A new straightforward method for residual stress measurement is presented. A specimen is cut in half along its diagonal by using electric discharge machining, and the deformation benchmarks are measured to determine the displacements caused by release of the residual stresses. Analytically, to verify calculation accuracy of the new method, the known stresses are applied in finite element model as...
Chaotianmen Yangtze River Bridge in China is a semi-supporting, steel-truss, and tied arch bridge with a main span of 552 m, marking the world’s longest center span of the same type. The wind-resistant behavior under yaw winds was investigated via wind-tunnel tests of 1:100 scale-downed full bridge aeroelastic models. The service stage and four key construction stages were considered in the tests...
