What reading level is Secondary Stresses in Bridges book?
To quickly assess the difficulty of the text, read a short excerpt:
18.
THE MOMEMTS AT ANY JOINT IN TERMS OP THE DEFLECTION ANGLE Since the truss is in equilibrium the sum of the bending moments at ends of members intersect- ing at any joint equals zero.
Thus in Fig.
^nl * Mn2 ♦ Mn3 ♦ ^^n4 = ^ (14) Expressing these moments in terms of several deflec- tion angles t as in eq.
LBbI (2 tni * tin) * ^ ^ln2 (2 tn2 ♦ tgn) * 2 j ln3 ■•■nl ln2 1, (2 tn3 ♦ t3n) ♦ 2 Eln4 (2 tn4 ♦ Un) = o d^) ln4 A similar equation may be written out for each joint, thus giving as many equ...ations as there are joints. In the many different equations will then appear as many different deflection angles "t" as there are joints. These equations can be solved simultaneously. Each value of t can be substituted back in the general equation of the bending moment for each member as in equation 11 or 12.
Mnm = 2^ (2 t^ ♦ t^^) (16) 19.
Each term of equation 15 contains I. For convenience let it be called K. Then equation 15 after dividing by 2 E each of the terms becomes: Knl (2 tnl + tin) * Kn2 (2 tn2 + t2n)= o (17) or 2(Knl t-nl ♦ Kn2 tn2 * ®tc.
