The purpose of this study is to analyze the effect of the installation of evacuation safety zones in residential semi-high-rise apartments. To this end, it was analyzed by the pathfinder program that RSET(Required Safety Egress Time) was shortened up to 509.8 seconds when the number of people was gradually increased according to three scenarios as a virtual model for the 39-story apartment with an evacuation safety zone on the 17th floor. Optimizing evacuation routes and installing elevators have been shown to increase the efficiency of installing evacuation safety zones as variables that reduce RSET. By analyzing the safety of semi-high-rise apartments using evacuation safety zones, this study discussed the implications and suggestions of establishing an evacuation safety zone.

This study sought to suggest a structural design guide and to investigate the structural performances of the new beam-slab system in order to decrease the height of floors in high-rise steel structure apartments. Experiments were performed to assess the capacity of the new beam-slab system in a steel structure with 9.8-m span, particulary structural material test, pure bending test of composite beam, three-point bending test of composite beam, and bending and shearing tests. Results showed that the suggested composite beam had stable structural behavior when stud connectors were located in the upper flange, and upper bars were calculated normally according to the design of the slab.
