According to bending internal force figure, we can make sure the position of critical section and check the intensity and rigidity. So it is an emphasis to roundly master the bending internal force figure. But there is much difficult to protract the bending internal force figure in rigid frame due to multitudinous reasons. This paper gives some detailed analysis of shearing force, bending moment of internal force in rigid frame.

Bridge pile foundation on large-scale deposit body bears not only the vertical force transmitted from superstructure, but the lateral force transmitted from slope deformation, so the force situation is complex. The method of solving the internal force of piles which is simulated with solid elements is put forward in the paper. Taking Dahuaqiao bridge pile foundation as an example to carry out numerical simulation analysis. The distribution rules of axial force, shear force and bending moment of the pile in different position were analyzed. The results can provide the basis for the design and safety evaluation of bridge pile foundation.

Water tower as an important structure in glass plant production,its function can not be replaced.Water tower above 300 m3 needs to be designed according to the current structure design theory and specification by oneself.For the cylindrical tower that adopted inverted cone water tank,its additional bending moment takes the large proportion in the combination value of internal force on cylindrical body section.And its influence is larger than that of earthquake bending moment and moment of wind pressure,so effective measures should be adopted to reduce the influence of additional moment.In dealing with some aspects of large numerical calculation for internal force of water tower and design of cross section,the strong equation editor and calculation function of EXCEL are adopted to enhance the speed of calculation and design.

When shearing force or axis force is relatively great, great errors of moment arise when the method of pure bending is employed. A mechanics model is presented in this paper which explains the combinative action of bending moment, shearing force and axis force, and some related calculation formulas are hereby deduced.

This paper addresses the behaviour of multi storey structure considering soil structure interaction i.e. interaction between substructure of the building and soil. For this purpose a sample of 5 storey RC frames is analysed in conventional method with incremental static analysis for various load combinations and determines the parameters displacement, shear force and bending moment. Then a same 5 storey RC frame is analysed in numerical analysis using Finite Element Method (FEM) with raft foundation by assigning the soil properties to substructure and determine the parameters displacement, shear force and bending moment. According to the analysis results the parameters displacements, shear force and bending moment varies from conventional analysis to numerical analysis. Displacements of the structure increases, shear forces of the structure decreases and bending moment of the structure decreases at some points and increases at some points from conventional method of analysis to numerical method of analysis.

Consider a cantilever AB, carrying a concentrated load W at the free end B, Figure 10.1(a). At any section C, the load W is tending to shear the beam (Figure 10.1(b)), this being resisted by the internal force exerted on CB by the adjacent part AC.
