Nonlinear static procedures, which relate the seismic demand of a structure to that of an equivalent single-degree-of-freedom (SDOF) oscillator, are well-established tool [...]

RINTC, which started in 2015, is a joint project of ReLUIS and EUCENTRE, two centers of competence for seismic risk assessment of the Italian civil protection. The goal o [...]

Simplified computational tools for the seismic analysis of structures are often used within the framework of performance-based earthquake engineering. Substitution of a c [...]

Critical Infrastructures (CIs) provide essential goods and services for modern society; they are highly integrated and have growing mutual dependencies. Recent natural ev [...]

Probabilistic seismic risk assessment of civil infrastructures has been attracting attention in Japan, especially after recent mega-earthquakes with a long-lasting series [...]

Near-source ground motion records affected by “directivity” may show unusual features resulting in low frequency pulses in the velocity time-history, especially in th [...]

Feasibility of earthquake early warning systems (EEWS) depends on the possibility of immediately detecting the earthquake’s characteristics and on the ability to design [...]

Vector-valued ground motion intensity measures have been extensively investigated recently. Proposed measures are mainly related to pairs of spectral ordinates because th [...]

The USGS-PAGER Project is devoted to rapidly assess the consequences of severe earthquakes in the world. To improve the inventory and the vulnerability estimate, USGS mad [...]

Several different technical options are nowadays available to seismically upgrade an existing building. Selecting the best one with reference to a given structure general [...]
