The fatalities of the evacuation facilities of the buildings accessed by unspecified people on the daily basis are significantly emerged as a problem. Evacuation facilities should be designed for common human behaviors the assumption that the customers are not familiar with the buildings. In addition, the characteristics of modern buildings such as high-rising and enlarging should be considered to design the evacuation plan. The evacuation is a problem that people reach a safe place with themselves. The architectural plan for the life safety should be established to minimize various disaster damages. To do so, the factors such as time, risks on the steps, combustion ash variables, safety training should be considered on the architectural planing.

High rising of the buildings offers a number of risk factors than ever before with regard to fire prevention. Especially in the construction site of high-rise buildings, people waste golden-time during the evacuation because temporary fire fighting facilities are not installed and transferred to a large fire because of fire suppression failure. In this study, the researcher derives the problems of fire protection in high-rise buildings construction sites and proposed the measures in such the legal aspects as fireᆞ building construction code and etc. There are the legal improvements such as orders of construction suspension in the problems of fire safety, appointing fire safety manager, temporary fire protection installation standards, enhancing penalty provisions regarding the use of fire, operating self fire brigade, confirming on-site after completing fire-protection facalities, establishment or strengthening special fire-protection investigations

Large enclosure means a space of high ceiling and large floor. Designing the heating system, many thermal conditions exist, such as thermal comfort, IAQ, heating load and energy efficiency etc. The prediction of the temperature distribution is carried out according to some of the diffuser angle. The simulation conditions are 7 m high diffuser, 4/2 inlet/outlet diffusers, 39 °C discharge air temperature, and 6 m/s exit velocity. The results show that 45° diffuser provides an optimal thermal environment, and the reason is that the temperature is closed to the designed temperature 22 °C at 1.18m elevation plane. As the diffuser angle is decreased, the temperature of the upper region is increased for the thermal buoyancy effect. And the asymmetry of the temperature distribution is increased.

Since the execution of structural design by professional structural engineers is not mandatory for small-size buildings in Korea, structural design is conducted by architects or contractors resulting in concern about the seismic safety of the buildings. Therefore, the Korean Structural Engineers Association proposed dedicated structural design criteria in 2012. The criteria were developed based on a deterministic approach in which the structural members are designed only with information of story and span length of the buildings and without structural analyses. However, due to the short time devoted to their development, these criteria miss satisfactory basis and do not deal with structural walls popularly used in Korea. Accordingly, the Ministry of Land, Infrastructure and Transport launched a research on the 'development of structural performance enhancement technologies for small-size buildings against earthquakes and climate changes'.. As part of this research, this paper intends to establish direction for the preparation of deterministic structural design guidelines for seismic safety of domestic small-size reinforced concrete buildings. To that goal, a typical plan of these buildings is selected considering frames only and frames plus walls, and then design is conducted by changing the number of stories and span length. Next, the seismic performance is analyzed by nonlinear static pushover analysis. The results show that the structural design guidelines should be developed by classifying frames only and frames plus walls. The size and reinforcement of structural elements should be provided in the middle level of the current Korean Building Code and criteria for small buildings by considering story and span length for buildings with frames only, and determined by considering the shape and location of walls and the story and span length as well for buildings with frames plus walls. It is recommended that the design of walls should be conducted by reducing the amount of walls along with symmetrically located walls.

We investigated the distribution of asbestos in Seoul for 16 school buildings built before and after 1990, includingkindergartens, elementary schools, middle schools and high schools. The risk assessment standards of AHERA,HSE and ASTM were reviewed and a comparative analysis of assessment standards was conducted in schoolbuildings. For the risk assessment of 16 schools, 170 samples were selected, each of which was assessed usingstandards of AHERA, HSE and ASTM. The school buildings included the ACM (asbestos containing materials)ranged 3-4% of chrysotile and 1-3% of amosite in classroom ceilings and has 7-8% chrysotile in partitions of studenttoilets. The airborne concentrations of fiber materials were ranged with 0.002-0.022 fiber/cc in school buildingsby PCM. In this study, a simplified rating scale was used three categories of Good, Damaged and SignificantlyDamaged. In the result of comparative analysis for the risk assessment criteria, it was found that 113 samples, 132samples and 82 samples were classified as Good when assessed by AHERA, HSE and ASTM, respectively; and46 samples, 29 samples and 53 samples as Damaged, respectively; and 12 samples, 8 samples and 34 samples asSignificantly Damaged, respectively. From the distribution of asbestos and the comparative analysis for the riskassessment criteria, the management plan and new risk assessment were made based on the Korea backgroundshould be established to control asbestos exposure to students from damaged ACM and will be revealed that theassessment for the current condition and potential for disturbance on asbestos in school buildings.

