Results in terms of interstorey drifts, base shear, failure mode, ductility requirements and joints rotational requirements demonstrate that neglecting the possible local damage of the exterior joints may lead to erroneous conclusions and unsafe design or seismic behaviour evaluation that subsequently may become critical in some cases.
In the analysis of the m-orientation workspace, a procedure for calculating this type of workspace was presented, and the relationship between this type of workspace and the requirement of rotational displacement was revealed.
For a scale-space representation based on a multi-dimensional scale parameter, one may also consider a weaker requirement of rotational invariance at the level of a family of kernels, for example regarding a set of elongated kernels with different orientations in image space.
Apart from the straightforward desiderata such as beam intensity and rotational cooling, less straightforward requirements on the source exist.
A new family of UP-equivalent PMs with high rotational ability and low requirements in terms of geometrical conditions is disclosed using displacement subgroup theory.
However, the existing UP-equivalent PMs suffer from the disadvantages of strict assembly requirements and limited rotational capability.
The advantages of no strict assembly requirements and high rotational capability of the newly developed PMs will facilitate their applications in the manufacturing industry.
The significance of primary creep is assessed for controlling subsequent creep behavior and discussed for its crucial role in satisfying the stringent design creep requirements for advanced rotational components.
Furthermore, its parallel part has the advantages of high load capacity, high rotational capability, and no strict assembly requirement, which is preferable in practice.
This methodology can easily be incorporated in the strategy of constructing structural configurations of minimum rotational response, which is the main requirement in the design of structures expected to sustain strong ground motions.
