The goal of this paper is to develop a new empirical relationship between observed macroseismic intensity and strong ground motion parameters such as peak acceleration (PGA) velocity (PGV) for the Vrancea subcrustal earthquakes. recent earthquakes provide valuable data examine these relationships seismogenic region. This region one most active seismic zones in Europe it well-known We correlatio...

To study the ground motion level associated with historical earthquakes located in Southern Spain, we have chosen a scenario placed in the Poniente Almeriense (Southeast Spain). In this zone, some relevant historical earthquakes have occurred, such as those of 1522, 1804 and 1910. In particular, the earthquakes of 1804 and 1910 the estimated and calculated magnitudes are of M = 6.3. Those earth...

This article outlines a new approach to rapidly estimate the damage to tall buildings immediately following a large earthquake. The preevent groundwork involves the creation of a database of structural responses to a suite of idealized ground-motion waveforms. The postevent action involves (1) rapid generation of an earthquake source model, (2) near real-time simulation of the earthquake using ...

Large changes in stiffness associated with cracking and yielding of reinforced concrete sections may be expected to occur during the dynamic response of reinforced concrete frames to earthquake ground shaking. These changes in stiffness in stories that experience cracking might be expected to cause relatively large peak interstory drift ratios. If so, accounting for such changes would add compl...

The main focus of this research has been to investigate the effectiveness of optimal single and multiple Tuned Mass Dampers (TMDs) under different ground motions as well as to develop a procedure for designing TMD and MTMDs to be effective under multiple records. To determine the parameters of TMD and MTMDs under multiple records various scenarios have been suggested and their efficiency has be...

[1] ElarmS is a network-based methodology for rapid earthquake detection, location and hazard assessment in the form of magnitude estimation and peak ground motion prediction. The methodology is currently being tested as part of the real-time seismic system in California leveraging the resources of the California Integrated Seismic Network (CISN) and the Advanced National Seismic System. A tota...
