Formulas: Design of Connections and Supports

Equation C-B3-7

Formula 2

If $K_{s} L / E I \geq 20$, it is acceptable to consider the connection to be fully restrained (in other words, able to maintain the angles between members).

Formula 3

If $K_{s} L / E I \leq 2$, it is acceptable to consider the connection to be simple (in other words, it rotates without developing moment).

Formula 4

$K_s = 20EI/L$ (text_label - position: top-left, above steep dashed line)

Formula 5

$K_s = 2EI/L$ (text_label - position: bottom-right, above shallow dashed line)
