For columns with very small or zero

For columns with very small or zero calculated eccentricities, the ACI Code recognizes that accidental construction misalignments and other unforeseen factors may produce actual eccentricities in excess of these small design values. Regardless of the magnitude of the calculated eccentricities, the ACI Code limits the maximum design strength to 0.8(φ)P0 for tied columns. Here, P0 is the nominal strength of the axially loaded column with zero eccentricity.

对于列很小或为零计算的怪癖，ACI 规范确认意外建设失调和其他不可预见的因素可能会产生实际的怪癖，超过这些小的设计值。无论计算怪癖的严重性，ACI 规范限制到 0.8 （φ） 的最大设计强度为绑定列 P0。在这里，P0 是零偏心受压柱的名义强度。

对于非常小或为零计算怪癖列，ACI规范认识到，意外建设失调和其他不可预见的因素可能会超过这些小设计值的产生实际的怪癖。无论计算怪癖的幅度，ACI规范限制最大设计强度0.8（φ）为P0并列列。在这里，P0是零偏心轴心受压构件的名义强度。
