2. Frame Work Development of performance design
The Korean Standard of performance design regulates "for the structure to verify performance of fire resistance structure based on the performance design sanctioned by "the Director of Korea Institute of Construction Technology as descried in "Rule for the Standard of Evacuation and Fire Protection Structure etc of Buildings (May, 2011)" Article 2 and Item Na.
The standard shows the background for performance design during fire resistance design of buildings but, the frame work to determine its status, structure etc of performance design standard should be presented to implement those performance designs. Therefore, this study is to propose a frame work of performance design appropriate in Korea through a merit and a demerit analysis of each country's performance design standard.
In the result of the analysis of each country's standard and New Zealand's performance design standard, the performance design is intended to divide into evaluation standard of performance design and implementation method of performance design. The evaluation standard of performance design can be proposed in consideration of a fire protection district and a load bearing capacity of structure member and the implementation method of performance design can be proposed with actual size experiment, fire engineering and theoretical anticipation and simulation of fire analysis. In consideration of the status and characteristics of the New Zealand's regulations and current Korea regulations, Korean performance design standards are proposed as ① Enactment/Revision on Evacuation and Fire Protection Structure Rule [prepare legal background], ② Notice of Ministry of Land, Transport and Maritime Affairs, ③ Korea Standard (KS, Special method), ④ Alternative performance design method [manual: general method]

3. Proposal of fire resistance design based on building performance
Critical considerations as a performance design process applied to general architecture are a building height, plane plan, opening, distance to close building, fire hazard classification etc.
However, because a building life become longer by a development of structure materials, method etc, usage of building, resident characteristic, use purpose etc can be replaced.
Therefore, a flexible design is required to easily change the design for the fire safety system.
- Step 1: Determination of design purpose for the buildings [new construction, reconstruction, extension of building, remodelling etc]
- Step 2: Acceptance of demand by user (client) [determination of building characteristic
- Step 3: Classification of building use & fire hazard (FHC)
- Step 4: Determination of occupant density and accommodation number
- Step 5: Determination of the design of fire protection district [number of fire protection district and performance standard of fire protection district (F)] and fire safety system (FSP)
- Step 6: Determination of standard for load bearing capacity during the fire of building structure members (S)
- Step 7: Determination of required fire resistance performance for each building structure member (FRR: load bearing capacity/flame interruption performance/fire interruption performance) and implementation of fire resistance design for structure member [fire resistance design of the object structure member (experimental and theoretical analysis)]
- Step 8: Inspection and evaluation for a fire resistance design of building structure members

4. Fire resistance method for performance concept introduction of building [performance design tool]
To secure reliability of theory formula to compare with the verification and actual size experiment result of fire resistance design standard for the structure currently introduced and enacted in Korea, calculation tool for the performance evaluation of fire resistance structure is required to briefly evaluate the fire resistance performance during a fire of a structure member. Therefore, for this study, a calculation tool development is required applying theory formula of performance design easily, repeatedly and briefly used by structure designer not fire experts.
Consequently, the fire resistance performance of the object structure member can be evaluated in the fire district office and the calculation tool for alternative fire resistance design applying fire engineering theory formula has been developed.
