To find the best cable position, a method making use of the sectional stress influence line of core concrete at arch footing is put forward.

A 15 storey reinforced concrete shear core building and a steel girder arch bridge have been chosen as case verification.

In the metamorphic core complex (MCC) and the metamorphic arch, Jiangxi and Hunan area, there is an obvious correlation between the late brittle fault and the early subordinate ductile structure.
