Aging highway infrastructure requires effective rating methodologies to prioritize bridges for rehabilitation and repair. To aid engineers in decision making regarding bridge maintenance, a three-dimensional 3D visualization system is developed for rating reinforced concrete deck-girder bridge. Color codings show the most probable mode of failure for girder cross sections under combined moment-...

The role of abutments on the seismic vulnerability bridges has been relatively little studied in geotechnical literature. To cover this gap, 3D numerical simulations were herein performed, by studying performance three single-span bridge configurations. models used OpenSees to account effects due soil structure interaction between deck and abutments. In particular, advanced materials implemente...

Bu çalışmada, Deprem Bölgelerinde Yapılacak Binalar Hakkında Yönetmelik 2007 (DBYBHY-2007) ve Türkiye Bina Yönetmeliği 2018 (TBDY-2018) esaslarına göre tasarlanmış 3, 6 9 katlı toplam altı adet ters-V parçalı-X tipi merkezi çaprazlı çelik çerçevelerin (MÇÇÇ’lerin) dinamik performansları karşılaştırılmıştır. DBYBHY-2007 TBDY-2018’de tanımlanan 50 yılda aşılma olasılığı %2 olan en büyük deprem ye...

Original scientific paper Based on the experimental research on three cross-shaped columns with 500 MPa grade reinforcing steel bars, the contrastive analysis is made on failure mode, bearing capacity and displacement ductility of each column specimens with different stirrup spacing under the identical axial compression ratio. The research shows that the longitudinal bars yield before spalling ...

In recent years, the structural engineering community has been actively exploring the use of wireless sensors in structural monitoring systems. A direct result of low-cost wireless sensors is wireless monitoring systems defined by high nodal densities offering extensive sets of structural response data. Such data sets can serve as a powerful tool for validation of structural design assumptions ...
