    The soil-structure interaction analysis is based on a finite-element pipe-soil model which allows calculation of both loads acting on the pipe and the moments, thrusts, and shears at points in the pipe circumference. These pipe wall forces are then used to determine reinforcing requirements for both ultimate limit states and crack ://(ASCE)PS    Shear Forces and Bending Moments Consider a cantilever beam with a concentrated load P applied at the end A, at the cross section mn, the shear force and bending moment are found Fy = 0 V = P M = 0 M = P x sign conventions (deformation sign conventions) the shear force tends to rotate the material clockwise is defined as

      Structural responses include moments, thrusts, and shears as well as responses specific to the pipe type such as plastic penetration for corrugated metal and crack depth for reinforced concrete. A local plot of the pipe is also pro- vided (see Figure 7). â ¢ Results :// This matrix relates the member-end rotations, vertical deflections, and horizontal translations to the internal bending moments, vertical shears, and horizontal thrusts.

Computation of deflection of structures is necessary for the following reasons: a. If the deflection of a structure is more than the permissible, the structure will not look aesthetic and will cause psychological upsetting of the   designs fixed or tied arches that have an axis of symmetry and are loaded symmetrically.

The arch can be defined either by the intrados and extrados centers or by the coordinates, segment lengths and thicknesses of segments for the axis of the arch barrel.

Computed values include geometric properties; factored moments, shears, thrusts Manual/ARCH Users Manual methods of linear-elastic analysis usually lack generality because the dominating requirement is the minimization of number processing.

The matrix stiffness method of frame analysis for plane, rigidly connected frames can handle arches, beams, and frames with ease, and the model takes into account both flexural and axial ://   bending moments, shears, and axial forces in all its members, as well as the external reactions, can be determined by using the equations of equilibrium and condition, otherwise the frame is either unstable or statically ~gebland/CE /CE PDF Lecture.

In the case of beams supporting uniformly distributed load, the maximum bending moment increases with the square of the span and hence they become uneconomical for long span structures. In such situations, arches could be advantageously employed, since they [ ] Bending moments and shears will be absent if the arch is parabolic and the loading uniformly distributed.
