EXPERIMENTAL STUDIES ON JOINT MEMBERS OF STEEL FRAME WALL DEVELOPED FOR ASEISMIC REINFORCEMENT OF EXISTING BUILDINGS
|
´˜^i‰pjF
This experimental study evaluates the effect of a new type of crack-preventive bars on the performance of joint members. These joint members need to sustain the enough strength and ductility up to the load-carrying capacity of the steel frame. Main objectives are to confirm the effect of using mesh bars with spiral bars as the crack-preventive bar on the load-carrying ability and ductility of joint members of steel frame wall. In order to examine the load-displacement characteristic of joint members, six full scale models were tested. It is found from test results that joints with new crack-preventive bars have better performance in comparison with the current type.
