To guarantee the stability of the frame in strong earthquake motion, and on the basis of analysis on the concept of “ capacity design ” in the above three countries seismic design provisions, it is advised that the moment amplification coefficients at the bottom sections of columns for the frame structures in some seismic intensity be increased to reduce the possibility of the frame column yielding. taking the above three countries seismic codes as reference, it is recommended that it be added details of seismic design by using diagonal shear reinforcement to safeguard beams against sliding shear failure, when the positive - negative shear forces are reverse and the ratio is high
為了保證在大震作用下框架結構的穩定性，借鑒國外規范「柱-梁承載力級差系數」的思想，本文提出了對部分抗震等級的框架結構的柱端抗彎能力增強系數應予以提高，以降低框架柱屈服的可能性;參照國外有關規范的發展，本文建議對于正、負剪力反向且比值較大的框架梁宜增加交叉斜筋，以防止沿垂直裂縫發生嚴重的剪切錯動。 -
