WebJun 28, 2024 · RAM Concrete automatically considers the eccentricity of pinned beams that frame into concrete columns. This is accomplished by shortening the physical beam length to the face of the column and adding a rigid link that transfers the beam reaction to the column centerline. A practical application for this option is the design of columns ...

WebFeb 8, 2024 · When transverse force is applied on a section of beam, the stresses produced will be known as bending stresses. Consequently, applied forces cause the bending moment which is commonly quantified as force x distance (kN-m). While measuring the bending, the force must be perpendicular to the moment arm.
WebThe design of a pinned connection is a good example of the idealization of the reality. A single pinned connection is usually not sufficient to make a structure stable. Another support must be provided at some point to prevent rotation of the structure.
