Sismo (factor de escala) en Ram Elements

hola, soy de mexico y estoy haciendo un analisis dinamico de un edificio de 4 pisos, el programa me pide un factor de escala y un % de amortiguamiento, cuales son los que se usan en Mexico

El factor de escala a utilizar inicialmente , es decir sin escalar el sismo, es el original que te da el espectro que calculas con los parametros del suelo y la altura del edificio y tipo , luego debes tomar un valor de 1. asi lo estipula tambien el manual de rams elements carga sismica y espectro de respuesta que dice "ingrese 1 si el espectro de respuesta no necesita ser escalado"

el amortiguamiento se utiliza generalmente el 5%

Amigo, si tu espectro no lo redujiste por Q, entonces el factor de escala es 1/Q para que le aplique la fuerza reducida al modelo, solo recuerda que el cortante basal dinamico debe ser almenos el 80 a 90% del estatico, por lo que hay que revisar si el factor de escala se debe modificar un poco
