Abstract
In this paper we analyze a structure’s response to new loadings in conformity
with the new codes. In order to be able to come to a relevant conclusion we
analysed three cases: a) strengthening the elements so that it keeps the same
configuration, b) strengthening the elements and modifying the moment resisting
frames into braced frames and c) reconstruct the entire structure with new
elements. By applying the new codes we have analysed the results and we
present the conclusions and the best and optimum solution for this particular
case.
Keywords: retrofit, comparison to old codes, structure response, moment
resisting frames, braced frames, sustainability.
1 Introduction
The Rovinari energetic complex in Romania is one of the biggest producers of
electric (1320 MW) and thermal energy using coal as primary source of fuel.
That is why in order to comply with the requirements of the Plan for the
implementation of the EU Directive 1999/31 on storage of residual waste, it is
imperative to introduce certain installations for the evacuation of coarse slag and
ash, by using the technology of the self-hardening fluid. There are four energetic
blocks each of 330 MW. For each block the ash and the slag are collected in a
silo of 500 m3. This silo leans against a metallic structure, which is to be
analysed in this paper. On this structure, supplementary installations for the
evacuation of coarse slag and ash have to be mounted. Because of the short time
at our disposal and because the silos cannot be dismounted, it is imperative to
find a solution to retrofit the existent metal structure without interrupting the
production process. The existent metal structure was designed in 1972 and that is
