  • 一般鋼結構建築物均採用抗彎矩構架系統於地震下來消散地震能量,其非彈性變形通常集中於梁柱接頭區,造成建築物因梁柱接頭區韌性不足產生破壞。本研究主旨在於將梁柱交會區上的非彈性變形,轉移至指定塑性區,並藉由改良式接合板將地震下所承受的彎矩轉換成拉力和壓力的軸力來消散地震能量,並且可以延遲接合板發生挫屈的時間,進而提高梁柱接頭之耐震能力。本研究以有限元素分析進行等值應力分析和塑性需求分析,並以5組具消能改良式連接板應用於梁柱接頭進行實尺寸反復載重試驗,印證其結果,此方法可有效提升梁柱接頭耐震行為。


    The general Steel buildings are made of Moment Frame to dissipate seismic energy in an earthquake,The inelastic deformation of concentrates at the end of beam columns joint ,causing the building due to lack of toughness beam columns joint cause damage.This study aims to inelastic deformation on the beam column joint transferred to the plastic zone,with this energy dissipation plate to hold the earthquake moments to converted the tension and pressure to dissipate seismic energy,and may delay the occurrence of continuing plate buckling time, and than to raise to increase the seismic capacity of the beam column join.The study use finite element analysis equivalent stress analysis and plastic require analysis,and the five kinds of energy dissipation continuing plate used in real size beams column joints cyclic loading test, The results prove that this method can effectively improve the seismic behavior of beam-column joints.
