Question
sorry,what are these:
Step 3 Slope deflection equation
In section AB
MAB= MFAB+22EIL2θA+θB-3δLMAB= -12.5+4EI5θB MBA= 12.5+4EI52θB
In section BC
MBC= 0+2EI52θB+θC MCB= 2EI5θB+2θC
In section CD
MCD= -16.67+4EI52θC MDC= 16.67+4EI5θC
arrow_forward
Step 4 Equilibrium equations
Equilibrium equations
MBA+MBC= 0 -(i)MCB+MCD= 0 -(ii)
Now,
From i12.5+8EIθB5+4EIθB5+2EIθC5= 0EIθB125+EIθC25 = -12.5 -(iii) From ii2EIθB5+4EIθC5+-16.67+8EIθC5=02EIθB5+EIθC125= 16.67 iv
Solving equations (iii) and (iv), we get
EIθB= -6.548EIθC = 8.037
