ANALYSIS FOR SEMI-INFINITE BEAM CASE


Step 1

Calculations for µ
µ= 0.44491422
µL= 6.22879909

Step 2

From equation 5.3 SG, we have the deflection distribution. It can be calculated from coefficients of A1 and A2. These
coefficients will form part of the equation 01 for the matrix formation .
Note that B1=B2=0

Calculation for coefficient equation 01

Coefficient A1= 0
Coefficient A2= 1 4EI µ^4v-q= -137.2


From equation 5.4 SG, we have the slope distribution. It can be calculated from coefficients of A1 and A2. These
coefficients will form part of the equation 02 for the matrix formation .

Calculation for coefficient equation 02

Coefficient A1= 1
Coefficient A2= -1 4EI µ^3(dq/dx)-1/µ(dq/dx)= 22.027
