In the pseudo-dynamic test all repaired cracks re-opened, but the one at the base section became dominant. At the time when the drift ratio at the top of the wall was 1.0 % (Fig. 16.6), the base section reached its ultimate deformation in flexure (conventionally identified with a 20 % drop in the moment resistance of that section compared to its peak prior value). At that point the ultimate chord rotation of the shear span of the base section ( moment-to-shear ratio, measured during the test to be 6.75 m on average) was 10.5 mrad, the crack at the base had opened to 2.5 mm and at the bottom of the 2nd storey to 1 mm. 

It is noted that the integrals evaluated to arrive at Eq. (2) result in self-truncaticm of the flux and cross-section moments, thus making Eq. (1) theoretically consistent with the transport equation. In addition, although the components of the diffusion coefficient in the x and y directions are different, the formulation is such that it is compatible with the numerical algorithms existing in most 2-D diffusion theory codes.

It is of interest to examine the differential equation satisfied by Such a differential equation may be obtained in either of two ways. First, it may be recovered directly from the population balance equation by multiplying Eq. (4.5.1) by i " and integrating over the subinterval to get the sectional moment equation in... 

On the other hand, if Eq. (4.5.10) is merely multiplied by x- we again obtain a differential equation for the sectional moment...

Here, the loads and moments characterize the operational demands, while cross-sections, moments of resistance and others are the parameters to be determined. Once Eq. 1.61 (b) has been solved for one dimensioning parameter, e.g., the wall thickness of a pipe loaded by internal pressure, the result from circumferential stress is ... 

This procedure is considered equivalent to applying the QMOM to each section of an arbitrary with [Ci-i/2,6-1-1/2] i = 1,2,..., Npp resulting in a set of sectional moments that can be defined as ... 

To relate the sectional moments to the positions and weights of the secondary particles, (12.340) is substituted into (12.339) thus the following result is obtained ...

Chu et al. [39] foimd that drapeability is dependent on three basic fabric parameters Yoimg s modulus (Y), the cross-sectional moment of inertia (I), and fabric weight (W) and expressed drape coefficient in terms of these three parameters, DC= f (BAY) where, B= Y/I. 

A 3D beam element finite element model (FEM) was analyzed using the commercial code ABACUS to obtain beam section moments at each point in the hot leg piping. These section moments have been used in spreadsheet calculations to determine the primary stress intensity and primary plus secondary stress intensity range values using the ASME NB pipe stress equations. 

ABAQUS is used to rnodei the hot leg piping for a four Brayton system. The model is used to determine the stresses due to thermal expansion during plant normal operation. The model is analyzed at the steady state normal operation point. The beam section moment results are used in spreadsheet calculations to perform ASME B PV code piping stress calculations.
