The volume of construction waste material from the entire waste material volume in Korea is approximately 47.3% to take the biggest ratio, and from them, the waste concrete takes up approximately 62.8% that recycling is an urgent issue to address. Therefore, the government recommends more diverse and broader facilitation of the recycled aggregate in order to promote recycling the construction waste materials. In addition, when using concrete recycled aggregate in building, building standard such as floor area ratio and building height are being mitigation. The standard is a condition that mitigation the floor area ratio by up to 15% when using up to 25% of concrete recycled aggregate. Therefore, this study reviewed the relaxation of construction of construction standards when using concrete recycled aggregate in order to actively recommend the use of concrete recycled aggregate. And using the recycled coarse aggregate among the recycled aggregate, the appropriate mixing time in the batch plant according to the substitution rate was derived. In addition, using recycled aggregate admixture in order to improve the drying shrinkage, did comparative analysis about physical and mechanical property of concrete.

국토해양부는 지능형 건축물 인증제도의 활성화를 위하여 시행규칙과 고시를 각각 제정하고, 지난해 12월 1일 공포했다. 이 제정안은 2006년부터 지침으로 운영 중인 '지능형 건축물 인증제도'가 지난해 5월 건축법 개정으로 법적 근거가 마련되었고, 건축 기준 완화 인센티브가 확대됨에 따라 이번에 기존의 지능형 건축물 인증 세부시행 지침을 보완한 것이다. 이번 규칙 및 고시는 지능형 건축물 보급을 확대하기 위하여 업무시설 외에 공동주택, 판매시설, 문화 및 집회시설 등으로 인증대상을 확대하고, 원활한 인증제도 운영을 위한 인증기관 지정, 인증절차 및 인증등급의 세분화, 인센티브 적용 방법 등을 주요 내용으로 하고 있다.

산업통상자원부(장관 주형환)가 지난 6월 16일 '액화석유가스의 안전관리 및 사업법' 제45조, '도시가스사업법' 제17조4항의 상세기준 개정안을 승인 공고하고 가스계량기 설치장소 환기 양호 기준을 합리화했다. 이전에는 '사람이 거주하는 건축물 세대 밖(복도, 계단 등)의 경우 창문 등을 열어 환기를 할 수 있는 장소'로 규정했지만 이번 개정을 통해 '환기가 가능한 창문 등(개방 시 환기면적이 $100cm^2$ 이상에 한한다)이 설치된 장소'로 완화했다.

A sprinkler is a fire extinguishing equipment installed in a protected area where a detector or head detects a fire and automatically puts out the fire. However, the Ministry of Land, Infrastructure and Transport's "Regulations on Building Evacuation and Fire Protection Standards, etc." stipulate that fire compartment area should be reduced to three times by installing sprinkler facilities in the case of factories and warehouses. In this study, fire hazard was analyzed for a real PCB factory which mitigated the fire protection zone by sprinkler installation, and the head opening characteristics of sprinkler facilities through computer simulation, installation standards of sprinkler facilities, thermal performance, operating range, and the amount of water sprayed to identify the problems of operation of sprinkler facilities in case of fire, and to suggest the grounds such as required sprinkling flow rate for system improvement.

Purpose: This study aims to analyze design guidelines for hospice facilities in the US, UK, and Canada focused on design considerations and space requirements, and utilizes them as baseline data for establishing standards for Korean hospice facilities. Methods: Comparative review was carried out to investigate hospice care models, design consideration, and room sizes and requirements for design guideline of hospice facilities in United States, UK and Canada identified on electronic database and review articles, and to examine major characteristics and tendencies of hospice facilities. Results: The hospice care models characteristics in design guidelines is generally largely divided into hospital-based hospice facility, Nursing home-based hospice facility, and daycare hospice. The design considerations in hospice facilities focused on medical efficiency, flexibility, barrier-free environment, person-centered care, and stability. There is also a need for single resident room, rooms for the patient's family, and isolation room for infection control. Implications: it is recommended to establish standards for the installation and operation of required and recommended rooms and considerations when establishing the standards of hospice facilities in Korea. This Study is limited to a simple comparative analysis of the framework of guideline.

