Block type quay walls are one of the most generally used type of gravity quay walls however seismic risks of this kind of structures have not already received the proper amount of attention. In this study, stability of block type quay wall which consists of two concrete blocks is investigated experimentally and numerically. 1 g shaking table tests are used for experimental study. Model scale is 1/10 and model is placed on rigid bed to ignore damage due to foundation deformation. Two different granular materials (Soil 1 and Soil 2) which have different nominal diameters are used as backfill materials to understand the effect of nominal diameters on structure's stability. During the experiments accelerations, pore pressures, soil pressures and displacements are measured for two blocks under different cycling loadings. Soil pressure test results are presented in non-fluctuating and fluctuating components to determine the distribution and application point of the fluctuating component on two blocks. By using experiment results, the friction coefficients between the rubble-block and block-block are determined and compared with recommended friction coefficients in standards. PLAXIS V8.2 software program is used for numerical study to determine the material properties.

Seismic vulnerability, behavior and design of tunnel form building structures Balkaya, C; Kalkan, E (Elsevier BV, 2004-12-01) Multi-story reinforced concrete tunnel form buildings are one of the common structural types in regions prone to high seismic risk due to the buildings inherent earthquake resistance and ease of construction. Despite their good performance during earthquakes in 1999 in Turkey, and abundance of such structures scattered worldwide, current seismic codes and design provisions provide insufficient guidelines for their seismic design. As a compensatory measure, a series of modal and nonlinear static analyses are...
Seismic behavior of autoclaved aerated concrete low rise buildings with reinforced wall panels Gökmen, Furkan; Binici, Barış; Canbay, Erdem (Springer Science and Business Media LLC, 2019-07-01) Reinforced Autoclaved Aerated Concrete (AAC) wall panels are more commonly used to construct load-bearing walls in low-rise prefabricated buildings located in seismic zones. In the scope of this study, the seismic response of buildings constructed with reinforced AAC wall panels was investigated. To this end, an in situ test was conducted on a two-story test building under reversed cyclic displacement excursions. It was determined that the test building could carry a lateral load of 60% more than its weight...
Cyclic Testing of Reinforced Concrete Double Walls ALDEMİR, ALPER; Binici, Barış; Canbay, Erdem (2017-03-01) Reinforced concrete double walls are semi-precast structural elements constructed with factory-produced concrete shells on two exterior sides and cast-in-place concrete in the middle of the section. Their use has been limited in seismic zones due to the difficulty of connecting the adjacent double walls for monolithic action, and providing suitable seismic details in the presence of the lattice girder that is used to hold the concrete shells together. These limitations were overcome with the invention of di...
Nonlinear analysis of RC frames retrofitted with structural steel elements Akpınar, Uğur; Binici, Barış; Department of Civil Engineering (2010) Deficient concrete structures are serious danger in seismic zones. In order to minimize economical and human loss, these structures should be retrofitted. Selecting suitable retrofitting schemes requires detailed investigation of these systems. Considering these facts, this study aims to calibrate analytical models of systems with chevron braces and internal steel frames; and evaluate their seismic performances. First, analytical models of the frames with braces and internal steel frames were prepared and t...
Behaviour of AAC infilled RC frames under in plane and out of plane seismic demands Binici, Barış; Aldemir, Alper; Canbay, Erdem; Yakut, Ahmet (2017-11-24) Observations after several earthquakes revealed that infill walls may significantly alter the response of reinforced concrete frame buildings. They increase the lateral stiffness and strength of frames subjected to low to moderate in-plane seismic excitation, however they may experience sudden failure under the combined action of in-and out-of-plane seismic demands. Autoclaved aerated concrete (AAC) is a popular choice of infill wall material due to its advantages such as light weight, good insulation and h...
