کاوشی در ارزیابی آسیب پذیری و بهسازی لرزه ای ساختمان ها در تراز پی برمبنای ضوابط دستورالعمل بهسازی لرزه ای

Abstract:
The experience of last earthquakes has shown the vulnerability of most of structures. This has
been caused the speeding up of the seismic evaluation and retrofitting of projects in Iran. In
this regard, the instructions for seismic rehabilitation of the existing buildings have been
published and are currently beiong used in the evaluation and retrofitting projects. The
experience of retrofitting the structures in the past has shown that one of the most important
problems in Iran is seismic evaluation and retrofitting of the foundations. The evaluation
procedures are usually done such that they results in huge retrofitting plans for foundations
and this opinion has been raised that seismic evaluation and retrofitting of the structures is not
economical. This paper presents some suggestions for accurate seismic evaluation of
structural and geotechnical components of foundations. The results showed that by using the
correct relations and understanding the behavior of structure exactly, the retrofitting
procedure do not result in massive strengthening.
