      Abstract: Internal force calculation problem under the effect of horizontal load of the high-rise buildings is crucial in structural design, which has been studied in this paper.It first gives some basic principles and calculating hypothesis of all kinds of calculating methods;then, does the comparing calculations by means of concrete examples.The result shows that structural matrix displacement calculation is precise and can be used widely; D-value method has a clear definition, is suitable for calculating by hand; the precision of calculation can meet the demands of engineering design, and can be used in the calculation of internal force of the general framed structure.Reverse bend point method can be used as correction by computer calculation.
