Abstract

The invention discloses a method for calculating the internal force and the deformation of a member or a structure under the action of multiple complex loads. The method comprises the following steps: (1) respectively solving reaction forces RA, RB and RC on a support according to practical loads acting on the member; (2) directly applying seven loads including q1, q2, q3, M, RA, RB and RC to a cantilever beam with one fixed end; (3) respectively making action effects corresponding to seven loads according to the required internal force or deformation; and (4) directly superposing to obtain a result. According to the method disclosed by the invention, the frame or the structure is directly considered as the cantilever beam with one fixed end, and then the action effects of various loads are made and then are directly superposed; compared with the traditional superposition method, the method has the characteristics of convenience and accuracy in calculation and easiness mastering, and is of great significance on developing and perfecting the subject of engineering mechanics.

Description

technical field [0001] The invention belongs to the technical field of engineering mechanics, and in particular relates to a method for calculating the internal force and deformation of a member or structure under various complex loads. Background technique [0002] The traditional superposition method is only when the component or structure is within the elastic range, the effect of the load is linearly related to the load, and there is no coupling effect between the various loads, the effect of the total load is equal to the sum of the effects of the individual loads; However, the calculation is still cumbersome when the component or structure is subject to complex constraints. [0003] At present, it is tedious to calculate the internal force and deformation of components or structures under various complex loads in engineering mechanics. Contents of the invention [0004] The purpose of the present invention is to provide a method for calculating the internal force an...
