| Abstract: | Taking one old T-shaped rigid frame bridge which is located in Guangdong Province as an example,we establish the finite element model and get the theoretical data,on the basis of which we make the static load experimental scheme to do the spot test.Within the experimental,we get the deflection and strain data of the key section.By comparing with the theoretical data,the evaluation of the stress state and capacity can be got,then from the conclusion we can provide some reference for the bridges of same shape. |
