“…Methods using seismic noise have been broadly used in the past decades for soil‐structure interaction investigation (Guéguen et al, 2007; Hinzen et al, 2004; Paudyal et al, 2012), risk assessment (Bhandary et al, 2014), landslide characterization (Méric et al, 2007), building assessment (e.g. Guillier et al, 2014) and even for the exploration of Mars (Knapmeyer‐Endrun et al, 2017). The HVSR method consists of using the seismic ambient noise vibrations (Stehly et al, 2006) recorded at a single station, from which the ratio between the Fourier amplitude spectra of the horizontal (averaging NS and EW components) to vertical components are estimated.…”

Active tectonics necessitate to select key zones for detailed studies. In the Himalaya, and specially in its piedmont, the quality of natural outcrops is poor due to strong weathering, heavy vegetation and/or anthropogenic influence. In this paper, we show that the HVSR (Horizontal-to-Vertical Spectral Ratio) method allows exploring the structures beneath the 2-Active tectonics in the Darjeeling piedmont Terra Nova plain south of the Himalayan mountain front. This method is easy to apply in any context and we show that it has allowed revealing the subsurface structures down to 600 meters even in jungle areas. We have correlated geomorphologic scarps evidenced by geomorphologic profiles but nearly invisible in the jungle, to thrust structures evidenced at depth. Two of these scarps of about ten meters affect the 3.7 ± 0.7 ka old surface and imply that about half of the convergence is expressed south of the Himalayan front in this zone.

En la presente investigación se validó estructuralmente una vivienda de interés social, la cual posee un sistema constructivo innovador de paneles tipo sándwich. Para validar la vivienda se realizaron varios estudios experimentales que incluyen pruebas de campo y ensayos de laboratorio, tanto en los materiales como en el prototipo de vivienda. Para los ensayos se utilizaron las normas ASTM y el código ACI-318, bajo la dirección técnica del Centro de Investigación de la Vivienda de la Escuela Politécnica Nacional. De los estudios realizados se obtuvieron curvas de capacidad, rigidez, esfuerzos y módulos de elasticidad de los materiales, evidenciando que la vivienda presenta un buen comportamiento ante cargas verticales y laterales (acciones sísmicas). Adicionalmente se realizó un estudio analítico con la ayuda de un modelo matemático tridimensional para conocer la distribución de esfuerzos en la vivienda y compararlos con los esfuerzos obtenidos experimentalmente. Los resultados obtenidos mostraron que la vivienda es apta para resistir solicitaciones gravitacionales y laterales que requiere la norma NEC-15.

“…One of the dynamic parameters that has been widely studied worldwide due to its great importance is the vibration period, which is directly related to the stiffness of the building and can be associated with external inputs (acceleration, soil response, materials, construction quality, etc.). [5] The vibration period is usually obtained analytically, performing the modelling in a structural calculation software, which in some cases this value ends up being a period far from reality because it does not consider the interaction between the structure and the nonstructural elements (masonry) and the soil-structure interaction. [6] .…”

In the Faculty of Dentistry of the Catholic University of Cuenca, located in the city of Cuenca, province of Azuay. The lecture hall and the clinics of the faculty are built. These structures were built during 2018 and 2019. Due to the seismic events occurred in recent years, monitoring was carried out to obtain the characterization of the dynamic behaviour. The two structures are formed by a structural system based on structural steel frames (beam-column), the structure for laboratory use has metal columns filled with concrete, while the structure for classroom use has metal columns without concrete filling. The main objective was to obtain the vibration periods experimentally from the recording of environmental vibrations and also to obtain them analytically with mathematical models elaborated in structural analysis programs and environmental vibration tests were performed. The results show that building 1, composed by the dentistry clinic, obtained a vibration period of 0.41 s in X and 0.33 s in Y (Analytical Model); and, in the environmental vibration test it showed a period of 0.46 s in X and, 0.30 in Y. Building 2, composed of the dental faculty classroom, obtained periods of 0.53 s in X and 0.29 s in Y (Analytical Model). While in the environmental vibration studies they gave values of 0.52 s in X and 0.26 in Y.
