For structural design of steel structures under seismic action there are two possible approaches of global analysis. In global analysis we can consider the structure to behave in linear elastic way or in post-elastic way with developing of plastic hinges during seismic situation. The second method is based on principle of seismic energy transformation into thermal energy. Both design methods are defined in Eurocodes but the post-elastic way is only rarely used because of design complexity. Application of this design method is presented in the entry on an example of a steam power plant boiler structure.
