  • To present preliminary ideas for evaluating bending moment and shear forces in propped Cantilevers, fixed beams, and continuous beams in response to different load conditions.
  • To teach notions of bend Moment and Shear Force to beams with various boundary and loading conditions.
  • The method for developing slope deflection equations and determining the solution for continuous beams, with or without settlement of supports.
  • The concept of influence lines, moving loads, and moving lines is explained to assess the maximal S.F. and B.M. for the same section when there are loads with different span roll loads of Pratt and Warrentrusses.


Propped Fixed beams and Cantilever

Propped Cantilevers Introduction -Degree of Kinematic and Static Indeterminacy of frames, beams, and Trusses. I was analyzing propped cantilevers with shear force and Bending Moment diagrams. Elastic curve-Deflection of rays of propped Cantilever.

Moving Loads and Influence Lines Introduction Maximum S.F. and B.M. for the given section, and the absolute maximum S.F. and B.M. because of a single focused load U. D load is longer than the span U. D load less than the span Two point loads with the same distance, and several point loads that are equal to evenly distributed load with a standard focal length.

The definition of an influence line is the SF Line of influence for BMload position to ensure maximum S.F. at a section load location for the maximum B.M. in one point in a section. Loading, U.D. load that is greater than the span U.D. load is more minuscule than the spanInfluence lines for the forces present in the Pratt and Warren Trusses parts.

Analysis of continuous beams that include settlement of supports using flexible and stiffness techniques. They analyze pin-jointed plane frames using stiffness and flexibility methods. Analyzing single-bay single-storey portal structures using only the stiffness method Shear diagrams of bending and force Elastic curve.
