Abstract:
The paper describes the requirements which were developed for deck joints for the Ontario Highway Bridge Design Code. The Code provisions apply to prefabricated joint assemblies which accommodate translation and/or rotation. The basic philosophy of the Code is that the minimum number of joints be used consistent with the need for articulation and drainage of the structure. Sources of movement and loads on deck joints are discussed in detail. Two types of joint are recognized: those which are sealed against penetration by water and open joints in which the flow of surface drainage is permitted. Requirements for each type of joint are given. Requirements for durability, skid resistance, attrition, noise, ease of inspection, maintenance and modification are expressed qualitatively. Requirements for installation, permissible gaps and anchorage are expressed quantitatively. Factors influencing the selection of the type of joint are given.
