Abstract

In the three-dimensional laboratory experiments of reinforced concrete systems, procedures of the applying loads are very important to achieve of actual building behavior. In this study, it was aimed to reveal the behavior of a three-dimensional reinforced concrete frame under horizontal and vertical load effects. For this purpose, the experimental model which has four slabs and two equal spans for each direction was produced as a one-storey in 1/2 scale. Due to the inelastic behaviors of concrete systems, their scaling method is very difficult. The real building model material properties are used in this scaling building model. In the experiment, according to TS500, steel experimental setup was created and projects were prepared to load the model vertically with a load of 10% from the total load capacities of columns. Accordingly, the axial load capacities of columns with a C25-S420 material properties was calculated as 365kN respect to cross-sectional area of concrete and reinforcement bar. In Erciyes University Earthquake Research Laboratory, experimental researches started with load-controlled and completed with displacement-controlled methods. During the experiments, the development of the cracks that occurred in every cycle was recorded. As a result, hysteresis curves, strength envelope, stiffness change and energy consumption values were revealed by LVDT readings. Experimental results are compared with analytical data and the accuracy of the axial loader system in load transfer has been proven. In this study has been tried a system that was developed for transferring axial force to more than one column.
