This thesis examined an approximate method to calculate the nonlinear seismic response of structures known as the Equivalent Linear Model (ELM) which seeks to approximate the true nonlinear response through a series of ...

Pulse-like earthquakes are believed to impose larger structural demands on structures due to the sudden release of seismic energy. This can cause concern in areas that are near fault due to the possibility of structures ...

Los códigos actuales de diseño son cada vez más estrictos para el diseño de las estructuras que necesitan mantenerse operando continuamente durante un evento de terremoto. Las estructuras tales como hospitales, edificios ...

The wind energy industry has seen a substantial growth in several industrialized countries in recent years. Traditionally, territories in northern Europe, with a low level of seismicity, have been the leaders in the use ...

The Commonwealth of Puerto Rico has over 2200 in-service bridges as part of their inventory and more than 50% of these bridges were constructed over 30 years ago. Seismic design requirements are updated frequently due to ...

Due to the latent risk that exists in seismically active areas such as Puerto Rico, which is located on the border between the North American and Caribbean plates, it is important to be aware of the performance of the most ...

Reduced scale models of a single span bridge, a 12 bay truss bridge, and a numerical model of a multi-story shear building were used to evaluate the capability of Wavelet Transforms for damage detection and system ...

To assure the safety of Nuclear Power Plant structures, it is crucial to design them in a way that guarantees the continuous function of systems, structures, and components (SSC) after the seismic event has passed. Seismic ...

Seismic designed structures are expected to resist minor level earthquakes without significant damage as well as major level earthquakes without collapse. Over the last years the number of seismic instrumentation networks ...

The equivalent linear method is widely used in Geotechnical Earthquake Engineering to calculate the accelerations at the surface of soil deposits subject to earthquakes of moderate intensity. The method approximately takes ...
