| Abstract: | Based on the properties of the unit step function, through the analysis of different load characteristics of continuous beam bending moment equation, the moment equation of the beam is established by the unit step function, unified equation and deduced the continuous beam deflection. The procedure is regular, and the program is useful torealize the computerization, which can contribute to the analysis and calculation of the internal force of continuous beam. |
