Bearings for Bridges and Its Design | Civil Engineering

A bridge is designed to allow slight movement at a support. Usually a provision is made so that movement of 1 mm can take place per 30 m. It is also necessary to make provision to allow for changes in length due to live load stresses. In spans over 90 m long it is necessary to make allowances for expansions [...]

Calculation of Angles from Bearings | Compass Surveying | Surveying

Bearings of lines may be calculated if bearing of one of the lines and the included angles measured clockwise between the various lines are given. Bearing of a line = given bearing + included angle. Note: In a closed traverse, where local attraction is not suspected i.e. difference between F.B. and B.B of all lines is exactly 180°, we can [...]
