Through experimental study on three HRB400 steel bar reinforced concrete columns subjected to low cyclic reversed loading, the failure patterns, hysteretic curves and skeleton curves were obtained. The influence of longitudinal high-strength reinforcement ratio upon the hysteretic characteristics, ductile behavior and ability of energy dissipation were analyzed. The results show that the main failure pattern was bending failure; and with the increscent of the longitudinal high-strength reinforcing steel bar ratio, the columns can endure larger seismic loads and displacement; the seismic performance of the whole reinforced concrete columns can be effectively improved by arranging reasonable high-strength steel bars.

Service Load

The need of structural retrofitting and strengthening of different buildings, engineering structures or their elements is always present. Among the main reasons are demages and material deterioration due to aging, improper maintenance or physical damages; planed repairs; reconstruction or extension of the building; technical modification or complete change of operations inside the building or the structure, etc. In some cases operation of the building during retrofitting or strengthening of its structures has to be partially or fully stopped. In other cases the strengthening process takes place while the building is still operational which means that structures are strengthened under service loads. The main goal of this research is to determine the strengthening effect of reinforced concrete jacketing applied to columns under service load level. For that the experimental study of six reinforced concrete columns were carried out: four reference columns, both strengthened by jacketing and unstrengthened and two strengthened under service load. The main results of the research are presented.
