ABSTRACT
This chapter deals with the calculation of internal actions in statically determinate beams and frames. We have seen that statically determinate structures are those for which the reactions at the supports and the internal actions on any cross-section may be determined using only the equations of equilibrium. We will see subsequently that for statically determinate structures, a small deformation of one part of the structure does not induce reactions at the supports and does not cause a change in deformation of any other part of the structure.
