  • Performance based design is a recent evolutionary step in the process of designing fire protection systems. In essence, it is a logical design process resulting in a solution that achieves a specified performance. Sometimes the prescriptive solutions presented in various codes and standards are too expensive or inflexible. Often the solutions do not and enables optimization of a solution for cost and function. In this study, performance based design was carried out to determine the extent of passive fire protection for oil terminal facilities. The results of performance based design were compared with those of prescriptive code based design. Performance based design is not always more economic than prescriptive code based design but provides more reliable and effective design that is fit for the purpose.

  • Placement method for fire detectors prescribed in current fire safety regulation is just about placing a prescribed number of detectors according to the areas. However, this regulation has no scientific basis and standards from foreign countries are just introduced and fire detectors are installed complying with them. There are two standards in designing fire protection systems; Prescriptive-Based Design that follows stipulated regulations like fire safety standards and Performance-Based Design based on engineering knowledge such as fire dynamics, structural dynamics, mechanics of materials, fluid mechanics, and thermo dynamics. Recently, Fire Protection System Construction Business Act was revised so that fire protection systems can be designed using Performance-Based Design method ('05. 8. 4), though the method has not activated until now. In addition, the enforcement decree defines the range for specific objects of fire protection to which Performance-Based Design is applied ('07, 1. 24). At the moment, by manufacturing simulator so that formulas can be introduced and calculated with software in order to install fire detector of automatic fire detection systems keeping optimized distance, comparing the results with the state of fire detector placed according to Performance-Based Design and analyzing them, this study was intended to settle Performance-Based Design method in the future.

  • This paper presents a state-of-the-art review on the design, research and education aspects of fire safety engineering (FSE) with a particular concern on high-rise buildings. FSE finds its root after Great Fire of Rome in 64 AD, followed by Great London Fire in 1666. The development of modern FSE is continuously driven by industry revolution, insurance community and government regulations. Now FSE has become a unique engineering discipline and is moving towards performance-based design since 1990s. The performance-based fire safety design (PBFSD) involves identification of fire safety goals, design objectives, establishment of performance criteria, and selection of proper solutions for fire safety. The determination of fire scenarios and design fires have now become major contents for PBFSD. To experience a rapid and positive evolution in design and research consistent with other engineering disciplines, it is important for fire safety engineering as a profession to set up a special educational system to deliver the next-generation fire safety engineers. High-rise buildings have their unique fire safety issues such as rapid fire and smoke spread, extended evacuation time, longer fire duration, mixed occupancies, etc., bringing more difficulties in ensuring life safety and protection of property and environment. A list of recommendations is proposed to improve the fire safety of high-rise buildings. In addition, some source information for specific knowledge and information on FSE is provided in Appendix.

  • 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.

  • In Korea, the relevant laws and regulations for fire safety in buildings have been revised. Since 2011, Performance-based Design has been conducted for large-scale or high-rise buildings. However, the Korea's performance-based design is still at a level where life safety evaluation using fire and evacuation simulation tools is compared with existing methods. Although related studies have been conducted continuously for the mandatory performance-based design, the fact that it is relatively unsatisfactory for design and construction of fire-fighting facilities as it mainly focuses on administrative and institutional improvement measures or computer simulation. This study collected 91 performance-based design documents that were carried out nationwide at the initial stage of implementation until 2016 to analyze the status of performance-based design of fire-fighting facilities. As a result, fire-fighting facilities, except for fire extinguish system facilities, were not properly designed for performance. Furthermore, the designers found that if corresponding facilities or higher-level equipment with upgraded performance is additionally installed, the performance-based design fared well compared to the existing the prescriptive-based design.

  • Today's building and fire prevention codes are mostly prescriptive. Prescriptive codes are based on major fires in earlier years that created a need for specific building provision. These codes provide a minimum level of safety. As the general and engineering uses of computers have increased over the years, so has use of computers in the fire protection engineering. This has allowed fire protection engineers to develop alternative approaches to solve today's fire protection problems or to evaluate the performance of a specific fire safety goal. A performance based approach to building and fire codes involves the following: 1) identifying specific goals, such as, safely getting out of the building in 10 minutes, 2) obtain conceptual approval from authorities, 3) define performance level, 4) develop design solutions and identify tools such as, fire tests, models, or methods, to demonstrate that a design will meet the fire protection objective 5) test solutions, 6) present test method and results to the authorities. Some people in the fire protection community consider this to be nothing more than an intellectual exercise, while the others view it as a way to reduce expenses on large project$^4$ Others in fire protection community view this as a way to refine the design process to design fire protection systems to better protect the fire hazards. This paper will focus on application of these tools, specifically computer fire models, to actual cases such as: design of a smoke control system heat transfer analysis and egress of building occupants during potential fires.

  • The buildings relevant to the law should be designed performance-based necessarily according to "Fire-Fighting System Installation Business Act" amended, January 1. 2009. Performance based design means that building design reflects structure, size, purpose, and building capacity to achieve the most effective design of fire-fighting system. Performance based design has meaning to buildings that it is insufficient to control fire-fighting by previous law-oriented design or inappropriate by uniform design, because of buildings becoming bigger and higher. However, it is difficult to implement the system actually, because laws relevant to fire-fighting prescribe only the object and the required qualifications of performance based design, but they don't have rules to enforce performance based design for specific parts. This study suggests improvements for a desirable implementation of performance based design in legal aspects, by analyzing the current legal regulations related to performance based design.
