calculo deflexión elementso de acero

Hola, mi pregunta es si para el cálculo de deformaciones en los elementos de acero se deben considerar cargas mayoradas o cargas de uso???
esto pensando en diseñar considerando las deflexiones máximas que se desean controlar en una estructura.

Todo estudio o análisis de deformaciones se hace con cargas de servicio.

Saludos.

Tiene razon, siempre se hace con cargas de servicio, es decir sin mayorar ni aplicar ningún, la deflexion por carga viva es δcv=5/384WL4/(EI) y por carga muesrta es δcv+cm=5/384WL4/(EI), según el AISC, donde w es la carga sin mayorar en klb/in, E, modulo de estaslicidad del acero, I, inercia y L, la luz libre

saludos
