适用范围：(1) This Part 1-2 of EN 1994 deals with the design of composite steel and concrete structures for theaccidental situation of fire exposure and is intended to be used in conjunction with EN 1994-1-1 andEN 1991-1-2. This Part 1-2 only identifies differences from, or supplements to, normal temperaturedesign.(2) This Part 1-2 of EN 1994 deals only with passive methods of fire protection. Active methods are notcovered.(3) This Part 1-2 of EN 1994 applies to composite steel and concrete structures that are required to fulfilcertain functions when exposed to fire, in terms of:- avoiding premature collapse of the structure (load bearing function);- limiting fire spread (flame, hot gases, excessive heat) beyond designated areas (separating function).(4) This Part 1-2 of EN 1994 gives principles and application rules (see EN 1991-1-2) for designingstructures for specified requirements in respect of the aforementioned functions and the levels ofperformance.(5) This Part 1-2 of EN 1994 applies to structures, or parts of structures, that are within the scope ofEN 1994-1-1 and are designed accordingly. However, no rules are given for composite elements whichinclude prestressed concrete parts.(6) For all composite cross-sections longitudinal shear connection between steel and concrete should bein accordance with EN 1994-1-1 or be verified by tests (see also 4.3.4.1.5 and Annex I).(7) Typical examples of concrete slabs with profiled steel sheets with or without reinforcing bars are given in Figure 1.1.(8) Typical examples of composite beams are given in Figures 1.2 to 1.5. The correspondingconstructional detailing is covered in section 5.
