【摘要】 目前,我国仍没有一套关于港口起重机地震载荷计算的行之有效的方法,文中参照日本《JACS 1101起重机抗震设计》中的一级地震动修正烈度法,考虑了我国的地域类别修正系数、地面类别修正系数、加速度倍率、起重机类别等因素,研究得出了一种适用于我国的起重设备地震载荷计算方法.此方法为静力分析法,考虑因素较为全面,计算简单易行.更多还原

【Abstract】 At present,China still does not have a effective way to calculate the seismic load of port cranes.Based on the correcting intensity method of first level ground motion from《JCAS1101-2008 Guideline for seismic desugn of cranes》of Japan,a calculation method of crane seismic load suitable for China is put forward,considering the correction factor of geographical groupings,ground category correction factor,acceleration rate,the type of crane and other factors in China.The method is static method that considers the comparative factors and operating simply and easily.更多还原
