NATIONAL INTRODUCTION  
Supplement SIST EN 1992-1-2:2005/A101, Eurocode 2: Design of concrete 
structures – Part 1-2: Gener al rules – Structural fire design – National  annex, 2009, 
has the status of supplement to standard SIST EN 1992-1-2:2005.  
NATIONAL PREFACE  
The Slovenian national standar d SIST EN 1992-1-2:2005 is  an adapted version of 
European standard EN 1992-1-2:2004, prepared by the European Committee for 
Standardization Technical Committee CEN/TC 250 - Structural Eu rocodes, with its 
secretariat at the BSI. 
The supplement SIST EN  1992-1-2:2005/A101:2009 was pr epared by the SIST/TC 
KON Technical Working Party (Construction). 
This supplement may be used together with standard SIST EN  1992-1-2:2005 and/or 
EN 1992-1-2:2004, which under Na tional Annex stipulates items where the national 
option may be exercised. 
National options are permitted for th e following items of EN 1992-1-2:2004:  
2.1.3 (2)  
2.3 (2)P 
3.2.3 (5) 
3.2.4 (2)  
3.3.3 (1)P 
4.1 (1)P 
4.5.1 (2) 
5.2  (3) 
5.3.2 (2)  
5.7.3 (2) 
6.1 (5) 
6.2 (2) 
6.3 (1)P 
6.4.2.1 (3) 
6.4.2.2 (2) 
The national annex contains alternative pr ocedures, values and recommendations for 
the classes with notes indicating where the European standard stipulates that 
national options may be exercised.  The national anne x SIST EN 1992-1-
2:2005/A101:2009 therefore contains the nati onally agreed parameters that must be 
applied when designing construction works to  be built in the Republic of Slovenia. 
The decision to issue this supplement was adopted on ______  [date] by the SIST/TC 
KON Technical Working Party (Construction).
