  • From the viewpoint of fire-fighting activities, public building have structural and management problems in fire, so evacuation disturbance and risk of expanding combustion are high. As a result of analyzing various fire fragile factors of public building, The evaluation areas were derived from safety systems, fire-fighting facility, structure safety, general safety and the evaluation factors were presented. Also, the characteristics of domestic and foreign certification systems were analyzed by comparing and analyzing the status of fire safety performance certification system for 6 domestic and overseas apartment houses. In conclusion, the 5 convergence directions of certification system and 22 evaluation items by 4 evaluation fields were derived, and based on this, we have established 3 convergence introduction plans of fire safety performance certification system of public building.

  • The purpose of this paper is to suggest a method for applying a reasonable dam axial seismic load loading method and load-bearing capacity evaluation method in the dynamic analysis of the pier part of a concrete dam to which the seismic force of the collapse prevention level is applied. To this end, the pier part of a concrete dam was selected as a target facility, and the characteristics of the dynamic behavior in the axial direction of the weir dam were analyzed through dynamic analysis applying various weir widths, and 'U.S. The load-bearing capacity evaluation was performed by applying the RC hydraulic structure evaluation technique suggested by the Army Corps, 2007'. As a result of the study, when applying seismic force in the axial direction of the pier part, it is more realistic to assume that the axial direction of the weir part dam behaves as a rigid body and 'U.S. Army Corps, 2007' suggested that the method of reviewing the load-bearing capacity for moment and shear was considered reasonable, so it was concluded that improvement of the current evaluation method was necessary. If the improvement of the research result is applied, it will have the effect of deriving more reasonable evaluation results than the current seismic performance evaluation method using CLE. It is judged that additional research is needed in the future on the torsional moment occurring in the pier part.
