국내 재래시장 상가건축물은 타 상업지역 보다 노후화된 상업건축물이 상대적으로 많으며 밀집도 또한 높다고 할 수 있어 화재발생 시 화재확산 속도가 빠르고 화재진압이 어려워 인명 및 재산 피해의 가능성이 크다고 할 수 있다. 이에 따라 정부에서는 재래시장을 특정관리대상으로 지정하여 정기적으로 점검을 하고 있으나 소방시설에 비해 상대적으로 피난계획 및 피난설비에 대해서는 적절한 성능평가 및 점검이 이루어지고 있지 않고 있다. 이에 따라 본 연구에서는 대구시 소재의 특정관리대상으로 지정된 재래시장 상가건축물을 조사하여 재래시장의 평면유형분류를 하였고, 각 유형이 가지는 특성을 분석하였으며 대상건축물 피난설비의 실태조사를 통해 경년변화에 따른 설비의 노후화 특성을 분석하였다.

Recently, the need for new approaches and recognition of safety and maintenance has been raised for small vulnerable facilities in Korea due to the acceleration of aging facilities, various safety accidents, and increased frequency of use. In particular, small vulnerable facilities(SVF), including most social welfare facilities, are facilities used by many of the vulnerable groups, and safety management is very important. Therefore, this study investigated various statuses based on safety inspection results (31,114 cases) conducted over the past 13 years (2008-2020) for small vulnerable facilities in Korea, and evaluated the characteristics of each field and safety and maintenance performance level. This aims to present policy directions for strengthening safety management of facilities for the vulnerable by using basic data such as improvement of safety standards and maintenance strategies for small vulnerable facilities in Korea in the future.

건축물의 다양한 설비는 내부 거주자의 안전, 쾌적, 위생 등 환경적 요구를 충족시켜주는 기능을 수행한다. 소방용 설비의 경우 화재발생시 인명과 재산피해를 최소화하기 위한 중요한 기능을 담당하며 평상시 자주 사용되지는 않지만 화재와 같은 사고 발생시엔 확실한 작동이 요구된다. 소방용 설비는 경년변화로 인한 기기의 성능저하 및 고장발생의 우려가 큼에도 그 특성으로 인해 고장 및 기기의 결함을 조기 발견하는 것이 어렵다. 이에 국내에서는 소방설비에 대한 점검 기준을 마련하여 이를 소방용 설비의 유지보수를 수행하고 있으나 형식적인 점검방법으로 인해 다음 점검주기까지의 성능보장이 불가능하다는 한계점을 가진다. 이러한 문제점을 개선하기 위해서는 공학적 근거에 의한 소방설비의 내구연한을 제시될 필요가 있어 국내에서도 현재까지 소방설비에 내구연한 산정에 관한 논의가 활발히 진행 중에 있으나 내구연한 산정방법과 기준에 대한 연구는 미비한 실정이다. 본 연구에서는 일본 공업회의 자주적인 대처로 산정된 소방용설비용 내구연한 사례를 분석 고찰하여 국내 소방설비 기기의 내구연한 및 교체시기 산정에 대한 기초연구를 진행하였다.

The recent earthquake of Pohang (M5.4) and the Gyeongju earthquake (M5.8) suggested the possibility of a strong earthquake in Korea and reminded us that the Korea is no longer an earthquake-safe zone. In the disaster recovery stage in a disaster like an earthquake, the investigation of the damage situation and the safety assessment of the building serve to provide important information for the initial action such as establishment of the recovery strategy and rescue of the survivor. However, the research that depends on manpower can not cope with the difficulty of processing a large number of doses in a short time, and the expertise of the manpower must be taken into consideration, which may result in delayed initial action. In this study, we propose an rapid safety evaluation technique of building using unmanned aerial vehicle which evaluates the performance and safety of buildings by integrating conventional safety inspection method with unmanned aerial vehicle technology and developed evaluation method of each evaluation factor. In order to verify this, the buildings damaged by the earthquake in Pohang were checked and compared using this system. The results are consistent with the results of the existing emergency earthquake risk assessment. As a result, the possibility of checking the emergency safety using the unmanned aerial vehicle for the damaged structures in case of a large-scale disaster such as an earthquake was confirmed.

