A novel method is presented for the determination of ultimate capacity masonry solid shear walls based on simple models resulting from equilibrium considerations. Some basic principles determining acceptability are firstly stated. Based these rules, specific proposed subjected to either distributed or concentrated loading. The performance and their applicability estimation shown by comparison with experimental results advanced numerical simulation.
To monitor the structural health of a bridge over its lifetime is necessary to have numerical models to, based on changes in response it, detect possible damage. For this reason and deepen understanding behavior bridges local roads Department Santander, research group materials structures -INME - UIS, takes series post-tensioned concrete that were be flooded by impounding reservoir Hidrosogamoso, becoming full-scale laboratory. Among these El Ramo bridge, which beam slab type, comprising...
The Latin American Giant Observatory (LAGO) is an extended cosmic ray observatory composed by a network of water-Cherenkov detectors spanning over different sites located at significantly altitudes (from sea level up to more than $5000$\,m a.s.l.) and latitudes across America, covering huge range geomagnetic rigidity cut-offs atmospheric absorption/reaction levels. This detection designed measure the temporal evolution radiation flux ground with extreme detail. LAGO project mainly oriented...
Introduction: The construction of long-span bridges, especially box girder type, has been increasing in recent years Colombia. Due to the importance that these structures represent for infrastructure country, there is a need monitor their structural integrity analyze behavior throughout life cycle, detect changes caused by possible damages and establish maintenance plans. This monitoring can be carried out through characterization dynamic properties structure. Objective: study shows results...
In-service prestressed concrete box girder bridges have received increasing attention in recent years due to a large number of reaching decades service. Therefore, the ageing infrastructure demands development robust condition assessment methodologies based on affordable technology such as vehicle-induced vibration tests (VITs) contrast with more expensive existing technologies using hammers or shakers. Ambient (AVTs) been widely used worldwide, taking advantage freely available ambient...
Un gran número de edificaciones educativas universidades públicas colombianas requieren con urgencia intervenciones reforzamiento estructural. Sin embargo, por las consideraciones urbanismo la mayoría ciudadelas universitarias, estas se encuentran separadas entre sí zonas verdes y estructuras acceso, donde últimas caracterizan generalmente falta información en sus condiciones contorno propiedades los materiales, el agravanteque muchos casos conectadas estructuralmente educativas.

During the last few decades, several advantages of concrete wall housing have been identified when compared with masonry houses located in high hazard seismic zones; for instance, higher lateral stiffness and strength, ductility capacity. Therefore, construction lowrise units using reinforced shear walls has become a preferred choice consequently, its use increased considerably many Latin American countries. The aim this study is to experimentally assess strains on steel reinforcement...

This paper presents a comparative study of an Optimal Sensor Placement (OSP) implementation conducted in box girder bridge using experimental and numerical mode shapes obtained at different construction stages. It is widely recognized that monitoring the dynamic response bridges during stages provides valuable information to adjust design considerations. Therefore, there need for development OSP implementations order find optimal number sensors needed real applications. In present study, OPS...
<p>The use of prestressed concrete (PSC) box girder bridges built by segmentally balanced cast-in-place cantilevers has spread massively due to noticeable advantages over traditional. However, excessive deflections have been observed in 10-years old constructed worldwide which designed based on international code standards that underestimated rheological effects. To guarantee 100-year design life bridges, it is necessary a periodic monitoring system validates in-service performance. In...
The balanced cast-in-place cantilever erection method has become a popular construction bridge technique. main advantages include an industrialized technique that prevents the use of intermediate supports and rapid construction. However, long-term response this typology is not well understood as deflections due to time-dependent phenomena (such creep shrinkage) are significantly simplified in design codes. Existing prediction models commonly used tend underestimate deflections, result, field...
Abstract In oil wells with beam pumping systems, sucker rods mainly failed by fatigue due to the fact that they operate under cycling tension stresses. Additionally, superficial defects could be generated during handling and operation of rods, which favor formation cracks consequently decreasing original expected life rod. Because a high rate rod failures fatigue, consequent increase in operational costs, study was done obtain experimental data will used for selection design strings. Fatigue...
The use of prestressed concrete box girder bridges built by segmentally balanced cantilevers has bloomed in the last decades due to its significant structural and construction advantages complex topographies. In Colombia, this typology is most common solution for structures with spans ranging 80-200 m. Despite popularity, excessive deflections worldwide evidenced that time-dependent effects were underestimated. This problem led constant updating creep shrinkage models international code...
