SALUDOS A LOS AMIGOS DEL FORO

ESTAMOS DISEÑANDO CIMIENTOS RIGIDOS POR LA TEORIA DE LEBELLE (BIELAS Y TIRANTES), TOMANDO COMO REFERENCIA EL LIBRO: CÁLCULO DE ESTRUCTURAS DE CIMENTACIÓN" DEL ESPAÑOL J. CALAVERA, EN EL CUAL LIMITA LA TENSION DE FLUENCIA DEL ACERO A NO MAS DE 400 MPA... LO CIERTO ES QUE ESTE ACERO NO ESTÁ APARECIENDO EN EL MERCADO, SOLO BS-500...INTERESA OIR OPINIONES Y EXPERIENCIAS.

SALUDOS
ALEXIS

ENCONTRE LA RESPUESTA Y LA COMPARTO...LA TENSION DE DISEÑO DEL ACERO SE LIMITA A 400 MPA, PORQUE EN EL DISEÑO DE CIMIENTOS RIGIDOS NO SE CHEQUEA EL ESTADO LIMITE DE SERVICIO, DE ESTA FORMA SE GARANTIZA QUE EL ACERO TRABAJE A UNA TENSION MAS BAJA...O SEA, SI SE USA UN ACERO, CUYA TENSION DE CALCULO ES SUPERIOR A 400 MPA, DEBE TOMARSE ESTE VALOR...ESTO ME RECUERDA EL MISMO PRINCIPIO PARA DISEÑAR TENSORES NO FISURADOS, DONDE PARA CALCULAR LA SECCION DE HORMIGON, EL ACERO SE PONE A TRABAJAR A UNA TENSION BAJA.
