Two series of tests were made to study the behavior of jacketed columns. The first series consisted of uniaxially loaded specimens, and the behavior of jacketed columns was compared with a monolithic reference specimen. The main objective of this series was to study the effectiveness of repair and strengthening jackets and the differences between jackets made under load and after unloading. Specimens with repair and strengthening jackets behaved well when jacketing was introduced after unloading. Repair jacketing made wider load exhibited poor behavior In the second series, jacketed columns were tested under combined axial load and bending (monotonic and reversed cyclic). Two monolithic specimens also were tested to serve as reference specimens. Effectiveness of repair and strengthening jackets was studied considering strength, stiffness, and energy dissipation. The influence of load history (monotonic and reversed cyclic) on the behavior of jacketed columns also was studied. Repair and strengthening jackets behaved well both under monotonic and reversed cyclic loadings.

Behavior of steel-concrete partially composite beams with channel type shear connectors Baran, Eray; Topkaya, Cem (2014-06-01) This paper summarizes the findings of an experimental study investigating the flexural behavior of partially composite beams incorporating channel type shear connectors. Results from monotonic load testing of four full-scale steel-concrete composite beams and a steel beam are presented. The main effort focused on identifying the variation of strength and stiffness properties of beams with various degrees of partial composite action. Behavior of channel shear connectors in the composite beam specimens is rel...
Optimum design of reinforced concrete plane frames using harmony search algorithm Akın, Alper; Saka, Mehmet Polat; Department of Engineering Sciences (2010) In this thesis, the optimum design algorithm is presented for reinforced concrete special moment frames. The objective function is considered as the total cost of reinforced concrete frame which includes the cost of concrete, formwork and reinforcing steel bars. The cost of any component is inclusive of material, fabrication and labor. The design variables in beams are selected as the width and the depth of beams in each span, the diameter and the number of longitudinal reinforcement bars along the span and...
Numerical analyses of load tests on model foundations in dry sand Unsever, Y. S.; Matsumoto, T.; Özkan, M. Yener (2015-01-01) In this study, a series of vertical and cyclic horizontal load tests on 3-pile piled raft model were carried out in dry sand to investigate the piled raft behaviour under combined loads. Also, numerical modelling of experiments were carried out by using FEM software, PLAXIS 3D. Hardening soil model was employed to model the sand, and elastic model was used for the pile and the raft. Soil parameters were estimated from consolidated drained triaxial tests carried on the sand samples and pile parameters were e...
Performance of a moment resisting beam-column connection for precast concrete construction Baran, Eray; BARAN, MEHMET; Kurtoglu, Metin; Torra-Bilal, Ines (2021-11-01) Seismic performance of a specific type of moment resisting precast concrete beam-column connection was investigated through reversed cyclic load tests. Structural steel components were incorporated with precast concrete beam and column elements in the experiments to provide a ductile moment resisting connection. Additionally, nonlinear finite element analysis (FEA) of typical monolithic and precast connections was performed to investigate the performance and failure modes of these connections. Concrete Dama...
Reliability-Based Liquefaction Triggering Assessment Framework: A Unified Approach for SPT-CPT-Vs Çetin, Kemal Önder; Ayhan, B. Umut; Moss, Robb; Kayen, Robert (2022-01-01) For longer than four decades, the current practice for liquefaction triggering engineering assessments have been dominated by case history-based deterministic and probabilistic models. The predictive model proposals have been constituted based on different sets of case histories concerning in-situ test indices, namely standard penetration test (SPT) N value, cone penetration test (CPT) q, and shear-wave velocity (V-s), etc. The present study uses the databases of Cetin et al., Moss et al., and Kayen et al. ...
