Squat reinforced concrete (RC) walls are essential structural components in nuclear power facilities (NPP) and in many civil structures. An adequate prediction of the shear strength and displacement capacity of these ...

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 ...

Congestion and safety problems at intersections have been on the rise due to the increased traffic volumes throughout mainline corridors in Puerto Rico, as well as in the United States. As a result, new and innovative ...

The knowledge of the natural periods of soil deposits in urban areas can be very valuable for the safe design of structures to avoid resonance conditions. This thesis presents a study aimed to estimate site natural periods ...

Recent regulations in the nuclear industry have imposed the consideration of high frequency ground motion effects in the construction and evaluation of nuclear power plants. The uniform hazard spectra used for Central and ...

The coast of Rincón, Puerto Rico, has been experiencing long-term erosion for the last several decades. The purpose of this research is to evaluate the Bajo Blanco sand shoal, located just offshore of these eroded beaches, ...
