| 摘要： | The original Illinois 2399 bridge railing design has been used as a retrofit railing on selected structures. A structural analysis indicated that strength of the railing could be increased by changing positions of the lower and upper rail elements to obtain more beam strength along the top. The modified design (Illinois 2399-1) was tested to performance level two of the 1989 Guide Specifications for Bridge Railings. Acceptable performance was demonstrated. |
