Historical masonry arch bridges which might be vulnerable to natural disasters are important part of the cultural heritage. Natural disasters, especially earthquakes can inflict damage these structural systems. This paper aims investigate a comparison effects near and far-fault ground motions on seismic response under different earthquakes. Kalender bridge is located in Ergani, Turkey selected ...

Special concentrically braced frames (SCBFs) located in regions close to earthquake faults may be subjected near-fault ground motions, often characterized by pulses with long periods. These could impose additional seismic demands on structures and increase the risk for structural collapse. Currently, there is limited research collapse of SCBFs under earthquakes. This paper uses a general simula...

[1] Low-velocity fault zones (LVFZs) are found in most mature faults. They are usually 100–400 m wide and have 20%–60% wave velocity reductions relative to the country rock. To study the effect of LVFZs on earthquake rupture and the radiated wavefield, we conducted two-dimensional (2-D) simulations of dynamic rupture on faults that bisect a LVFZ, considering a range of velocity reductions and w...

The paper discusses the fast seismic performance assessment of structures using truncated pulse-like ground motion records. It is shown that it possible to truncate a signal novel wavelet-based definition identifies duration predominant velocity pulse. time-history still able efficiently reproduce increased demand near-field records typically produce. Substituting original with signal, can sign...
