In this paper, in addition to introduce a hybrid structural system contained local isolators and dampers, its behavior and functional capabilities were studied on a conventional structure. For this purpose, an RC frame building with six-story was designed based on valid codes and then, in four cases based on the number of spans, it was split into two separate adjacent frames. Base isolation was...

the current study focuses on the experimental investigation of frp strengthening of rc portal frame subjected to combined vertical and horizontal loads. the main target of this research is to enhance the proposed structural properties that the rc portal frame had before the seismic occurrences by providing retrofitting of both columns and joints with more deformation capacity. the effect of var...

The pendulum impact tests were carried out on one RC frame column and four free-standing columns. effect of axial compression ratio reinforcement the resistance columns compared by means dynamic time curves framed freestanding under impact. test results show that with same load, though presence loads can play a positive role (e.g., reducing residual displacement), it may lead to more severe loc...

Experimental and numerical investigations on the retrofitting of half-scale wall-like reinforced concrete (RC) columns were conducted. The axial compressive behavior control un-strengthened RC column (having a section aspect ratio four) was compared with strengthened columns. by employing external confinement through fiber-reinforced polymer (FRP) wraps and/or steel/FRP strips with/without modi...

In this study, the monotonic and hysteretic behavior of poorly detailed reinforced concrete (RC) columns under lateral loads is simply modeled by SAP2000. It has been shown in literature that flexural, reinforcement slip shear deformations contributed to deformation. The responses RC due each these deformations, were determined. Under pushover loading, summed up create column. load-deformation ...
