dc.description.abstract Tsunamis are a rare yet powerful oceanic events consisting of a series of very long waves caused by a large-scale disturbance of a body of water, usually by earthquakes, that travel inland causing a tremendous amount of damage to anything that lies in its path and flooding entire areas. The most common trigger for tsunamis is earthquakes below or near the ocean floor, but they may also be caused by volcanic activity and landslides, among others. This event generates waves that propagate from the source, with periods found to range anywhere from a few minutes to over an hour (FEMA, 2005). This study presents the analysis of common two-story structures (focus is on homes) that may be found along the western shores of Puerto Rico, analyzing not only the forces included in present building codes but also the effects of forces produced during a tsunami using the FEMA P-646 guidelines. Per FEMA P-646, Puerto Rico is at a High Hazard of experiencing a tsunami (Table 1.1) therefore it is of the upmost importance to analyze these structures. The structures being analyzed will be typical two-story, reinforced concrete homes, such as those which can be found all along Puerto Rico’s western coasts. Two different models will be analyzed: one that will have load-bearing walls or shear walls on both floors, and the other will be what is known as a “soft-story”, meaning that the first floor does not have walls therefor the dead loads and live loads are supported by columns and beams. These structures will be designed in accordance with the ASCE 7-10 (ASCE, 2010) guidelines for gravitational loads, earthquake loads, and wind loads and be verified using FEMA P-646 (FEMA, 2012). The individual structural elements, such as beams, columns and floor slab will be designed using ACI 318-08 (ACI, 2008) guidelines. Upon completion of the analysis, it is expected to be able to determine whether these structures can withstand the forces associated with such events. en_US
dc.description.abstract Los tsunamis son un raro pero poderoso acontecimiento oceánico que consiste en una serie de olas muy largas causadas por una perturbación a gran escala de un cuerpo de agua, generalmente por terremotos. Las olas se propagan a lo largo de grandes cuerpos de agua; incluso son capaces de cruzar océanos. La principal causa de los tsunamis son los terremotos por debajo, o cerca del fondo del océano, pero también pueden ser causados por la actividad volcánica y los deslizamientos de tierra, entre otros. Este evento genera ondas que se propagan desde el origen, con períodos que varían desde unos minutos hasta más de una hora (FEMA, 2005). Este informe tiene la intención de analizar las estructuras en zancos, comunes en todas partes de Puerto Rico, considerando no sólo las fuerzas incluidas en los códigos de construcción actuales, sino también los efectos de las fuerzas producidas durante un tsunami utilizando las directrices FEMA P-646. Según FEMA P-646, Puerto Rico está en un alto riesgo de experimentar un tsunami (Tabla 1.1) por lo tanto es de la máxima importancia analizar estas estructuras. Las estructuras que se analizarán serán casas de hormigón armado de dos pisos, como las que se pueden encontrar a lo largo de las costas occidentales de Puerto Rico. Se analizarán dos modelos diferentes: uno que tendrá paredes de carga o paredes de corte en ambos pisos, y el otro será lo que se conoce como una estructura "soft-story". Estas estructuras generalmente tienen áreas abiertas en los pisos inferiores. Las cargas de los pisos por encima de éste se transmiten al suelo mediante pórticos. O sea, el primer piso o los primeros pisos (común en las zonas montañosas de Puerto Rico). Estas estructuras se diseñarán de acuerdo con las directrices ASCE 7-10 (ASCE, 2010) para cargas gravitacionales, cargas sísmicas y cargas de viento y se verificarán utilizando FEMA P-646 (FEMA, 2012). Los elementos estructurales individuales, como vigas, columnas y losas de suelo se diseñarán utilizando las directrices ACI 318-08 (Comité ACI 318, 2008). Una vez completado el análisis, se analizará la capacidad de estas estructuras de poder soportar las fuerzas asociadas con los tsunamis. en_US
