1、Section 11 ALUMINUM DESIGN 11.1 GENERAL The purpose of this section is to provide a location for indexing aluminum design, material fabrication, and con- struction specifications. 11.2 BRIDGES The SpeciJications for Aluminum Structures, Fifth Edi- tion, December 1986, published by the Aluminum Asso-
2、 ciation, Inc., as it applies to “Bridge and Similar Type Structures,” are intended to serve as a standard or guide for the preparation of plans and specifications and as a ref- erence for designers, fabricators, and erectors of alu- minum bridge and railing structures and their aluminum structural
3、components. Welding shall conform to Section 10 of the current AWS D1.2 Structural Welding Code- Aluminum, and workmanship requirements for Class II structures. 11.3 SOIL-METAL PLATE INTERACTION SYSTEMS The design of aluminum soil-metal plate interaction systems shall be in accordance with Section 1
4、2. Fabrica- tion and installation shall be in accordance with Section 23-Division II. 11.4 STRUCTURAL SUPPORTS FOR HIGHWAY SIGNS, LUMINAIRES, AND TRAFFIC SIGNALS The AASHTO Standard Speccjkations for Structural Supports for Highway Signs, Luminaires and Trafic Sig- nals shall be used for the design
5、and preparation of plans and specifications, fabrication, and erection of aluminum sign supports, luminaires, and traffic signals. Welding shall conform to Section 10 of the current AWS D1.2 Structural Welding Code-Aluminum, and workmanship requirements for Class I structures. Special consideration
6、may be given to certain support structures, which may be designed and fabricated according to the provisions of Ar- ticle 11.2, Bridges. 11.5 BRIDGE RAILING The design of aluminum bridge railing shall be gov- erned by Article 2.7; the fabrication and erection shall conform to Section 6 of the SpeciJ
7、ications for Aluminum Structures, Fifth Edition, 1986; and the welding shall con- form to Section 10 of the current AWS D1.2 Structural Welding Code-Aluminum, and workmanship require- ments for Class II Structures. The AASHTO Roadside Design Guide should be consulted for guidance on the safety considerations in the design of bridge rail. 337
