Force Method. The reinforced concrete beam as shown in “Figure 1" has a constant cross sectional dimension of 10" x 12" (b x h). The unit weight of the concrete is 150 lb/ft3. The 28-day concrete compressive strength of the beam is = 4000 psi. Use the classical force method to analyze the indeterminate beam under the applied dead load only. Assume the following values of span length: L1 =...
