The structure parameter influences on lateral stability, such as crankle rigidity ratio of arch rib, arch axis coefficient, arch high span ratio, lateral rigidity of bridge decking and arch rib ratio, the effect of non-orientedly conservative loadings of bridge deck, lateral wind loadings were discussed. Corresponding numerical charts were given, and they may be of some reference value and helpful to the parameter design of ribbed arches.2. In this paper, the example bridge is a long-span half-through CFST arch bridge of a 100m span in Yi Lan.

Based on the present findings, it appears that all the Taiwan WAIS-Ⅲ working memory index, the single Arithmetic and the Digit Span subtests, and the span scores of the Digit Span subtest could adequately discriminate individuals without working memory impairment, but had poor sensitivity on detecting the patients who evidenced working memory impairment. Accordingly, it is suggested that clinicians should gauge the working memory index by a composite of the Arithmetic, the Digit Span, and the Letter-Number Sequencing subtests if possible. Otherwise, a caveat should be taken with care to interpret the working memory index, as estimated by a composite of the Arithmetic and the Digit Span subtests, because the chance of the increasing false negative rate becomes ineludible.

The stretching influence on the near trusses should be considered when using the stretching-twice method, and the construction is hard to be controlled. The Harbin exhibition sports center with a 128m support span, attached to a deep design calculation of the super-large span prestress truss string structure, stretching once in tension bed method is brought forward for the bottom cable of the single truss string structure. From calculation research on the friction force between the tension bed and the truss string structure, the friction influence is considered for the displacement method of the middle of span, with the action of the fixed cable stress. This method, with vertical displacement of the middle of span as its main control target for prestress stretching, is successfully applied in the prestress stretching construction of the project.
