Example 317

Given: Determine K-factors by using the Lui method for the frame shown in Figure 31.14a. E = 29,000 ksi (200 GPa).

Solution

Apply fictitious lateral forces at B and D (Figure 31.14b) and perform a first-order analysis. Detailed calculation is shown in Table 31.5. By using Equation 31.95, we obtain
