error en chequeo de estructura de acero

al correr una estructura de acero me aparece: Pu mayor que Pe --B1 is undefined (AISC - LFRD C1 - 2), Design can not be completed for this section. favor me puedan guiar que quiere decir el mensaje y que hacer para correr la estructura ya que creo que esta bien diseñada.

Hola, LRFD considera efectos de segundo orden mediante la amplifiación de momentos. Uno de esos amplificadores es B1 que se calcula según la fórmula C1-2 del código y debe ser mayor o igual a 1. En tu caso este valor es negativo debido a que la carga axial Pu es mayor que la carga axial de pandeo de Euler Pe y el miembro no se podrá diseñar. Revisa el Capítulo C punto C1 de LRFD.

Exelente respuesta de ReneM, yo agreraria en resumen incrementar la seccion.

yo agregaria revisar los coeficientes de pandeo antes de agrandar la seccion.
Saludos
