The fixed supported beam AB is strengthened using the simply supported beam CD and the roller at F which is set in place just before application of the load P. Determine the reactions at the supports if EI is constant.

Problem 12-125The fixed supported beam AB is strengthened using the simply supported beam CD and theroller at F which is set in place just before application of the load P. Determine the reactions atthe supports if EI is constant. Step-by-step solution Step 1 of 11 ^A beam AB fixed at both ends is loaded centrally and strengthened by a simply supported beamCD as shown in Fig. 16-57a. The reactions at the supports are to be determined.
