摘要
考虑贮仓在地震反应中的自重影响,根据能量原理得到了贮仓支承柱的屈服剪力的P-△效应增大系数β_g,由重力效应因子α_g及延性系数μ所控制,为贮仓抗震验算时考虑P-△效应提供了依据。
Considering the effect of the dead weight or bins in earthquake response, themagnification coefficient of yielding shear force of supporting column of bins was obtainedwith energy principle. It was governed by the gravity effect factor α_g and the ductilityfactor μ. And it has provided a scale basis for the aseismic checking computations of binswhen considering P-Δ effect.
