Generally, metal bridges are metal bridges, and steel metal bridges are the most commonly used. Steel bridges are warmly welcomed by the market because of their excellent performance and affordable price. With the development of galvanized steel technology this year, galvanized steel bridges are very popular. Most cable bridge manufacturers use galvanized plates to make steel bridges.
For the case of galvanized plate bridge, the maximum deflection of the middle position of the bridge span should not exceed 10mm when the span of the bridge is 2 meters, which is stipulated in JB/T10216-2013 standard and JB/T10216-2000 standard.
The formula for calculating the deflection of the bridge is Ymax= 5ql ^ 4 / (384EI).
The Ymax in the calculation formula represents the maximum deflection (unit mm) of the middle position of the bridge span, the Q in the calculation formula is the standard value of average load (unit kn/m), the E in the formula is the elastic modulus of steel, and the I in the formula is the cross-sectional moment of inertia of steel.
