Web18. aug 2024 · Check on ‘Auto Calculate Effective Length Factors’ for the program to internally calculate the effective length factor. 1. Calculate stiffness, S (=EI/L), of the members which are connected to the ‘Member A’. If the joint of the flexural member is fixed or hinged as shown in the figure 2 below, the stiffness, S, is modified as indicated. 2. WebAnswer: Hello, The software performs the check for the sections based on the moments between the bracings, in the model, sent the bracing definition is not provided hence the design was performed the maximum negative moment in the bridge rather than design for a moment near contra flexure points.

Web20. apr 2024 · Common choices of wire strand are 12.9mm dia, supergrade 7-wire with 15.24mm dia, and Grade 270 with 7-wire. Typical prestressing design assumptions are as follows: - 75% jacking - Modulus of Elasticity = 195,000 Mpa - Anchorage draw-in = 6 mm - Coefficient of friction = 0.20 ~ 0.25 - Wobble factor = 0.002 ~ 0.0033 per meter Web1. jan 2024 · The arch portion of bridge has a span of 140.27 m and rise at the crown is 20.58 m which accounts to a rise-to-span ratio of 1:6.8. The arch supports ten spans of deck, each of 21.6 m, which sums up to a total span length of 216 m. Moreover, the overall length of the superstructure is 236 m which includes the abutment wing walls. http://www.midasbridge.com/en/blog/casestudy/design-of-girder-span-bridge-with-psc-section الصحه در عربی به چه معناست
