【摘要】 提出了浮放式设备抗倾覆高宽比限值的概念,建立了结构—浮放式设备体系的力学模型,推导了地震作用下建筑内浮放式设备抗倾覆高宽比限值计算公式,并对影响设备高宽比限值的因素进行了分析。结果表明,质量对设备高宽比限值几乎没有影响,摩擦系数和地震动强度是影响设备高宽比限值的主要因素,而场地条件对设备高宽比限值的影响与摩擦系数有关。更多还原

【Abstract】 The conception:limit of height-width ratio of free-standing equipment in structures to resist overturn caused by earthquake was presented,and the formula for calculating it according to the mechanical model of structure-equipment system was established.Base on the analysis of different parameters,the results show that,the mass of equipment has little effect on the limit of height-width ratio of free-standing equipment,the coefficient of friction and the intensity of ground motion are main factors,and the affect of site condition to the limit of height-width ratio of free-standing equipment is influenced by coefficient of friction.更多还原
