Near-fault earthquakes (NFEs), characterized by high peak ground velocity (PGV) and long period pulses, show different properties from far-field ones. The input motions from NFEs are usually composed of a small number of sinusoidal large waves in addition to significant vertical components. These specific characteristics of NFEs strongly influence the seismic response of civil infrastructure and may reduce the effectiveness of the adopted protection devices. This Special Issue aims to introduce the latest advances regarding the effects of near-fault ground motions on civil infrastructure. Ten papers on various aspects of near-fault ground motions, including the response of different bridge typologies (i.e., cable-stayed, integral abutment, curved and girder with composite tall piers), nuclear power plants, dams, the stability of rocking rigid blocks and energy-based approaches for seismic design, are presented in the Special Issue. Throughout the world, the durability of existing bridges is an important issue. Integral abutment bridges (IABS) are characterized by a reduction in maintenance due to the elimination of bearings and expansion joints. In the meantime, there is still a lack of knowledge regarding their seismic behavior that is influenced by the soil-structure interaction. [PERSON] et al. [1] investigated the seismic response of skewed integral abutment bridges subjected to NFEs. The obtained results show that NFEs are generally more dangerous than non-pulse motions for skewed IABs. Energy-based approaches can be particularly well suited for the analysis of structural systems subjected to NFEs. In the study by [PERSON] et al. [2], a comprehensive numerical investigation of the influence of seismological parameters and hysteretic behavior on the spectra to be used for the energy-based seismic design was performed. The following energy-related parameters were investigated: the inelastic absolute and relative input energy; input energy reduction factor; hysteretic energy dissipation demand; hysteretic energy reduction factor; and dimensionless cumulative plastic deformation ratio. Hybrid steel-concrete solutions have been recently used for tall bridge columns built in high-seismic zones. A tall-pier system composed of four concrete-filled steel tubular (CFST) columns and energy-dissipating mild steel plates (EDMSPs) subjected to NFEs was studied by [PERSON] et al. [3]. Numerical investigations were performed using the commercial software Midas Civil2019 and ABAQUS. The results confirmed the good performance of the proposed hybrid solution under near-fault ground motions. In recent years, many cable-stayed bridges have been built in earthquake-prone zones. [PERSON] et al. [4] investigated the seismic behavior of a cable-stayed bridge with a main span of 680 m under NFEs, carrying out shaking table tests on a 1/100 scale model. The influence of non-pulse near-field and velocity-pulse near-fault ground motions was reported.
