Structural modelling, analysis, and evaluation of the historic buzlupinar bridge and recommendations for its reconstruction /

Çabuk, Ezgi
The Historic Buzlupınar Bridge is a timber pedestrian bridge, located in Buzlupınar Village, Rize, Turkey, which was constructed early in the 20th century and partially collapsed in 2008 at about 100 years of age. The wind loading was deemed responsible for the collapse of the bridge as stated by the locals. General Directorate of Highways has attributed special attention to Buzlupınar Bridge due to its rare value as a timber pedestrian bridge and has taken decision in 2012 to be rebuilt it again. In this thesis, the original architectural and structural characteristics of the bridge were studied as well as its current condition and interaction with the environment. Structural analysis and evaluation of the bridge was carried out both with hand calculations and Finite Element Model to investigate its structural behaviour under live loads, wind loads, and earthquake loads. The FEM was formed with SAP2000 using frame, shell, and solid elements. The critical failure modes for overturning of the bridge were checked. Material tests were done on new timber members for the reconstruction studies to determine the mechanical properties of the timber elements. Controlled shear and tension tests were carried out using nailed connections which will be used in the reconstruction project. Structural proposals were made for the reconstruction project considering the original structural and architectural features of the bridge. Furthermore, stabilization, monitoring, and maintenance recommendations were made, which would be helpful to prolong the service life of the structure. The investigation and reconstruction studies of the bridge are conducted by the General Directorate of Highways. The measured surveys, documentation of the bridge and reconstruction projects were made by Mukaddes Ataman (Bender Restoration). The proposals and recommendations made within the scope of this thesis might be helpful for the reconstruction project; however, provided as-is and does not burden the liability of structural design or restoration work.


Causes and effects of urban transformation processes on the cultural heritage in Hacı Bayram area, Ulus /
Demiröz, Merve; Şahin Güçhan, Neriman; Conservation of Cultural Heritage in Department of Architecture (2015)
Hacı Bayram Area is located on the top ofa small hill on the north-westenı part of the Ankara Citadel in Ulus Historic Center. Co-existance of the Temple of Augus­ tus and Hacı Bayram Veli Mosque as a symbol of spatial continuity throughout the history and surrounding traditional neighbourhoods give the area its unique charac­ teristics. The Hacı Bayram Square and surrounding environment, which is called as Hacı Bayram Area throughout the history, has always became one of the focal points of huge interventi...
Structural monitoring of andirap bridge for overload passage
Türer, Ahmet (2009-01-01)
Andirap bridge is located over Seyhan river passing a deep valley and has a big strategic importance since heavy loaded trucks carrying excavation and fill material from Kavsak Bendi hydroelectric power plant construction site have to use the bridge. Serious concerns were raised since Andirap bridge may not be adequately strong to carry about 250 trucks per day, each weighting more than 50 tons for the coming next two years. A preliminary visual and analytical evaluation of the bridge has leaded instrumente...
Seismic evaluation and strengthening of nemrut monuments
Aktas, Yasemin Didem; Türer, Ahmet (2015-05-01)
Nemrut Dag Tumulus and Monuments, constructed during the Commagenian Kingdom approximately 2000 years ago on the peak of Mount Nemrut, is a UNESCO World Heritage Site in Turkey. The region is about 5 km away from the East Anatolian Fault, therefore, this paper focuses on dynamic testing and earthquake simulations carried out within the framework of the Commagene Nemrut Conservation Development Program in order to explain monuments' current condition. The simulations showed vulnerability of cut-stone blocks ...
Improvement of computational software for composite curved bridge analysis
Kalaycı, Ahmet Serhat; Topkaya, Cem; Department of Civil Engineering (2005)
In highway bridge construction, composite curved girder bridges are becoming more popular recently. Reduced construction time, long span coverage, economics and aesthetics make them more popular than the other structural systems. Although there exist some methods for the analysis of such systems, each have shortcomings. The use of Finite Element Method (FEM) among these methods is limited except in the academic environments. The use of commercial FEM software packages in the analysis of such systems is cumb...
Local scour characteristics around semi-circular end bridge abutments with and without collars
Tekin, Fatime; Köken, Mete; Department of Civil Engineering (2012)
The major damage to bridges occurs due to scour of the bed materials around piers and abutments during severe floods. This study involves the experimental investigations of the various scour patterns forming around abutment models tested with and without collars as scour countermeasures. The experiments were conducted in a rectangular channel under clear-water scour conditions. In the first part of this study, 34 experiments were conducted with semi-circular end abutment models with and without a collar for...
