Improving co-development through process alignment

There has been a recent surge of enthusiasm icithin tlie automotive industry to build closer supplier relationships idthin the area of product development. One concept deemed central to these relationships is the alignment of development processes between the collaborating organizations, an area that is expanded upon idthin this paper. We suggest that synchronization can be achieved through the four key steps of process standardization, knowledge sliaring, alignment of existing practices, and continuous elimination oftcaste idthin the joint development cycles. A methodology for implementing these stages is presented along idth the underlying prindples on which it is based - the importance of joint teamworking and multi-company involvement idthin the alignment process is higlilighted. © MCB University Press.

Re-mobilization of pile shaft friction after an earthquake

During strong earthquakes, significant excess pore pressures can develop in saturated soils. After shaking ceases, the dissipation of these pressures can cause significant soil settlement, creating downward-acting frictional loads on piled foundations. Additionally, if the piles do not support the full axial load at the end of shaking, then the proportion of the superstructure's vertical loading carried by the piles may change as a result of the soil settlement, further altering the axial load distribution on piles as the soil consolidates. In this paper, the effect of hydraulic conductivity and initial post-shaking pile head loading is investigated in terms of the changing axial load distribution and settlement responses. The investigation is carried out by considering the results from four dynamic centrifuge experiments in which a 2 × 2 pile group was embedded in a two-layer profile and subjected to strong shaking. It is found that large contrasts in hydraulic conductivity between the two layers of the soil model affected both the pile group settlements and axial load distribution. Both these results stem from the differences in excess pore pressure dissipation, part of which took place very rapidly when the underlying soil layer had a large hydraulic conductivity.
