The required strength of bracing members with respect to the limit state of net section rupture is the expected brace strength. It should be noted that some, if not all, steel materials commonly used for braces have expected yield strengths significantly higher than their specified minimum yield strengths; some have expected yield strengths almost as high as their expected tensile strength. For such cases, no significant reduction of the brace section is permissible and connections may require local
reinforcement of the brace section. This is the case for knife-plate connections between gusset plates and ASTM A53 or A500 braces (for example, pipe, square, rectangular or round HSS braces), where the over-slot of the brace required for erection leaves a reduced section.

Это относится к knife-plate соединениям косынок и элементов связи по ASTM A53 или A500 (например, трубчатые, квадратные, прямоугольные или круглые элементы связи профилей HSS), где over-slot элемента связи, необходимый для монтажа, оставляет уменьшенное сечение.
