  • In the case of korea, it was enforced the performance based design in 2011 for fire safety to the construction that is hard to safety secure by code based design. However as a result of domestic performance design case analysis, as it conducts that the standard is insufficient, most of cases show that they use the method of adding facilities by strengthening legal standards. Therefore on this study, it conducts the analysis of Performance based design seminar data that it was done by SFPE and each countries Performance based design guidelines. Also based on this, it will use the basic data for developing the domestic performance based design guideline.

  • Performance based design(PBD) is the method to make a fire safety design against them after predicting the factors of fire risk in a building. Therefore, predicting fire risk in a building is very important process in PBD. For predicting fire risk of a building, an engineer of PBD must consider various factors such as ignition location, ignition point, ignition source, first ignited item, second ignited item, flash over, the state of door and fire suppression system. But, it is difficult to trust fire safety capacity of the design because the process in Korea' PBD is unprofessional and unreasonable. This paper had surveyed some cases of PBD that had been made in Korea to find the problems of the process to predict fire risk. And it have proposed the improvements of process to predict fire risk of a building.

  • The current status of Performance-Based Design (PBD) implemented in 4 wide areas (Seoul, Gyeonggi, Incheon and Busan) over the past 5 years was reviewed with regard to the number of PBD implementation and target buildings. Then, detailed status related to fire scenarios, input information for fire simulation, and grid size were analyzed with the pre-review for the PBD. As a result, the domestic PBD was mainly applied to the mixed occupancy. In the fire simulations performed on the identical fire scenario and fire space, the maximum heat release rate (HRR) varied significantly depending on the PBD designer. Various combustibles were also considered for the identical fire source, and their combustion properties also showed considerable uncertainty. In addition, the applicability of accurate input information for predictive models of heat and smoke detectors was examined. Finally, the average grid size for the fire simulation using Fire Dynamics Simulator (FDS) was analyzed, and the improvement of PBD to minimize designer dependency was proposed.

  • Recently Korea has imported and executed Performance Based Design for the method to settle the dangerousness on outbreak of fire of high-rise building. The overseas country's PBD is autonomic but It is unable to carry out the essential role of PBD as the performance based design that based the code based design in the domestic. Also It occurs the problems that different the classification standard of building as dualisation between the building code and the fire services act. In this study, We have investigated overseas's cases for the PBD of high-rise building and have drawn the improvement direction & the problem of domestic's PBD by comparing and the analysing the domestic regulation.

  • 대규모 고층건축물에 대한 화재 및 피난 안전성을 강화하기 위해 2011년 7월 1일부터 성능위주설계가 시행되고 있다. 시행초기에 여러 가지 시행착오가 발생할 것으로 예상됨에 따라 본 연구에서는 성능위주 설계의 시행에 따른 문제점을 조사하고 개선방안을 제시하기 위해 관련 규정을 검토하고 소방전문가를 대상으로 설문조사를 실시하였다. 성능위주설계 대상에 일정규모 이상의 아파트와 주상복합건축물이 포함되어야 하며, 성능위주설계의 방법과 평가에 대한 명확한 기준 설정, 설계자 및 평가자에 대한 성능위주설계 관련 교육이 필요함을 확인하였다.

  • A performance-based design (PBD) procedure, initially proposed for the seismic design of buildings, is tailored herein to the structural configurations commonly adopted in bridges. It aims at the efficient design of bridges for multiple performance levels (PLs), achieving control over a broad range of design parameters (i.e., strains, deformations, ductility factors) most of which are directly estimated at the design stage using advanced analysis tools (a special type of inelastic dynamic analysis). To evaluate the efficiency of the proposed design methodology, it is applied to an actual bridge that was previously designed using a different PBD method, namely displacement-based design accounting for higher mode effects, thus enabling comparison of the alternative PBD approaches. Assessment of the proposed method using nonlinear dynamic analysis for a set of spectrum-compatible motions, indicate that it results in satisfactory performance of the bridge. Comparison with the displacement-based method reveals significant cost reduction, albeit at the expense of increased computational effort.

  • 최근 내구수명기간 동안 요구되는 성능을 만족시키는 차세대 구조설계 연구의 일환으로 PBD 방법에 대한 관심이 증가하고 있다. 성능의 유효여부를 결정하는 방법 중의 하나인 Bayesian 방법은 일반적으로 내진해석 및 설계에서 많이 사용되어왔다. 이 방법은 어느 지진가속도로 인해 발생할 수 있는 구조물의 한계상태(i.e. 붕괴)의 초과확률을 체계적으로 계산할 수 있는 통계방법이다. 이 연구에서는 Bayesian 방법을 활용하여 콘크리트 배합에 대한 강도, 워커빌리티, 탄산화 등과 같은 재료성능의 만족도를 만족 비율로 계산할 수 있는 PBD 개념을 개발하고자 한다. 설계 또는 분석에 사용될 수 있는 Bayesian 방법은 다양한 재료의 특성을 고려하여 만족도 곡선 작성 과정을 설명하고 작성된 만족도 곡선을 사용하는 방법을 제시하고자 한다.

  • 성능설계 시험 안을 작성하기 위해서는 건축물에 발생할 수 있는 화재의 크기를 정량화하는 단계가 선행되어야 한다. 이러한 설계화재의 크기가 적합하게 선정되었을 때 화재로부터 안전하면서도 경제적인 설계가 가능하다. 우리나라는 성능설계의 역사가 짧고 공학적 자료가 축적되어 있지 않아 화재의 크기를 선정하는 데에 많은 문제점을 드러내고 있다. 이에, 해외의 설계화재 가이드라인과 국내의 실 화재 실험 자료를 조사하였다. 그리고 국내의 설계화재 선정 사례를 조사하여 그 적정성을 분석하고 건축물의 용도별로 설계화재의 가이드라인을 제안하였다.

  • "Performance-based design (PBD)" is based on designing a structure with choosing a performance target under design criteria to increase the structure's resistance against earthquake effect. The plastic hinge formation is determined as one of the fundamental data in finite elements nonlinear analysis to distinguish the condition of the structure where more significant potential damage could occur. If the number of plastic hinges in the structure is increased, the total horizontal load capability of the structure is increased, also. Theoretically, when the number of plastic hinges of the plane frame structure reaches "the degree of hyperstaticity plus one", the structure will reach the capability of the largest ultimate horizontal load. As the number of plastic hinges to be formed in the structure increases towards the theoretical plastic hinge number (TPHN), the total horizontal load capability of the structure increases, proportionally. In the previous studies of the authors, the features of examining the new performance criteria were revealed and it was formulated as follows "Increase the total number of plastic hinges to be formed in the structure to the number of theoretical plastic hinges as much as possible and keep the structure below its targeted performance with related codes". With this new performance criterion, it has been shown that the total lateral load capability of the building is higher than the total lateral load capability obtained with the traditional PBD method by the FEMA 440 and FEMA 356 design guides. In this study, PBD analysis results of structures with frame carrier systems are presented in the light of the Turkey Building Earthquake Code 2019. As a result of this study, it has been shown that the load capability of the structure in the examples of structures with frame carrier system increases by using this new performance criterion presented, compared to the results of the examination with the traditional PBD method in TBEC 2019.

  • The purpose of this study is to develop Performance Based Design Method based on application of Fragility Method. Fragility Method has been used in predicting failure of structure due to seismic action, However, development of Fragility Curve based on material or construction for PBD is developed, This paper suggests that Fragility Method can be modified for PBD and can assess the performance of concrete material or construction.
