چکیده مقاله
After recent earthquakes, concerns about seismic performance of old buildings have increased and special attention have been paid to reinforced concrete structures Buildings which have been built before 1970s have been reinforced with smooth bars without considering seismic effects To study the response them, three half scale columns have been tested Reinforcement details are similar to those of available old uildings with three types of splicing details: continuous longitudinal reinforcement, straight lap splice, and hooked end lap splice The tests indicated hysteresis response, deformation capacity and strength of the mentioned columns The initial response was that of sectional roperties, over post yield range the behavior shows relatively low ductility, flextural crack pattern, and relatively large slip of reinforcement
