０﹒８５ｆ’ｃ是以矩形斷面為基礎，去產生等值的矩形應力塊做為混凝土平均壓力值。然而，非矩形斷面的樑柱，０﹒８５ｆ’ｃ在缺角或非均勻斷面的區域，應該對於矩形應力塊做形狀或取值的修正，亦即壓力區不是矩形應力塊或非０﹒８５的數字。

The Meaning of 0.85f'c
Abstract
In the concrete structures, the theoretical assumption of 0.85f'c is the rectangle shape for the beam, column, and uniform-thickness plate members, or the 0.85f'c should be change the pressure stress shape or the average value, 0.85 to fit the special-shaped beam, column, and various-thickness plate members.
