Selection criterion of bridge expansion joint:

Example: the design of bridge structure displacement along the center line of the 95mm, with its 40 degree oblique joints, calculated according to the formula of delta Lr=73mm, Delta Lp=61mm used this model is suitable for telescopic seam。 At the same time to note that the strip in the middle as quasi maximum horizontal momentum in the wrong direction before and after the two should not exceed 40mm if the calculation is found in excess, dislocation and expansion must choose a larger size seam。 The design, such as a sidewalk, structure proof wall, must be the point of view of design, size data is provided to the factory, to facilitate the overall manufacturing plant according to the design requirements。
