An experiment of two span reinforced and prestressed concrete beams for the ductile behavior

철근 및 프리스트레스콘크리트 2경간 연속보의 연성거동에 관한 실험

One of the important aspects of ductility is redistribution. To see the difference of redistribution between reinforced concrete members and prestressed concrete beams, two span continuous concrete beams are tested. From the test results, we can get important information on the redistribution ratio. After occurrence of crack at support section, the redistribution ratio increased and after yielding they fluctated very much. Compare with reinforced concrete, the redistribution ratio of prestressed concrete beam changed more abruptly after yielding. Both of the them show limited redistribution up to 70%.
