Description
Technical field
Toppled the present invention relates to a kind of ancient building pin and deform loading measurement apparatus and its measuring method.
Background technology
Pillar integrally topples inevitable and common problem in always historic building structure.Study real post
Son topples to deform then seems particularly significant to the influence for studying ancient Wood construction.But in reality, an in-service ancient building scene is entered
Row, which pushes away, covers loading and unrealistic, and traditional the inclinations load mode in laboratory is difficult to reappear pillar in real ancient Wood construction to topple
Deformation condition：On the one hand, because true ancient building bottom of the pillar and stone base of column stone mutually separate, excessive angle of inclination can be very
Cause pillar that rollover or unstability occurs soon, therefore the angle of inclination of every grade of loading is very small.On the other hand traditional loading side
The axle pressure of trabeation is applied by jack in formula, axle pressure meeting pair during column inclination on such top
Pillar produces moment-in-plane and second-order effects and it can not be kept stable.Because bottom of the pillar is usual in traditional load mode
Using be hinged or rigid connection, therefore above mentioned problem and it is not present, but the boundary condition separated with real center pillar the stone base of a column and pillar is simultaneously
It is not consistent.
The content of the invention
In view of the deficiencies in the prior art, the technical problems to be solved by the invention are to provide a kind of ancient building pin and toppled change
Shape loads measurement apparatus and its measuring method, can not only react the boundary condition of true ancient building pin bottom cut-off, and and can exists
Ancient building pin stable in ancient building pin tilting procedure is kept to topple the loading measurement apparatus of deformation.
In order to solve the above-mentioned technical problem, the technical scheme is that：A kind of ancient building pin, which topples, deforms loading survey
Measure device, including concrete bearing platform to the fixed measured ancient building pin bottom placed vertically and to be set in
