Its characteristic is that,both the moment due to angular dis- placement and the moment due to lateral displacement are calculated by the same unbalanced moment at a node.

Based on moment distribution of structural mechanics,comprehensive moment caused by secondary moment is calculated.

The method involves combining shearing force distribution with moment distribution, which analyses the internal force of the frames, and it can be expressed in series of equal ratio, the ratio and the first term of the series are also obtained.

Under the condition of lesser unknown numbers, the method of moment distribution is one of the better methods in solving a statically indeterminate beam.

Study on the Outcome Check Method to Calculate the Statically Indeterminate Structure by the Moment Distribution Method;

The paper introduces an idea that taking a multi - span continuous beam as a distribution element joins in the moment distribution method, and recurrence formula which the bar - end rotation stiffness of arbitrary -span continuous beam and carry - over coefficient of joint moment is derived, so the idea can be put in practice.

This articles combines matrix with moment distribution method, and definitely points out that moment distribution is an exact calculating.

By analyzing substructures and according to the concept of momentallocation method,this paper presents a substructure moment allocation method for indeterminate rigid frame.

The calculation result of multiple continuous girders given by traditional moment allocation method is only an approximate solution.
