- Abstract:
- In order to study the plastic hinge length of in vitro prestressed combined millet under the action of negative bending moment, the influence of cross-section support conditions, cross-height ratio and geometric properties on plastic hinge length and other parameters was analyzed by using the cantilever beam model. The analysis results show that the mechanical properties of the composite beam under the action of negative bending moment are controlled by stability, and the length of the unilateral plastic hinge of the support is about 0.5 times the height of the web of the copper beam, which does not change significantly with the change of cross-section geometry and loading mode.
