The following symbols have been used throughout: is the Stress at any point; is the Section Modulus of beam cross section. Fixed beams. According to John Case (1999) when a body is under stress, then that stress tries to change its shape and dimensions. 6R1 = 3000 + 900 = 3900. The maximum deflection occurs where the slope is zero. If however a beam rests on more than two supports or in addition any of the end support is fixed, there are more than two reactions to be determined. This type of beam may be used when the designer wants to control the deflection at the mid-span because the two fixed supports prevent rotation. The tables below give equations for the deflection, slope, shear, and moment along straight beams for different end conditions and loadings. However, we must consider a separate load case, when live load is applied to only one of the two spans. ie; here are some tips and tricks to help you get started.