Due to the aging of a building, 38.8% (about 2.82 million buildings) of the total buildings are old for more than 30 years after completion and are located in a blind spot for an inspection, except for buildings subject to regular legal inspection (about 3%). Such existing buildings require users to self-inspect themselves and make efforts to take preemptive risks. The scope of this study was defined as the general public's visual self-inspection of buildings and was limited to structural members that affect the structural stability of old buildings. This study categorized possible damage to reinforced concrete to check the structural safety of buildings and proposed a checklist to prevent the damage. A damage assessment methodology was presented during the inspection, and a self-inspection scenario was tested through a chatbot connection. It is believed that it can increase the accessibility and convenience of non-experts and induce equalized results when performing inspections, according to the chatbot guide.

Although various efforts have been made every year to reduce electric fire accidents such as accident analysis and inspection for electric fire accidents, there is no effective countermeasure due to lack of effective decision support system and existing cumulative data utilization method. The purpose of this study is to develop an algorithm for predicting electric fire based on data such as electric safety inspection data, electric fire accident information, building information, and weather information. Through the pre-processing of collected data for each institution such as Korea Electrical Safety Corporation, Meteorological Administration, Ministry of Land, Infrastructure, and Transport, Fire Defense Headquarters, convergence, analysis, modeling, and verification process, we derive the factors influencing electric fire and develop prediction models. The results showed insulation resistance value, humidity, wind speed, building deterioration(aging), floor space ratio, building coverage ratio and building use. The accuracy of prediction model using random forest algorithm was 74.7%.

Recently, many accidents occur frequently because sprinklers aren't installed or don't work right when there are outbreak of fire in houses and aggregate buildings. Therefore, they can result in damage for humans and loss of property. Sprinklers are the most appropriate which can extinguish buildings' fire in the initial stages. Through lack of legal system, in domestic cases, sprinklers cannot operate their inherent performance. Domestic standard simply classifies installation objects according to types of business and forms of buildings, also divides into uses and floors of buildings. Especially it only regulates that sprinklers must be installed every floors in particular fire buildings that have more than eleven floors. While it doesn't need to install sprinklers below ten floors, so we are threatened the safety. In this study, we derived causes and implications by analyzing concepts of sprinklers facilities, installation standards in domestic and foreign legal system, and recent cases that expanded damages in fire accidents because of weak point of installation and control standards. In domestic cases, as a result, government has to provide an institutional strategy and law that regulate duty to install sprinklers to all aggregate buildings regardless of floors in terms of new buildings. Also, if someone who has existing buildings wanted to install them, government would guarantee subsidy to encourage installation. In addition, government supervises fire-fighting activities when there are fire by compensating standards about regular inspection by a qualified technician, operation and maintenance of sprinklers as well as reinforcement of administrative criteria.

Although most domestic concrete structures are simultaneously exposed to freeze-thaw and chloride environments, concrete durability in the field is evaluated by each single action, and the evaluation of chloride-caused damage of concrete requires additional indoor experimental analysis of chloride contents by coring samples from structures in the field. However, in Korea, policies to strengthen facility maintenance, such as 「Special Act on the Safety Control and Maintenance of Establishments」 and 「Framework Act on Sustainable Infrastructure Management」, have been established and implemented since 2018 and facilities subject to safety inspection management by the government and local governments increases, the effective simplification technology for the inspection and diagnosis of concrete structure is needed. Therefore, this study attempted to evaluate the possibility of determining the acceleration chloride penetration of freeze-thaw damaged concrete by using the surface rebound value. For this purpose, concrete specimens already having freeze-thaw damage by exposure to the freeze-thaw acceleration environment were immersed in chloride water. After that, the acceleration relationship of chloride penetration according to freeze-thaw damage was analyzed using the amount of chloride contents in concrete.
