trussThe rotation angles at beam ends of railway.pptx

The rotation angles at beam ends of railway steel truss bridges are
crucial to train-running safety. The upper limit of the rotation angle
is specified in many bridge design codes. For example, the upper
limit in the Chinese railway design code TB-10002 (2017) is 1.0&
rad. A rotation angle exceeding the upper limit can result in irreg�ular track geometry, induce significant vibration, and threaten train�running safety. Therefore, it is important to study the rotation angle
at beam ends of long-span railway bridges.
