Abstract in English
Most existing structures are not designed with cod
requirements to meet seismic risk, Therefor methods for
strengthening and stiffening existing buildings are important .
This study is comparing between strengthening by adding shear
wall or by adding steel bracing.X -V
The study shows the importance of using steel bracing system
that is excellent approach for strengthening and stiffening
existing buildings with small increase in mass ,the study also
approved that the constant value of R(response factor)(as
mentioned in the Syrian code and UBC97) is not completely
correct.
