El lote donde se construirá el edificio tiene un área total de 1,350 m2. El edificio consta de 22 departamentos, 2 en el primer piso y 4 en cada piso restante; además de 44 estacionamientos distribuidos en el sótano y en una playa de estacionamiento, ubicada en la parte trasera del primer piso. El suministro de agua se realizará mediante un sistema de cisterna y bomba hidroneumática, sin tanque elevado. La cisterna se ubica en el sótano del edificio.

El lote donde se construira el edificio tiene un area total de 1,350 m2. El edificio consta de 22 departamentos, 2 en el primer piso y 4 en cada piso restante; ademas de 44 estacionamientos distribuidos en el sotano y en una playa de estacionamiento, ubicada en la parte trasera del primer piso. El suministro de agua se realizara mediante un sistema de cisterna y bomba hidroneumatica, sin tanque elevado. La cisterna se ubica en el sotano del edificio. La profundidad de cimentacion es variable, teniendo una profundidad maxima de -3.20 m. El suelo donde se cimentara la estructura tiene una capacidad admisible de 4 kg/cm2. El sostenimiento de taludes se realizara mediante calzaduras temporales de concreto ciclopeo. El sistema estructural del edificio esta conformado por placas (muros de corte), columnas y vigas. Para los techos se usaron losas aligeradas armadas en un sentido y losas macizas armadas en dos sentidos, las cuales ademas funcionan como diafragmas rigidos en cada piso del edificio. La cimentacion esta conformada por zapatas aisladas, zapatas combinadas y cimientos corridos. Tanto el analisis como el diseno estructural se desarrollaron dentro del marco normativo del Reglamento Nacional de Edificaciones (RNE), y las Normas que lo componen. Se realizo el analisis sismico para comprobar que el sistema sismorresistente del edificio cumpla con los requisitos especificados en la Norma E.030 del RNE, ademas se obtuvo las cargas sismicas en cada elemento. El modelo sismico se analizo con la asistencia de un computador, mediante el programa ETABS. Se analizaron las cargas de gravedad realizando el metrado de cargas para cada elemento y asignando dichas cargas al modelo estructural correspondiente. Las losas macizas y las zapatas combinadas se modelaron usando el metodo de elementos finitos FEM, con la asistencia del programa SAP2000. El diseno en concreto armado se realizo cumpliendo con lo especificado en la Norma E.060 del RNE, la cual se basa en el metodo de diseno LRFD (Load and Resistance Factor Design).

Case studies of multihazard damage: Investigation of the interaction of Hurricane Maria and the January 2020 earthquake sequence in Puerto Rico

It aims to discuss the potential interactions of Hurricane Maria and 2020 earthquake series and the considerations they underscore for future field reconnaissance missions. Traditionally, post-disaster damage assessment activities focus on one hazard and overlook the potentially cascading effects of multiple hazards on structures and infrastructure. This paper provides case studies showing the possible interaction of multiple hazards and their cascading effects observed in Puerto Rico. Infrastructure surveyed includes port facilities, buildings (particularly historical structures), and bridge structures. The data collected during the reconnaissance missions reveal how the impacts of Hurricane Maria, along with infrastructure aging and delayed repair and recovery activities, may have influenced the damage level and failure modes observed during the earthquake sequence a few years after. These case studies illustrate the nature of multihazard interactions and how these effects should be documented during post-disaster assessments. Beyond the insights gained from the case studies illustrated in this paper, the field survey instrument is provided as a basis for future reconnaissance studies, and the full set of reconnaissance data collected are published on the NSF funded NHERI DesignSafe cyberinfrastructure. As a result, this work not only provides data from Puerto Rico that can inform future damage and recovery modeling efforts, but also offers survey instruments and a field data collection process that is particularly tailored to cases where multihazard effects are at play.

Effectiveness of Rubber Isolators for the Seismic Retrofitting of a Peruvian Highway Concrete Bridge

The Huamani Bridge is analysed as a case study. Located on the central coast of Peru, this bridge was constructed around 1950 with obsolete seismic provisions, using fixed steel bearings. It suffered from severe damage during the 2007 Pisco Earthquake (8.0 Mw). As-built and isolated models were analysed and their results were compared. For the isolated option, the fixed steel bearings are to be replaced with Lead Rubber Bearings (LRB), in order to uncouple the movement of the super and sub-structure, thus increasing the flexibility of the system and decreasing the forces transmitted to the lateral stability elements (piers and transverse beams). Flexible links having the isolators' properties were introduced into the as-built model. The analysis of the isolated model was performed following the AASHTO GSID Simplified Method. It was found that implementing the isolation system increased the structure's overall damping ratio by more than 3 times, as well as its flexibility. This effectively reduced the solicitations in the sub-structure and transverse beams by an average of 75%. It is concluded that the use of rubber isolators is effective for retrofitting highway concrete bridges and that this analytical procedure can be applied to other bridges of similar characteristics in Peru.

Data collection of damage to Puerto Rico's infrastructure due to Hurricane Maria and the 2019-2020 earthquakes

The first event was Hurricane Maria in 2017, and the second was a series of earthquakes that occurred in late 2019 and early 2020. The focus of the data collection remained on regions, structures, and elements that experienced the impacts of both events. Therefore, the focus of the reconnaissance was on the south side of the island. The data collection methods included a damage assessment survey, multiple image types, UAS image and video, and Lidar scan data.
