Alguien podrá apoyarme con algún ejemplo de análisis Pushover para marcos de acero en el programa RUAUMOKO?
Estoy trabajando un ejemplo, es un marco plano de acero a base de secciones tipo "W" pero al correr el programa obtengo resultados ilógicos, ya revise las propiedades de los materiales y al parecer todo está bien, y resulta que la estructura no colapsa.
Código: Seleccionar todo
