  • 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.

  • Performance-based design (PBD) for large scale high rise buildings has been enforced to secure fire and evacuation safety since July 1, 2011. As various types of trial and error were expected in the early stage, to suggest solutions to the problems that might be followed by the enforcement, the regulations on PBD were reviewed and a questionnaire survey to fire protection specialists was carried out. It was confirmed that PBD is required for large scale apartment buildings, and specific and detail criteria for PBD methodology and evaluations, education for PBD to personnel who design and evaluate are also in need.

  • 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.

  • Recently, Performance Based Design (PBD) method has been studied as a next generation structural design method, which enables a designed structure to satisfy the required performance during its service life. One method of deciding whether the required performance has been satisfied is Bayesian method, which has been commonly used in seismic analysis. Generally, it is presented as a conditional probability of exceeding some limit state (i.e., collapse) for a given ground motion. In PBD of concrete mixture design, the same methodology can be applied to assess concrete material performance based on some conditional parameters (i.e. strength, workability, carbonation, etc). In this paper, a detailed explanation of the procedure of drawing satisfaction curve by using Bayesian method based on various material parameters is shown. Also, a discussion of using the developed satisfaction curves for PBD for concrete mixture design is presented.

  • The quantification of fire size in buildings must be preceded in order to design the trial of performance based design (PBD). When design fire size is determined appropriately, the trial design will become economical and safe design against fire risk. There are many problems in determining design fire size because of lacks of fire engineering data and short history of PBD in korea. Therefore, this paper has surveyed the guideline of design fire in other countries, real experimental data for a few occupancies and the cases of design fire size determining for PBD in Korea. Also, it has proposed the guideline of design fire size for various occupancies in korea after analyzing the appropriateness of design fire size.

  • "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.
