Abstract This work presents an up-to-date model for the simulation of non-stationary ground motions, including several novelties compared to original study Sabetta and Pugliese (Bull Seism Soc Am 86:337–352, 1996). The selection input motion in framework earthquake engineering has become progressively more important with growing use nonlinear dynamic analyses. Regardless increasing availability...

We performed simulations of ground motions in Mexico City expected for large earthquakes in the Guerrero seismic gap in Mexico. The simulation method uses as empirical Green's functions the accelerograms recorded in Mexico City during four small to moderate earthquakes (8 Feb. 1988, M s = 5.8; 25 April 1989, M w = 6.9; 11 May 1990, M w = 5.5; and 31 May 1990, Mw = 6.0) in the Guerrero gap. Beca...

Computer simulations are challenging in terms of modeling the appropriate behavior brick masonry structures. These numerical becoming increasingly difficult due to several design code requirements considered for technical assessment structures rehabilitation. In Romania, many have withstood powerful earthquakes during their lifetime and require rehabilitation works. This paper aims further asse...

Code response spectrum models, which are used widely in the earthquake-resistant design of buildings, simple to apply but they do not necessarily represent real behavior an earthquake. A code model typically incorporates ground motion a diversity earthquake scenarios affecting site and does any specific scenario. The soil amplification phenomenon is also poorly represented, as current classific...

ONE OF the most important problems in the field of earthquake engineering deals with the dynamics of structures. Any building is an elastic system. As such, its deflections (stresses) during an earthquake may depend on its own dynamical characteristics as well as on the nature of the ground motion. An ordinary building is a relatively complicated dynamic system, usually of many degrees of freed...

Seismic risk assessment of new and existing structures has a long history, which is based on the development specific methods for seismic hazard vulnerability analyses. Performance-based earthquake engineering natural evolution integration all these aspects that nowadays implemented in several precodes. However, some critical are not yet completely clarified. As matter fact, analysis suffers so...

Introduction . The present article concerns the seismic performance of various building structures, including NPP objects. provided materials generalize results author’s longstanding work connected with dynamics structures. Aim To analyze objects, and represent material on Materials methods presented include a definition concept, computational modeling dynamic processes, main correlations analy...

The variation of earthquake input energy with characteristics of various structural systems, particularly in hysteretic states, has not been studied to such extent that creates enough con-fidence for proposing energy-based design criteria. In this paper, at first, based on a somehow new insight into the concept of earthquake input energy, two concepts of ‘Received Energy’ (ERec) and ‘Returned E...
