abstract
The structural safety is one of the most important issues in construction. In order to ensure this safety there is a need to provide the appropriate carrying capacity to the structure. One of the initial stages of the design process is the quantification and combination of the different actions.
Eurocodes 0 and 1 (EN 1990, EN 1991) are concerned by defining the basis of structural design and the actions that should normally be considered in the design of buildings and civil engineering works such as imposed load, wind and snow loads, and have brought a consistency of methodologies for structural design across European Union. Switzerland is one of the few countries in Europe which is not included in European Union, and that continues to follow internal standards, the SIA - Swiss Society of Engineers and Architects.
Current investigation involved the comparative study of the requirements for safety and serviceability limit states, load combination format, and partial safety factors as well as the main actions to be considered for the structural design and verification. Both codes of practice are analyzed and compared for the different actions. An automatic calculation computer program was also developed during this study in order to estimate the values of the different actions.
Finally, a real building was modelled so as to validate the above mentioned program and to analyze the main differences between European and Swiss codes.
