evacuation flow rate by 70% at the door when the door is closed at start.
