The Influence of Lap Splice of Longitudinal Bars in the Plstic Hinge Zone on the Nonlinear Behavior Characteristics of RC Piers and New Seismic Detailing Concept in Moderate Seismicity Region
초록
The influence of lap splice of longitudinal bars in the plastic hinge zone on the nonlinear behavior characteristics of RC piers has been investigated through the scale model tests. The seismic performance of bridge piers with lap splice is found to be insufficient due to the premature bond failure. On the other hand it is confirmed that the preventing lap splice in the plastic hinge zone enhance the seismic performance considerably even without the seismic details of transverse reinforcements. Bases on these experimental results new seismic detailing concept appropriate to moderate seismicity region has been proposed.
