This research is a complementary study to a recent experimental study on a newly developed seismic isolator called ball rubber bearing (BRB). BRB-type isolators can be easily manufactured similar to the standard elastomeric bridge bearings and can provide significant energy dissipation during an earthquake through friction provided by steel balls inside the cylindrical core. Structural response of BRBs at low temperatures has not been examined in previous research. In this research, behavior of BRBs exposed to different simulated weather conditions is tested under combined axial and cyclic lateral load. Comparison of room temperature and low-temperature test results indicates that the BRB can have slightly increased damping characteristics and horizontal stiffness in cold-weather conditions. This shift in performance has been included in the proposed design recommendations. (C) 2014 American Society of Civil Engineers.

Renovation of a safety-inspection methodology for river bridges Yanmaz, Ali Melih; Caner, Alp (American Society of Civil Engineers (ASCE), 2007-09-21) River bridges and related infrastructural elements need to be monitored and inspected periodically for deterioration and loss of function due to aging, adverse hydraulic conditions, and chemical attacks. Necessary protective works and related actions should then be implemented to increase safety. Types of items to be inspected would be categorized as structural, geotechnical, hydraulic, and structural material conditions. Requirements for periodic inspections and the ways of handling these activities were d...
Seismic behaviour of roller compacted concrete dams under different base treatments Gharibdoust, Ali; ALDEMİR, ALPER; Binici, Barış (Informa UK Limited, 2019-09-09) The effect of base roughness on the seismic behaviour of roller compacted concrete gravity dams were investigated by pseudo-dynamically testing two 1/75 scaled specimens with smooth and rough base treatments. Both specimens were tested under the effect of three different hazard level earthquakes and also a pushover experiment was conducted to obtain the capacity curve of each specimen. The smooth base specimen exhibited significant sliding under the effect of the maximum credible earthquake motion. In contr...
Analytical Investigation of Lateral Strength of Masonry Infilled RC Frames Retrofitted with CFRP Erdem, Ibrahim; Akyüz, Uğurhan (American Society of Civil Engineers (ASCE), 2010-07-01) In this study, two reinforced concrete frames with hollow clay tile masonry infill walls, retrofitted with diagonally applied carbon fiber-reinforced polymer (CFRP), which were tested previously, were analytically investigated. A simple material model for the masonry infill wall strengthened with CFRP is suggested. The lateral strength of each rehabilitated frame was obtained by pushover analysis of four different models using a commercially available finite-element program, and the results were compared wi...
Performance of a precast concrete beam-to-beam connection subject to reversed cyclic loading Korkmaz, HH; Tankut, T (Elsevier BV, 2005-08-01) This study was performed as one phase of an extensive research program focusing on the seismic behaviour of precast connections carried out in Middle East Technical University. The primary objective of the research program was to observe and investigate the seismic behaviour of the connection detail proposed by the collaborating company and the specimens with improved details, in order to develop a 11 moment resisting precast concrete beam-to-beam connection". In this study, six beam-beam connection subasse...
In Situ Lateral Load Testing of a Two-Story Solid Clay Brick Masonry Building ALDEMİR, ALPER; Binici, Barış; Canbay, Erdem; Yakut, Ahmet (American Society of Civil Engineers (ASCE), 2018-10-01) The seismic behavior of unreinforced masonry (URM) structures has usually been investigated by conducting laboratory tests. Such efforts, although useful in order to understand the response of single walls or subassemblages, cannot fully mimic the in situ seismic response of masonry buildings. In this study, in situ lateral load testing of a two-story full-scale URM building was conducted. First, forced vibration tests were performed to determine the vibration frequencies of the building. Afterwards, the bu...
