The moments in the arch will be zero, if

DSI of structure depends upon

The shear center in the case of T-beam section is

If the shear force along a section of a beam is zero, the bending moment at the section is

A rectangular beam carries a maximum bending moment of M. If its depth is doubled, its moment carrying capacity will be

A pin jointed frame with with J number of joints and n, number of members will be a perfect frame if

If ki is the stiffness of i th member of a Joint, the distribution factor for the member is

When the load does not pass through the shear centre of the steel beam. It produces
