If special national standards are available, the fire protection design of buildings for civil air defense engineering, petroleum and natural gas engineering, petrochemical engineering, thermal power plants and substations should comply with such standards. 1.0.3 This code is not applicable to the fire protection design of buildings such as factory-buildings (storages) for gunpowder, explosive and their products as well as fireworks and firecrackers. 1.0.4 Where occupancies for different purposes are arranged in the same building, fire separation shall be provided between them. The fire protection design for this building and their functional occupancies shall be determined according to the relevant requirements of this code. 1.0.5 The fire protection design of buildings shall comply with the relevant national principles and policies, and guarantee, on the whole, safety and usability, advanced technology as well as economy and rationality according to the characteristics of buildings and fire hazards in them. 1.0.6 In addition to meeting the requirements of this code, the buildings with height single-storey Category D factory-buildings with building area not greater than 1,000m2, the fire resistance class may adopt Class III. 3.2.4 As for the buildings using or storing particularly valuable equipment or articles such as machinery, instruments and apparatuses, the fire resistance class shall not be less than Class II. 3.2.5 The fire resistance class of boiler house shall not be less than Class II. In case of coal-fired boiler house with total evaporation not larger than 4t/h, its fire resistance class may adopt Class III. 3.2.6 The fire resistance class of oil immersed transformer room and high-voltage distribution device room shall not be less than Class II, and other fire protection design shall meet the requirements of current national standard "Code for Design of Fire Protection for Fossil Fuel Power Plants and Substations" (GB 50229) and other relevant standards. 3.2.7 The fire resistance class of high rack storages, high-rise storages, Category A storages, multi-storey Category B storages and multi-storey Category C storages storing combustible liquid shall not be less than Class II. The fire resistance class of single-storey Category B storages, single-storey Category C storages, multi-storey Category C storages storing combustible solids and multi-storey Categories D and E storages shall not be less than Class III. 3.2.8 The fire resistance class of grain silos shall not be less than Class II; the grain silo with Class II fire resistance may adopt steel silo. The fire resistance class of grain storehouses shall not be less than Class III; the bulk grain storehouses with Class II fire resistance may be adopted with metal load-bearing elements without fire protection. 3.2.9 The fire resistance rating of fire walls in Categories A and B factory-buildings and Categories A, B and C storages shall not be less than 4.00h. 3.2.10 The fire resistance rating of columns in single-storey factory-buildings (storages) with Class I or II fire resistance shall not be less than 2.50h and 2.00h respectively. 3.2.11 As for the Class I fire resistance single-/multi-storey factory-buildings (storages) with full protection of sprinkler system, the fire resistance rating of their roof load-bearing elements shall not be less than 1.00h. 3.2.12 Except Categories A and B storages and high-rise storages, if the non-load-bearing exterior walls of buildings with Class I or II fire resistance adopt non-combustible wall body, their fire resistance rating shall not be less than 0.25h; if they adopt difficult-combustible wall body, their fire resistance rating shall not be less than 0.50h. As for the 4-storey or less Categories D and E over-ground factory-buildings (storages) with Class I or II fire resistance, if their non-load-bearing exterior walls adopt non-combustible wall body, their fire resistance rating is not limited. 3.2.13 As for factory-buildings (storages) with Class II fire resistance, if the partition wall between rooms in them adopt difficult-combustible wall body, the fire resistance rating shall be increased by 0.25h. 3.2.14 As for the prestressed reinforced concrete floor slabs in multi-storey factory-buildings with Class II fire resistance, the fire resistance rating shall not be lower than 0.75h. 3.2.15 As for the accessible flat roof of factory-buildings (storages) with Class I or II fire resistance, the fire resistance rating of the roof slab shall not be less than 1.50h and 1.00h respectively. 3.2.16 The roof slab of factory-buildings (storages) with Class I or II fire resistance shall be made of non-combustible materials. The roof waterproof layer should adopt non-combustible or difficult-combustible materials. If combustible waterproof materials are adopted and laid over combustible or difficult-combustible thermal insulation materials, the waterproof materials or the combustible/difficult-combustible thermal insulation materials shall be protected with non-combustible materials. 3.2.17 If it is necessary to adopt metal sandwich panels as the non-load-bearing exterior wall, partition walls between rooms and roof slab in buildings, the core material shall be non-combustible and its fire resistance rating shall meet the relevant requirements of this code. 3.2.18 Unless otherwise stated in this code, the fire resistance class of such factory-buildings (storages) with load-bearing wooden columns and with walls made of non-combustible materials may be determined as Class IV. 3.2.19 Proper fire protection measures shall be taken at the exposed joint positions of precast reinforced concrete elements, and the fire resistance rating of joints shall not be less than that of corresponding elements. values stated in this table and it is indeed difficult to build fire.......Source: https://www.ChineseStandard.net/PDF.aspx/GB50016-2018 |
