Experimental study on weighing of prestressed concrete T-shaped rigid frame in swivel construction
Based on the relationship between friction moment of spherical hinge and unbalanced moment of rotating body,the stress state of bracket after demolition is judged by using a T-shaped rigid frame bridge with upper span of Beijing-Shanghai railway.By calculating the friction coefficient and eccentricity,the bridge weighing test equipment is determined,and the weighing test plan and counterweight plan are obtained,which provides technical reference for the development of similar swivel construction bridge weighing test in the future.