본 연구에서는 초고층 건물의 풍동실험에서 얻어진 풍하중에 대하여 모드에 기초한 풍응답 해석을 수행하여 사용성을 검토하고, 목표 응답수준을 획득할 수 있는 수동 및 능동 질량형 장치의 예비설계까지 수행 가능한 프로그램을 개발하였다. 본 연구에서 개발된 프로그램을 실제 초고층 건물의 풍동실험결과에 적용하여 TMD와 AMD의 설계를 수행하였으며, 가속도 응답과 질량체 이송거리를 중심으로 결과를 비교분석하였다. TMD와 AMD 모두 요구되는 응답 수준을 만족하는 최소의 질량체를 사용하는 경우 질량체 이송거리가 증가하는 문제점이 발생하였다. 특히 AMD는 TMD 보다 적은 질량체로도 사용성 기준을 만족하는 응답수준을 획득할 수 있다는 장점이 있었으나, 질량체의 이송거리가 지나치게 커지는 문제점이 있으며, 고주파통과필터와 같은 부가적인 이송거리 저감대책이 요구된다.

This paper deals with steel braced frame as increasing the lateral strength and ductility in order to seismic retrofit of existing buildings and discusses the designing criteria and calculation method of retrofitted buildings. The addition of steel braced frame can be effective for increasing the lateral strength and ductility of existing buildings. However, There is a problem in utilizing this method. It is the approach to provide an adequate connection between the existing RC frame and the installed steel braced frame, because global strength by failure mode(three type) depends on detail of connection and strength of existing RC frame. So, the designer must be confirmed if it satisfies the required performance or not. Failure mode of type I is the most appropriate for increasing the lateral strength and ductility. Seismic performance evaluation and strength calculation of seismic retrofit are performed by guideline by KISTEC(Korea Infrastructure Safety & Technology)’s “seismic performance evaluation and rehabilitation of existing buildings” and Japan Building Disaster Prevention Association. Buildings are modeled and non-linear pushover analysis are performed using MIDAS program.

This paper presents the seismic evaluation and prediction of a damaged piloti‐type Reinforced Concrete (RC) building before and after postretrofitting under successive earthquakes. For considering realistic successive earthquakes, the past records measured at the same station were combined. In this study, the damaged RC building due to the first earthquake was retrofitted with a buckling‐restrained brace (BRB) before the second earthquake occurred. Nonlinear Time History Analysis (NTHA) was performed under the scaled intensity of the successive ground motions. Based on the extensive structural response data obtained form from the NTHA, the fragility relationships between the ground shaking intensity and the probability of reaching a pre‐determined limit state was were derived. In addition, The the fragility curves of the pre‐damaged building without and with the BRBs were employed to evaluate the effect of the successive earthquakes and the post‐retrofit effect. Through the seismic assessment subjected to the successive records, it was observed that the seismic performance of the pre‐damaged building was significantly affected by the severity of the damage from the first earthquake damages and the hysteresis behavior of the retrofit element.

비정형 초고층 구조물은 골조 직교성이 해제되고, 형상이 복잡해 기존 설계방식보다 많은 문제점이 발생된다. 비정형성으로 인한 문제점은 설계안을 지속적으로 변경시켜 프로젝트의 효율성을 저하시킨다. 또한 해외프로젝트의 경우 해당업체 간혹은 해당국가 간 의견차로 국내보다 더욱 많은 변경상황이 발생되고 있다. 따라서 지속적인 변경상황에 전산플랫폼을 사용할 경우 효율적으로 설계변경업무에 대처할 수 있다. 파라메트릭 기반의 전산플랫폼인 StrAuto를 이용할 경우 최적의 구조 설계대안을 신속히 선정할 수 있다. 특히 StrAuto는 비선형 내진성능평가를 위한 해석 툴 간의 신속한 모델링 연동도 효율적으로 가능하다. 그래서 본 연구에서는 지진하중 변경에 따른 전산플랫폼을 이용한 내진성능평가 프로세스를 현재 구조설계가 진행 중인 몽골지역 최고층 빌딩 프로젝트에 적용하고 검증하려 한다.
