Traditional architecture with timber-framed masonry (TFM) system was used in many countries prone to seismic events due its earthquake-resistant performance. In this context, Romanian TFM buildings were constructed by local builders applying non-engineered measures reduce vulnerability. However, the safety assessment of these still presents open issues material modeling, and simulating complex ...

Abstract Existing heritage buildings can be especially vulnerable to earthquakes. They were designed only considering gravity loads and some of them are located in earthquake prone areas, such as the southwestern Iberian Peninsula. Besides, there is a high uncertainty definition their constructive parameters complex geometry. Due that, it paramount develop accurate numerical models obtain relia...

In recent decades, the dual systems of steel moment-resisting frames and RC shear walls have found extensive application as lateral load-resisting systems for high-rise structures in seismically active areas. This paper investigated the effectiveness of tuned mass damper (TMD), viscous damper, friction damper, and the lead-core rubber bearing in controlling the damage and seismic response of hi...

This paper investigates the applicabilty of an innovative bracing, called Articulated Quadrilateral (AQ) bracing system, which uses shape memory alloys (SMAs), for retroffiting low-rise to high-rise vulnerable SMFRs against strong ground motions. The paper investigates brace fundamental engineering characteristics, design of the system and also configuration of the brace (the proportion of SMA ...

This paper evaluates the potential of novel steel column bases to reduce residual drift risk buildings located at near-fault regions when installed post-tensioned self-centering moment-resisting frames (SC-MRFs). To this end, a prototype building is designed that consists either conventional (MRFs) or SC-MRFs equipped with base (SC-MRF-CBs). The MRFs and are used as benchmark frames. modelled i...

Precast post-tensioned segmental (PPS) bridge piers mitigate global and local damages of structures through natural hinges (joints between their segments) rocking motion segments. The application the PPS is currently growing in Accelerated Bridge Construction (ABC) where segments are manufactured offsite with higher quality, assembled onsite a short time. Structural vulnerability analysis very ...

In the last few decades, structural health monitoring has gained relevance in context of civil engineering, and much effort been made to automate process data acquisition analysis through use data-driven methods. Currently, main issues arising automated processing regard establishment a robust approach that covers all intermediate steps from output production interpretation. To overcome this li...

Abstract A major cause of local to total damages is related structural pounding in a large number past earthquakes. In general, these collisions take place as result differences the dynamic characteristics colliding structures. To acquire better perception behavior structures, this paper, three structures featuring different heights are modeled series and with various configurations next each o...
