Calculo del periodo en SAP2000 con rigidez lateral 12EI/L^3

hola buenas con todos..
estoy intentando calcular el periodo de una estructura suponiendo un grado de libertad por piso y que la rigidez es 12EI/L^3....
Aqui mi problema como hago que el sap2000 tome esta rigidez para los elementos y que la losa solo considere desplazamiento en una sola direccion ...
de ante,ano gracias por su ayuda.....

En portico planos asigna un diafragma en la losa.
A todos los elementos no tienen que tener deformacion axial y deformacion por corte, por ende en la propiedades de los elementos la rigidez axial=1000000 y Rigides a corte=0 .

Estos seria lo mas aproximado.

O sube un modelo donde calculas tus datos de comparacion.
