Based on substantial sets of data, the damage ratios for both buildings and contents were found to fit well to the lognormal distribution.…”

SUMMARYThis paper describes an analysis of damage costs to hause and farm property in the M, = 6.6 Edgecumbe, New Zealand earthquake of 2 March 1987. The study investigated damage ratios for dwellings, their contents and domestic motor vehicles. The damage costs were converted to damage ratios by dividing them by the total value of the relevant property in the intensity zones concerned. The mean values and statistical distributions of these damage ratios were then found, the lognormal distribution fitting very well.The mean damage ratio for house buildings at MM intensity IX was 0.080 and the mean damage ratios were generally smaller than previous studies had shown. The mean damage ratios were similar for buildings and contents from MM6 to MM9, but there was no correlation between building and contents damage on an individual basis.

Identificación de procesos patológicos más frecuentes en fachadas y cubiertas en España a partir del método Delphi. Informes de la Construcción, 67(537) RESUMENLos métodos basados en factores de durabilidad, según ISO-15686, son una forma eficiente de estimar la vida útil los elementos de un edificio. Sin embargo, se ha constatado la escasa información sobre cuantificación de dichos factores y sobre su vinculación con la vulnerabilidad o procesos de deterioro que podría presentar un elemento constructivo. En consecuencia, este artículo describe un procedimiento para caracterizar los mecanismos de daño más frecuentes en la envolvente del edificio, por ser un elemento con un elevado riesgo de presentar lesiones y ver reducida su durabilidad. Para elaborar dicha información se ha utilizado el método Delphi que implica la consulta a grupos de expertos a fin de generar convergencia de opiniones. Los resultados obtenidos permiten la identificación y cuantificación de los factores de durabilidad relevantes que condicionan la aparición de un daño de un elemento y afectan a su vida útil.

Abstract. "How do environmental risk systems function?" is the main underlying question to be answered by students learning environmental risk. Under the framework of the Innovative Teaching project, an open-source, interactive and collaborative web-GIS application (RISKGIS) is developed for students in learning and understanding of environmental risk systems with a focus on geohazards and risk. The aim is for students to better understand and become familiarized with 10 approaches used by experts as well as for teachers to better evaluate and monitor student learning, through a practical application with real case studies and hand-on exercises. To identify the possibility and applicability of the developed learning platform, a series of practical exercises is carried out with undergraduate and postgraduate students during the spring and autumn semesters of the environmental risk, and advanced risk and vulnerability courses of the University of Lausanne. A total of three exercises are conducted starting from the rapid risk calculation (individual) exercise to more 15 complex risk management (individual and group) exercise with different case studies and functionalities of the learning platform. Depending on the exercises, students are asked to answer the test quiz, feedback questionnaires and group reports (if requested) through the Moodle platform to evaluate the performance of the students, exercises and the RISKGIS platform.Average feedback results from three different exercises revealed that students found the exercises useful and interesting, while a user satisfaction score of 7/10 and a system usability scale (SUS) of 64/100 is achieved, showing that several aspects 20 of the RISKGIS learning platform could be further improved with suggestions and feedback of the students.
