  2. Moment-resisting frame - Wikipedia

    en.wikipedia.org/wiki/Moment-resisting_frame

    Moment-resisting frame is a rectilinear assemblage of beams and columns, with the beams rigidly connected to the columns. Resistance to lateral forces is provided primarily by rigid frame action – that is, by the development of bending moment and shear force in the frame members and joints. By virtue of the rigid beam–column connections, a ...

  3. Bending moment - Wikipedia

    en.wikipedia.org/wiki/Bending_moment

    Shear and moment diagram for a simply supported beam with a concentrated load at mid-span.. In solid mechanics, a bending moment is the reaction induced in a structural element when an external force or moment is applied to the element, causing the element to bend.

  4. Shear and moment diagram - Wikipedia

    en.wikipedia.org/wiki/Shear_and_moment_diagram

    Shear and Bending moment diagram for a simply supported beam with a concentrated load at mid-span. Shear force and bending moment diagrams are analytical tools used in conjunction with structural analysis to help perform structural design by determining the value of shear forces and bending moments at a given point of a structural element such as a beam.

  5. Rigid frame - Wikipedia

    en.wikipedia.org/wiki/Rigid_frame

    The secant stiffness of the connection is compared to the rotational stiffness of the connected member as follows, in which L and EI are the length and bending rigidity, respectively, of the beam. If K s L/EI ≥ 20, it is acceptable to consider the connection to be fully restrained (in other words, able to maintain the angles between members).

  6. Moment distribution method - Wikipedia

    en.wikipedia.org/wiki/Moment_distribution_method

    The moment distribution method is a structural analysis method for statically indeterminate beams and frames developed by Hardy Cross. It was published in 1930 in an ASCE journal. [ 1 ] The method only accounts for flexural effects and ignores axial and shear effects.

  7. Weld access hole - Wikipedia

    en.wikipedia.org/wiki/Weld_access_hole

    Side view of a beam with two weld access holes cut into the web. Also the flanges have been beveled in preparation for welding. The weld access hole or rat hole is a structural engineering technique in which a part of the web of an I-beam or T-beam is cut out at the end or ends of the beam.

  9. Moment redistribution - Wikipedia

    en.wikipedia.org/wiki/Moment_redistribution

    Further increment in load does not increase the moment at the points where the plastic hinges are formed. The increased load increases the moment in the less stressed sections of the beam; hence due to this, further plastic hinges are formed. This process of shift of application of moment in the beam is termed as moment redistribution in a beam ...
