Abstract: Better understanding reinforced concrete behaviour greatly enhances ones grasp of design essentials and helps to improve them further. Therefore, especially laboratory research activities play an important role in designing earthquake resistant structures and retrofitting existing ones. Through experimental research activities fundamental principles can be put forward to prevent structures undergoing excessive damage during earthquakes. In this study it is aimed to present to seismic behaviour of a one-storey and one span reinforced concrete frame retrofitted by CFRP wrapping. Displacement controlled loading is applied and hysteretic curve of the system is obtained. The corresponding backbone curve is drawn and results are discussed in terms of strength and ductility. By identifying crack development in terms of crack locations and intensity it is aimed to track changes in system behaviour. With hysteretic curve has been demonstrated energy consumption. As a result of experimental data

Abstract: Post-tensioned concrete flat plate structures has many advantages such as reduction of overall member thickness and deflections. Several authors have discussed the influence of the tendon layout on deflections of flat plates. However, few information is available on the deflections of post-tensioned flat plate considering tendon layout types. In this study, flexural tests on a concrete flat plate specimen was performed in order to evaluate the deflection according to the two-way tendon layout. The test results were analyzed to propose the nonlinear finite element model taking into account the nonlinearity of concrete. This proposed model is capable of prediction of the deflections considering tendon layout.
