Assuming linear elastic bending with small deformations and planes perpendicular to the neutral axis remain plane after bending, then for a rectangular beam: Moment = (Yield Stress)*(Second Moment of Area)/(Distance of surface to Neutral Axis) For Ultimate Bending Moment, assume stress is uniform throughout the beam, and acting through half the distance from surface to neutral axis, then: Moment = Stress * (Area/2)*(h/4 + h/4) For a better visualization check out Popov's textbook, Engineering Mechanics of Solids, Chapter 6, Section 6.10
It is a monolythic concrete beam consisting of a web and a flange to form the shape of a"T" .
column cap plates are commonly used to secure the column head to a beam using bolts driven through the plate and beam bottom flange. The plate is welded to the column head usually with fillet welds although fully penetrating butt welds would be better since this would provide the greatest restraint to bending and shear (transverse/longitudinal) at the plate/column head junction.
Japan has a better technology.
huffman has a better compression rate.
