in recent years, seismic evaluation and vulnerability of the existing buildings, that have been designed based on an earlier seismic design code or designed without seismic design criteria, has been very important. in this paper, the seismic evaluation and vulnerability of concrete buildings, using an old 5- story building with shear walls as an example has been discussed. for this building, fi...

Structures subjected to seismic forces must have adequate strength and stiffness to control inter storey drift in order to prevent damage to structural and nonstructural elements during excitations. Linked column concept for steel structures was proposed by Peter Dusicka et.al(2009) with the objective of utilizing replaceable components that are strategically placed to protect the gravity load ...

During the 2011 Tohoku Earthquake, gymnasium buildings sustained unexpected structural damage, preventing their use as evacuation shelters. This study examines one such severely damaged structure with fewer connections between steel roof and reinforced concrete columns. Results of eigenvalue, pushover, seismic response analyses elucidate observed damage. The out-of-plane deformation is prominen...