An evacuation simulation was carried out to confirm evacuation efficiency for stair width and problems in calculation of occupant load for high-rise buildings. The evacuation time and number of evacuated persons from a 39 story condominium-mercantile building were calculated by using Simulex for stair widths of 1.2 m, 1.5 m, and 1.8 m. The total occupant load based on the Korean code was higher than the number of actual residents by 2.3 times, and that based on the NFPA 101 Life Safety Code by 2.6 times, respectively. For the occupant load based on the Korean code, smaller stair width resulted in lower evacuation efficiencies due to bottlenecks in egress. For the actual residents and NFPA code-based occupant load, a high evacuation efficiency and negligible effects of the stair width on evacuation efficiency were confirmed. It was shown that there was a bottleneck even at the stair width of 1.8 m for the Korean code-based occupants, while the stair width of 1.2 m provided safe egress to the actual residents or NFPA code-based occupants. This recommended further studies on possibility of lowering the level of the Korean code in calculation of the occupant load.

In this study, an experimental study was conducted to analyze the hysteresis behavior according to the steel fiber aspect ratio and volume fraction of diagonally reinforced concrete coupling beams under to cyclic loading. The aspect ratio and volume fraction of the steel fibers were set as the main variables, and 4 specimens were fabricated in which the amount of transverse reinforcement of the coupling beam suggested in the domestic building structural standard was relaxed by about 53%. In the experiment, cyclic loading experiments were performed in the displacement control method in accordance with ACI 374.2R-13, and as a result of the experiment, it was found that all specimens containing steel fibers exceeded the nominal shear strength suggested by the current structural standards. As the aspect ratio of the steel fibers increased, the steel fibers prevented the buckling of the diagonal reinforcement, and the bridging effect of the steel fibers held the crack surface of the concrete. The shear strength, stiffness reduction and energy dissipation capacity of the specimens containing steel fibers were superior to those of the Vf0 specimens without steel fibers. Therefore, it is judged that the steel fiber reinforced concrete can relieve the details of the transverse reinforced.

This study in focused on proposing the improvement plans for refuge and fire-fighting facilities in large shopping malls that are radically spreading. The main subjects are as follows. - The refuge measure for large shopping malls - Problems of installing the refuge facilities in stores and the solutions - Problems of installing the incendiary facilities in stores and the solutions - Problems of installing the indoor fire plug in stores and the solutions As result of the study, it has turned out that escape stairs which are set up according to the standard of size in the process of design plan, have to be decided for their amount, position, specification, etc, in consideration of the number of residents. It is also required to tighten a standard of installing a sprinkler instead of lightening the fire-fighting section in stores, considering obstacles due to facilities installed and procurement of the escape path. In addition, it needs to lighten a standard of installing the indoor fire plug, which is voluntarily set up at the store section incase of installing a sprinkler to make a practical fire-fighting facility available.

The demand for promoting industrialization construction methods is increasing in Korea to cope with various construction environments, such as the lack of construction engineers, aging construction workers, and the government's 52-hour workweek policy. The industrial housing accreditation system was introduced in 1992 to recognize and improve the quality of industrial housing, but only six companies are currently certified, and there are no records of constructing industrial houses. Currently, the industrialized housing accreditation system in Korea comprises standards for the recognition, revocation of recognition, and promoting the construction of industrial houses. Therefore, this study analyzed the regulations of the industrialized housing accreditation system, derived the problems of each regulation, and derived improvement directions to promote the industrialized housing accreditation system in Korea. Specific measures include expanding the current industrial housing accreditation scope to quasi (semi)-housing, revising the performance and production standards of industrialized housing, relaxing the building standards, and providing financial support to promote industrialized housing.
