Project is developed by Green Technology Island Properties Limited, it’s a set of mercial, office, LOFT office plex real estate projects. Among them, the 27story Grade A office building has rooms with 70120m178。 percell, it’s building height is and construction area ??is 33395 m178。. The service life period of this building is 50 years. This paper does research on contents as follow, (1) analysis of situation of highrise building’s fire safety at home and abroad。 (2) the significance of this paper。 (3) general layout of fire control。 (4) smoke control design。 (5) Evacuation design 。(6) fire extinguisher。 (7) fire water supply system design。 (8) automatically spray fire distinguish system。 (9)fire automatically alarm system.This design mainly involves the standard code for fire protection design of buildingsGB500162006, fire protection design of tall buildingsGB5004595, for design of automatic fire alarm systemGB5011698, code for design of sprinkler systems GB500842001, code for Design Regulations on fire prevention in garage, repair shop, and parking lotGB5006797, code for design of architectural specification extinguisherGB501402005, Office building designJGJ672006.In accordance with the standard code for fire protection design of buildings, this building has been rated as the first class public building, and its fireresistance rating as the first level. The fireproof distance between this building and other highrise buildings should be 9m, while between the building and other residence and podium should be 13m. Set ring fire road around the building.In accordance with structure and use of this building and national regulations and rules, the general layout of fire control of this building mainly designs the fireproof part and smokeproof part of functional division inside each other floor. The safe evacuation route is from room to hallway to antechamber to stairwell. Each fire district located two evacuation exits and walkway’s width is , two security exit distances greater than 5m, the safe evacuation distance is , which is pliance. Each tower set two stairwells, a fire elevator in design.Design objects is serious risk hazard level, it is mainly made for fire emergency of A class, and few for E class. Fire extinguishers are equipped with ammonium phosphate powders (MF/ABC5) and hands holder. Fire minimum configuration level is 3A, and maximum protection distance of hands holder is 15 meters. According to the result of puting protected area square and fire protection levels, fire extinguishers set 4 point in the first floor to the 27th floor, 17 point in the basement, 8 fire extinguishers in the first floor and 3th floor to the 27th floor, 4 fire extinguishers in the second floor and 17 fire extinguishers in the basement.Fire water supply system design includes the outdoor fire hydrant system and indoor fire hydrant system. Outdoor fire hydrant water consumption is 30L / s, set three outdoor low voltage ground fire hydrant. Indoor fire hydrant water consumption is 40L / s. The waterpower calculation of full water spout is12m, fire hydrant protective radius is 28m, fire hydrant distance is , setting up 5 risers in building. The total loss is , the elevation difference between most negative point hydrant and lowest level of fire pond is , working pressure of the fire fighting equipment at the most negative point is , so the fire pump lift is 150m and flow is , choose 8 model of fire pump, with a preparation, set 4 fire pump adapter. Set a fire pond, the effective volume of it is 435m3. Set fire water tank, the effective volume of it is 28m3, no booster facilities.The autospray system adopts the design of wettype autospray fire extinguishing system. In accordance with regulations and rule, this building is regarded as I class of danger categories. This design chooses the
