The precast segmental bridge has the advantages of fast construction speed, good economic performance, and small impact on surrounding environment. In order to study role temporary pre-stressing system in cantilever assembly process segment box girder bridge, ABAQUS was used simulate standard section a viaduct. Studying compressive stress relative sliding joint under action self-weight pre-stre...

For creep and shrinkage investigations, relatively small cylindrical specimens are generally exposed to constant climatic conditions. The derived mainly empirical prediction models used for the calculation of large engineering structures with massive cross-sections. In this paper, expected values material according fib Model Code 2010 Eurocode 2 compared monitoring data, which were acquired ove...

The hinge joints of the assembled concrete multi-girder bridge (ACMGB) are main components transverse transmission loads and decline their capacity would lead to degradation cooperative working performance (TCWP) multi-beam system. As key this kind bridges, its severe result in single-girder-bearing phenomenon inducing collapse. In order detect TCWP timely, paper proposes a vibration-based moni...

Abstract. Temporal analysis of deformations Time Series (TS) provides detailed information various natural and humanmade displacements. Interferometric Synthetic Aperture Radar (InSAR) generates millimetre-scale products, indicating the chronicle behaviour detected targets via TS products. Deep Learning (DL) can handle a massive load InSAR to categorize significant movements from non-moving tar...

This research proposes an approach for vision-based autonomous navigation planning of unmanned aerial vehicles the collection images suitable rapid post-earthquake inspection reinforced concrete railway viaducts. The proposed automatically recognizes and localizes critical structural components, columns in this case, determines appropriate viewpoints relative to identified components. Structura...

Relatively little is known about the genetic diversity of the Philippine population, and this is an important gap in our understanding of Southeast Asian and Oceanic prehistory. Here we describe mitochondrial DNA (mtDNA) variation in 423 Philippine samples and analyze them in the context of the genetic diversity of other Southeast Asian populations. The majority of Philippine mtDNA types are sh...

Acoustic emission (AE) technique is gaining increasing interest for application in civil engineering. AE indeed is a passive non intrusive technique that can be applicable either in Structural Health Monitoring SHM (global evaluation) and in defect localization (local evaluation). However a great effort yet have to be done on data handling and data interpretation, especially in eliminating acou...
