ANCHORAGE OF BENT BAR IN REINFORCED CONCRETE EXTERIOR JOINTS (PART 1)

By 實 若林, 宏一 南, 泰志 西村 and 伸郎 今仲

Abstract

An experimental study is made to know the effect of anchorage location of the straightvertical portion following the 90°bend on the reduction of load carrying capacity of exteriorjoints. Experimental variable is length to the straight vertical portion following the 90°bendfrom internal column face on top and bottom bar.Main discussion is concentrated on the anchorage strength, failure mechanism, slipbehavior of bent bar and hysteretic characteristics under repeated loading. It is concludedthat the load carrying capacity of exterior joint is affected by location of the vertical bar inexterior joint and the anchorage strength of bottom bar is smaller than that of top bar.An experimental study is made to know the effect of anchorage location of the straightvertical portion following the 90°bend on the reduction of load carrying capacity of exteriorjoints.
