SOLUCION DE VIGAS CON UN PROGRAMACREADO EN MATLAB POR: Quichua Cabana Jess


2/16

MANUAL DE USO:

1. ABRIR EL PROGRAMA:

SE PUEDE ABRIR DESDE EL PROGRAMA .exe DE MODO QUE NO REQUIERA

ABRIR EL MATLAB, MAS SOLAMENTE SE NECESITA TENER INSTALADO EL

RUNTIME DE MATLAB. EL PROGRAMA CORRER POR MEDIO DEL

COMPILADOR.

2. INGRESO DE DATOS

3. COMPLETE LOS DATOS

4. SOLUCION DE LA VIGA HIPERESTTICA


3/16

EL PROGRAMA OBTIENE REACCIONES Y MOMENTOS EN CADA NUDO.

A CONTINUACIN; ADJUNTO EL CDIGO FUENTE DEL PROGRAMA EN MATLAB
