RESOLUgAO DE EXERCICIOS, COM SUAS DEVIDAS JUSTIFICATIVAS.
Exercicio 1:
O valor da tensao maxima de compressao na viga prismatica de concreto armado da figura apos a cura do concreto, so com
0 peso proprio, vale:
Sao dados: Yc.=2,5tf/m3; Yaiv=2,0tf/m3; e=0,8m
A - a max = 20tf/m2
B - a max = 27tf/m2
C - CT max = 270tf/m2
D - a max = SZOtf/m�
E - a max = yootf/m�
O aluno respondeu e acertou. Alternativa(C)
Comentarios:
C - achei a carga da viga q=2,5tf/m3 achei o momento Maximo Mmax=45tf*m achei o momento de inercia
I = 0,0833m'�4 o ymax=l/2 ou 0,5m e joguei na formula de tensao maxima Tmax=(Mmax/I)*ymax portanto:
Tmax=270,ltf/m2
Exercicio 2:
0 valor da tensao maxima de compressao na viga prismatica de concreto armado da figura apos a conclusao da parede de
alvenaria, vale:
Sao dados: Yc=2,5tf/m3; Ya|v=2,0tf/m3; e=0,8m
