“…The periods obtained are 0.66 s and 0.59 s for the longitudinal and transverse directions of the brittle model and 0.52 s and 0.42 s for the ductile model, respectively. These vibration periods are consistent with the approximated values obtained using simplified models [53]. Moreover, the global displacement ductility capacity values obtained through pushover analyses are 3.3 and 2.4 for the ductile and brittle models, respectively.…”

Timber structures have gained interest for the construction of mid-rise buildings, but their seismic performance is still a matter under development. In this study, a numerical analysis of the seismic performance of light-frame timber buildings is developed through a highly detailed model using parallel computing tools. All of the lateral-load-resisting system components and connections are modeled. Combinations of lateral load capacity distributions in structures of one, three, and five stories are studied in order to assess the effects on the global performance of different triggered failure modes through nonlinear static and dynamic analyses. The results suggest that shear bracket connections and sheathing-to-framing connections control the buildings’ responses, as well as the failure mode. For a ductile response, the lateral displacement must be dominated by the in-plane wall distortion (racking); therefore, the system must be provided with a story shear sliding stiffness and load capacity at least twice that of the walls. Furthermore, based on the pushover capacity curves, the performance limits are proposed by evaluating the stiffness degradation. Finally, the effect of the mobilized failure mode on the structural fragility is analyzed. Even though standard desktop PCs are used in this research, significant reductions in the computation effort are achieved.

Introduction: Heritage conservation attracts wide attention worldwide. Jordan has many heritage buildings that were preserved, rehabilitated, and adapted to new functions. However, these conservation efforts could not solve the energy consumption problem or maintain the economic and financial balance, thus reducing building efficiency, slowing down the conservation activity, and forcing us to consider new solutions, especially since Jordan has limited energy sources. Integrating smart technologies in historical buildings is widely effective in achieving the sustainability of their historical, symbolic architectural values. Purpose of the study: We aimed to explore the potential integration of smart technologies in cultural and heritage buildings. Methods: We suggested an alternative solution -adopting the smart building concept in the Abu Jaber Museum in Al-Salt (which recently got on the UNESCO World Heritage List since it has more than 1000 heritage buildings), using an automated lighting control system. Approach: We deployed the qualitative method and case study approach to investigate the potential of adopting the smart building concept in the historical building in Al-Salt, Jordan. The study sheds light on the possibilities of utilizing smart technologies in historical buildings in Al-Salt.The findings indicate that smart technologies can offer great opportunity in preserving the architectural heritage and raising the efficiency of heritage buildings. Novelty: The study provides a framework based mainly on automated lighting systems in historical buildings. For the first time, the focus was on historical buildings in Jordan and their performance.

Tras el sismo de Northridge en 1994, mismo que ocasionó daños significativos a las estructuras de madera, la investigación sobre la respuesta sísmica de muros de entramado ligero ha experimentado un notable crecimiento. Este interés se ha extendido más allá de la zona afectada. Autores de países con tradición constructiva en madera han experimentado sobre la geometría de los componentes del muro, la conexión entre el marco y el panel de revestimiento y la implementación de nuevos materiales. En complemento a la parte experimental se han desarrollado modelos numéricos que capturan de forma precisa el comportamiento ante carga sísmica. Este artículo de revisión del estado del arte tiene como objetivo sintetizar las innovaciones y hallazgos encontrados durante la última década, mismos que se detallan en artículos de investigación disponibles en la base de datos ScienceDirect, haciendo de este trabajo una referencia inicial para explorar futuras líneas de investigación en países donde este sistema no ha sido mayormente divulgado. Se ha adoptado la metodología indicada en la declaración PRISMA para dar un adecuado diagnóstico de la información bibliométrica encontrada, adicionalmente se realizaron mapas bibliométricos basados en autores empleando la herramienta VOSviewer. Cabe señalar que en este trabajo se han excluido aspectos de resistencia al fuego u otros factores ambientales. La presentación de los resultados se organiza en función de dos aspectos clave identificados en la literatura: los estudios experimentales y la modelación numérica de muros de entramado ligero.
