A challenging prototype building having irregularly placed shear walls in plan has been designed and tested on the AZALEE shaking table at the TAMARIS laboratory in CEA/Saclay. The research project, called ENISTAT, was funded by the SERIES project via Transnational Access to the CEA/Saclay facility in France. The project has three main objectives: (1) Study the behaviour of the mock-up under increasing bi-directional horizontal synthetic earthquake records; (2) Attempt to evaluate the experimental results using modern experimental techniques for data acquisition; (3) Implement & monitor the performance of a new structural element that allows for wall-slab connection to reduce thermal energy losses. Rutherma elements were used only at the second floor level as a connection member between the shear walls and the slab. After initial low level tests, seismic tests having PGA’s of 0.1, 0.2, 0.4, 0.6 and 0.8 g were applied consecutively. During the first three tests, i.e. up to 0.4 g, no significant damage was observed in the structural members except minor hairline cracks on the spandrel beams. At the 0.6 g test, more cracks in beams were observed without any major crack in walls. During the 0.8 g test, separation of the shear wall member from the foundation was observed on the flexible side. No damage on the Rutherma breakers was observed.


Experimental evaluation of the in-plane behaviour of masonry wall infilled RC frames
Suzuki, Tomomi; Choi, Ho; Sanada, Yasushi; Nakano, Yoshiaki; Matsukawa, Kazuto; Paul, Devjyoti; Gulkan, Polat; Binici, Barış (2017-10-01)
This study focuses on the in-plane behaviour of unreinforced masonry (URM) infill walls installed in reinforced concrete (RC) frames. Five 1/4-scale model frames were designed based on a prototype RC building with URM infill walls in Turkey. The experimental parameters were the layout of the URM infill (its presence or absence), number of spans (single or double), number of stories (single or double), and stacking pattern of the URM infill (horizontal or vertical). Static cyclic loading tests were conducted...
Analytical study on seismic retrofitting of reinforced concrete buildings using steel braces with shear link
Durucan, Cengizhan; Dicleli, Murat (2010-10-01)
This paper is focused on a proposed seismic retrofitting system (PRS) configured to upgrade the performance of seismically vulnerable reinforced concrete (RC) buildings. The PRS is composed of a rectangular steel housing frame with chevron braces and a yielding shear link connected between the braces and the frame. The retrofitting system is installed within the bays of an RC building frame to enhance the stiffness, strength and ductility of the structure. The PRS and a conventional retrofitting system usin...
Experimental and numerical analysis of a bolted connection in steel transmission towers
Baran, Eray; Sen, Gokmen; Draisawi, Ammar (2016-06-01)
This paper presents an integrated numerical and experimental study on a bolted splice connection used in main legs of steel lattice transmission towers. At specific locations, where the number of angle sections in built-up cross section of main leg members changes, the complex geometry around the connection region results in eccentricities in the load path and indirect load transfer. Such complex configurations and uncertainties in the load path have led to overdesigned connections with increased number of ...
Experimental analysis of curved laminated beam
Uzhan, Tevfik; Aşık, Mehmet Zülfü; Department of Engineering Sciences (2010)
In this thesis, experimental studies are carried out on curved laminated glass beams to form a database for the scientists who may like to test their mathematical models. Beams which are only free to rotate and constrained in radial direction at both ends are tested to make the data available for further calculations. Test setup is prepared to minimize error that could occur due to test setup and data readings. Material testing machine and 4 channel data collecting machine are used to measure the signals at...
Experimental and numerical analysis of cold-formed steel floor trusses with concrete filled compression chord
GÜLDÜR, HAZAL; Baran, Eray; Topkaya, Cem (2021-05-01)
© 2021 Elsevier LtdFloor trusses fabricated from cold-formed steel (CFS) sections offer several advantages over more conventional floor systems. The current paper reports the findings of an integrated experimental and numerical study focusing on the behavior of CFS floor trusses made of lipped channel sections with the compression chord member filled with concrete. This type of configuration occurs when CFS trusses are used together with a cast-in-place concrete slab. The experimental part of the study incl...
