STATIC LOAD TEST STUDY OF A FLEXIBLE PEDESTRIAN SUSPENSION BRIDGE AT A TOURIST SITE
To evaluate whether the load-bearing capacity of a pedestrian suspension bridge meets the requirements,static load tests and finite element simulation software were used to study the stress,strain,and deflection values at the main girder control sections under different testing conditions,as well as the deflection values of the main ca-bles.The measured results were compared with the calculated results.The findings indicate that the measured de-flections at the main girder control sections and main cables are lower than the simulated values,with a reasonable deflection verification coefficient.The measured stresses at the test sections are normal,with stress verification coef-ficients ranging from 0.75 to 0.90.The longitudinal displacement of the bridge towers is small,and the incremental tension in the hangers from sampling tests closely matches the calculated increments.The bridge's stress state is nor-mal,and its structural strength and stiffness meet the specification requirements.The research results provide a ref-erence for the safety assessment of similar types of bridges.
