Find the allowable moment capacity M or C M as applicable an

Find the allowable moment capacity, (M\' or C M\' as applicable), and shear capacity, V\', for each of the following beam sections. Unless otherwise indicated, the members are in a dry service condition, in a normal temperature range, unincised, and braced against lateral buckling. I.

Solution

Due to collapse load apply,

1)M=1•5×4=6KNm, V=1•5÷4=•375KN

2)M=1•2×8=9•6(Due to service load),V=1•2÷8=•15KN

3)M=•9×8=7•2ו25=1•8KNm, V=•9÷8=•1125ו25=•028KN
