In this study the integrated system for progressive collapse analysis, which can evaluate the damage level of every member and automatically construct the modified structural model for the next analysis step, has been developed. The existing nonlinear analysis program code OpenSees was used as a finite element solver in the integrated system for progressive collapse analysis. The developed inte...

Many recent research studies focused on the development of innovative seismic resilient structures by chasing objectives minimising both damage and repair time, hence allowing definition able to go back undamaged, fully functional condition, in a short time. In this context, present study investigates an type self-centring damage-free steel column base (CB) connection its beneficial effects whe...

Pile foundations is a well-studied technique with many applications and its benefits on structures have been widely studied in the literature. In particular, mutual effects of pile flexibility soil deformability may significantly modify seismic behaviour superstructures. order to consider uncertainties that are connected these issues, paper applies probabilistic-based approach fragility curves ...

Aging highway infrastructure requires effective rating methodologies to prioritize bridges for rehabilitation and repair. To aid engineers in decision making regarding bridge maintenance, a three-dimensional 3D visualization system is developed for rating reinforced concrete deck-girder bridge. Color codings show the most probable mode of failure for girder cross sections under combined moment-...

The role of abutments on the seismic vulnerability bridges has been relatively little studied in geotechnical literature. To cover this gap, 3D numerical simulations were herein performed, by studying performance three single-span bridge configurations. models used OpenSees to account effects due soil structure interaction between deck and abutments. In particular, advanced materials implemente...
