Analysis of Mechanical Behavior during the Demolition Process of T-shaped Rigid Frame Bridge with Hanging Beam
The T-shaped rigid frame with hanging beams has the characteristic of sudden failure under the influence of long cantilevers in the case of unilateral weight loss.Currently,for this type of bridge with severe diseases,demolition treatment is generally adopted.To ensure safety during the demolition construction period and prevent sudden collapse due to demolition,it is necessary to conduct a stress behavior analysis of the entire demolition process and propose targeted control measures.This article uses a real bridge demolition case,combined with the stress characteristics of the demolition process,to demonstrate the calculation points of demolition calculation,and conducts on-site verification,providing reference experience for similar bridge demolition.
