  • Currently, the number of a shopping center building is increasing because most people want to go a shopping center building easily for buying many things and eating some foods. That are a normal trend these days. However, the increasing number of shopping center buildings has been increasing the number of shopping center building fires which also have been making social problems. Therefore, this study was conducted for the fire department connection among other fire facilities because it is important for fire suppression. The research subject is on the fire department connections that are on 70 shopping center buildings of more than 5 years old constructed. Survey and analysis were conducted for 70 fire department connections. The result of this study is that all installed fire department connections have a type that includes one or two holes each at 65mm wide, and the average distance between fire department connections and access roads is 4.85m. The total average percentage of insufficiency conditions such as drive ways for fire trucks, visibility, accessibility, pressure range sign, installed height, cover of the hole, etc. is 45.3%. So improvement of law and systems, that are fire facility construction and maintenance implementations, will be needed in my opinion.

  • In this paper shows the development of the Program(FDS2EXODUS) for Generating Hazard condition file of BuildingEXODUS code based on the FDS Fire-simulation Data. The program were applied with numerical method to translate from FDS to BuildingEXODUS. Using both single or multi block meshes of FDS get to be possible. For application of fire effect, the fire data were loaded directly to BuildingEXODUS in the case of FDS code with using this Program(FDS2EXODUS). It was very convenient to input to BuildingEXODUS and could be reduced the procedure of egress simulation from fire disaster.

  • In the building, the opening penetrates the wall and serves as a spreading channel for smoke and flame in case of fire. In Korea, more than 1,500 fire plume are generated annually, and the number has increased by about 30% over the past five years. Therefore, in the case of windows protecting the opening, fire protection performance is important to prevent the spread of fire. However, in Korea, the standard for window is not clear. In this study, fire tests (EN 13823) for windows were conducted in Korea, and then fire protection performance of windows was compared. As a result of the experiment, PVC windows showed a phenomenon that they could not withstand the temperature during the fire experiment, and AL windows showed a difference in the degree of cracking of the glass.

  • The post - fire investigation is conducted on a fire-affected reinforced concrete shear wall building to ascertain the level of its strength degradation due to the fire incident. Fire incident took place in a three-storey building made of reinforced concrete shear wall and roof with operating floors made of steel beams and chequered plates. The usage of the building is to handle explosives. Elevated temperature during the fire is estimated to be $350^{\circ}C$ based on visual inspection. Destructive (core extraction) and non-destructive (rebound hammer and ultrasonic pulse velocity) tests are conducted to evaluate the concrete strength. X-ray diffraction (XRD) and Field Emission Scanning Electron Microscopy (FESEM) are used for analyzing micro structural changes of the concrete due to fire. Tests are conducted for concrete walls and roof slab on both burnt and unburnt locations. The analysis of test results reveals no significant degradation of the building after the fire which signifies that the structure can be used with full expectancy of performance for the remaining service life. This document can be used as a reference for future forensic investigations of similar fire affected concrete structures.

  • This study is intended to present a computational thermal model for a residential building. As the Performance Based Design is more popular, fire-intensity and fire-load have turned out to be very important factors for building design and can be predicted through some computational work. To predict and estimate the fire properties of a residential fire, we made some numerical models of combustibles and residential building. In a bid to validate the estimate values, computational analysis results from numerical models were compared with real fire tests. For computational analysis, the Fire Dynamics Simulator (FDS) was used with Large Eddy Simulation (LES) model for turbulence. Consequently, fire-intensity was well predicted and flash-over of rooms were successfully estimated.

  • Korean city had been rapid developed through high industrialization and rapid economic growth after the 1970's. The city development process was guaranteed the fulfillment of city function through the city expansion based on New Towns and satellite cities rather than the reformation of existing city. This city expansion caused by degrading of city, being backward and producing many problems. To solve this problems, it was considered the rehabilitation of retarded function with rejuvenation such as a special law accelerating urban renaissance and reorganization project. Also a fire protection performance did not satisfied the required conditions of modern FPP system, such as the function deterioration of building facilities, the technological development with FPP facilities, changed fire laws and building occupancy for social needs. Insufficiency of requirements depreciated the building value and intimidated a safety of residents. To solve this problem, the improvement of FPP was essentially required and also strongly recommended an analysis and a comparative study between the required FPP of existing building and it improving effective FPP. Therefore, purpose of this study is that establish the basic data to construct a system to analyze and compare the building FPP.

  • Because National Fire Safety Codes is mixed performance criteria and specification, and it defines the fire extinguish equipment type and standards that need to be installed in a building as one method. Therefore, to fully reflect the fire risk characteristics of the building, such as the wooden building there is a limit. In this study, suggested to the performance criteria drawn methodologies through fire load of wooden buildings studies, theory on performance and performance analysis to fire extinguish equipment of the wooden buildings is installed according to current fire safety codes.

  • Smoke and fire spread throughout the building as a result of problems in the fire prevention section of Uijeongbu Apartment Fire in 2015 and Jecheon Sports Center Fire in 2017 in Korea, causing a number of casualties. It is believed that the fire compartment standards need to be reviewed as the fire in recent buildings continues to show problems. In this study, a comparative analysis was conducted on the fire prevention zone standard with Japan to improve the fire compartmente standard in Korea.
