This paper presents a suitable and quick way to choose earthquake records in non-linear dynamic analysis using optimization methods. In addition, these earthquake records are scaled. Therefore, structural responses of three different soil-frame models were examined, the change in maximum displacement of roof was analyzed and the damage index of whole structures was measured. The soil classifica...

The updated version for the Manual of Civil Structures (MOC), a model seismic code in Mexico, was published in 2008. MOC also is incorporating guidelines for the seismic design of base-isolated structures this year 2012, being the first Mexican code to include such recommendations. This paper summarizes the most relevant aspects of these guidelines, their relations to other guidelines worldwide...

Recent studies have indicated the need of considering aftershocks in seismic design/assessment structures. This article investigates effect sequential mainshock and aftershock earthquakes on eccentrically braced steel frames with vertical energy-absorbing links. To achieve this, 4, 8 12-storey frame buildings are modelled Perform3D® software non-linear behaviour materials components. The subjec...

In present study, the effects of optimization on seismic energy spectra including input energy, damping energy and yielding hysteretic energy are parametrically discussed. To this end, 12 generic steel moment-resisting frames having fundamental periods ranging from 0.3 to 3s are optimized by using uniform damage and deformation approaches subjected to a series of 40 non-pule strong ground motio...

Growing financial failure at firm-level can have serious consequences for banks in terms of rising non-performing assets, the absence a strong bankruptcy system. Such scenario India made its dysfunctional insolvency system to be reformed, introducing new Insolvency and Bankruptcy Code (IBC) 2016. Using panel 33,845 Indian firms over period 2008–2019 by employing difference-in-differences approa...
