Under seismic actions, the structures undergo two simultaneous horizontal components of the ground motion, which cause a structural response in an oblique direction and b [...]

In several earthquake-prone countries, many buildings have not been designed by seismic regulations and others have been constructed according to old seismic codes. Effec [...]

In the world, many existing buildings with RC framed structure were designed according to old seismic standards and, consequently, present structural deficiencies. Embedd [...]

For a long time, the structural model of r/c framed structures has been defined assigning to each member a conventional stiffness, related to the properties of the geomet [...]

A large part of existing buildings in the world has been designed without considering seismic provisions. These buildings are generally not adequate to resist seismic for [...]
