WebFeb 22, 2001 · Results show that bending moments are negligible and the process of taking fixed joints will affect the overall structural weight only by a small percentage. As a rule, if the axis of members are coinciding at joints, taking the joint fixed, even if the members are tubular and welded connection, will not show considerable bending moment.

WebOct 24, 2024 · 1] For pinned connection, it is applicable to buildings in moderate to high seismic regions where the SMRF (columns and beams) are to carry lateral seismic forces plus gravity loads, consequently these columns' moments have to be resisted by footings (spread or mat) to maintain stability.
