Introduction
Diego's current work's subjects are focus on hazard, vulnerability, and seismic risk. The Earthquake Engineering Laboratory of the University of Costa Rica conducts research that involves the use of accelerograms both in defining the ground motion effects and its interaction with structures. In addition, the study of reinforced masonry structures is one of the main topics in the area of ​​vulnerability, also applying a probabilistic approach in much of its research.

Article
Full-text available
Recently proposed capacity-based damage indices and parametric models for capacity curves are applied to frame steel buildings located in soft soils of the Mexico City. To do that, the seismic performance of 2D models of low-, mid- and high-rise buildings is assessed. Deterministic and probabilistic nonlinear static and incremental dynamic analyses...
Article
Most of buildings and structures are usually projected according to two main axes. However, the geographical position of these buildings varies randomly. Such random distributions of the azimuthal positions of structures, in most of the cities, generally, are not accounted for when assessing their seismic risk; certainly, the direction of the seism...
Article
In this article, we present a strong‐motion database from earthquakes recorded by the Earthquake Engineering Laboratory at the University of Costa Rica. The database consists of 2471 three‐component accelerograms from 155 digitally recorded events. It covers the last 20 yr of measurements, including records from the 5 September 2012 Mw 7.6 Nicoya e...
Article
In Costa Rica, typical dwelling constructions are generally built with reinforced concrete masonry walls. This construction practice became one of the most common during the second half of the last century in Costa Rica. These kinds of structures exhibit high lateral stiffness and shear capacity, which makes them susceptible to semi-ductile failure...
Article
This article presents the experimental results and analysis of five full-scale walls subjected to in-plane reversed cyclic displacements. All walls were constructed with reinforcement in both vertical and horizontal directions and, with a reinforced concrete frame in the perimeter of the wall as confinement. This research focuses on the effect of d...

The present work shows the implementation of a data collection strategy for characterizing large amounts of buildings efficiently by the conduction of remote surveys on 360° panoramic images and aerial photographs. A set of 7,296 buildings from the Latin American city of San José, Costa Rica were studied and characterized from a structural engineer...

The selection of the Ground Motion Prediction Models (GMPM) is a key task for any seismic hazard analysis. The Interface and Intraslab subduction zones of Costa Rica are considered in this research. For the first time, a database with more than 1700 strong ground motion records, exclusively from Costa Rica, is used to check the model-data fitting....

In this paper, the soil profile of the Costa Rican Strong-Motion Network (CRSMN) stations is classified based on actual measurements and seismic regulations. The soil classification of the Costa Rican Seismic Code based on the average shear-wave velocity of the top 30 m (VS30) is used as a reference. The site fundamental period (Tf) is included as...

El 22 de abril de 1991, un terremoto de magnitud 7.7Mw generó una gran cantidad de daños en estructuras ubicadas en la zona caribe de Costa Rica. El seguimiento de las normas de diseño sismorresistente disponibles a esa fecha (CSCR 1986), así como las recomendaciones dadas en la normativa actual (CSCR 2010/2014), son empleadas para valorar los daño...

The Earthquake Engineering Laboratory of the University of Costa Rica (LIS-UCR) operates the Costa Rican Strong Motion Database (CRSMDB) and the Costa Rican Accelerographic Network (CRAN). The CRAN started in 1983, and ever since, it has recorded several hundreds of strong motion records that integrate the CRSMDB. The CRSMDB is thus made up of both...

In the present study, a calculation of the relationship between the effective peak acceleration (a_ef) and the peak ground acceleration (PGA) is made. The database of accelerographic records of the Earthquake Engineering Laboratory of the University of Costa Rica, with events recorded between 1983 and 2019 was used. Five specific cases are analyzed...
Article
Directionality effects on the expected strong ground motion in Italy are investigated. After a brief description of the directionality effect and the intensity measures involved, a wide Italian database of strong ground motion records is used, with a total of 949 horizontal accelerograms (two components). The analysis is performed for 5% damped res...

Structures with high lateral stiffness and/or with brittle to semi-brittle elements in their lateral resistant system may exhibit a rapid decrease of their shear capacity and a sudden loss of stiffness when lateral cyclic loads, as those produced by earthquakes, are applied. This behavior can be related to damage (partial or complete) of a particul...

In this paper, the directionality effects of the as recorded ground motions are investigated. The Italian accelerometric archive (ITACA) is used for this purpose. A number of 949 horizontal ground motion records (two components) are used. The following measures, resulting from different ways of combining the maximum values (m1,m2) of the two horizo...

Las estructuras que emplean paredes de mampostería se caracterizan por tener una gran rigidez y capacidad ante cargas paralelas a su plano debido, principalmente, a la gran inercia de algunos elementos que la componen. Bajo condiciones usuales, se dice que los elementos de mampostería, con o sin refuerzo, poseen un comportamiento frágil ante cargas...
Article
Non-linear dynamic analysis and the damage index of Park-Ang have been often used to assess expected seismic damage to a structure. Depending on the size of the structure and the duration of the record, the computational effort in dynamic analyses is usually high. In this research, a new damage index is proposed based on nonlinear static analysis....

The probabilistic analysis of the seismic performance of a structure requires quantifying the uncertainties of the involved variables and parameters, including the seismic action and mechanical properties of its elements. In this article, the seismic performance of high-rise, mid-rise and low-rise of steel buildings, subjected to long duration seis...

Ground Motion Prediction Equations commonly use response spectra as input data. However, the selection of a unique spectral function which minimizes the error between predicted and observed values, remains a subject of research. Recently, response spectra independent of the sensors orientation have been used in seismic hazard studies, showing a red...

The assessment of damage caused by earthquakes in structures, requires the use of nonlinear analysis, either static or dynamic, in order to define the performance of the buildings for the considered hazard levels. In this paper, different damage models based on static and dynamic nonlinear analysis are used in the evaluation of a low-rise building...

Full-text available
In this research the influence of the directionality of the recorder instruments on the estimation of the maximum ground motions is analyzed; that means that the geometric mean as a measure of ground motion intensity for the same earthquake, depends on the orientation of the recording sensors. A procedure recently developed allowing to take into ac...

The seismic intensity measures based on acceleration, are used to define attenuation laws and in seismic hazard analysis. Usually, these measures are defined in terms of the acceleration response spectra of two horizontal accelerograms, performing different combinations of the spectral components, although the geometric mean is the most commonly us...
