The slope deflection method is a structural analysis technique used to determine the internal forces and displacements of indeterminate beams and frames by relating the slopes and deflections at the supports and joints to the bending moments. This method incorporates the principles of equilibrium, compatibility, and material behavior, allowing for the analysis of structures that have more supports or constraints than can be solved using simple methods. It is particularly useful in analyzing rigid frames and in dealing with statically indeterminate structures where traditional methods fall short.
congrats on reading the definition of slope deflection method. now let's actually learn it.
