Experimental results on scour at abutments under unsteady clear water flow condition are presented. Three shapes of short (abutment length/upstream depth < 1) were tested, namely, rectangular/vertical wall, semi-circular, and trapezoidal/45° wing-wall embedded in uniform sands two sizes having d50 = 0.52 mm 0.712 mm. The unsteadiness the is considered form flood hydrographs three forms, name...

Abstract This paper demonstrates the importance of assessing whirl flutter stability propeller configurations with a detailed aeroelastic model instead local pylon models. Especially growing use electric motors for propulsion in air taxis and commuter aircraft becomes an important mode instability. These often include which are powered by lightweight located at remote locations, e.g. wing tip. ...

Abstract This study employs the finite element-based CSiBridge v.20.0.0 software to examine response of a single-cell prestressed box-girder bridge subjected Indian loading conditions. The analyses is carried out on simply supported considering specifications Road Congress (IRC) 6:2017, IRC 18:2000 and 21:2000. An existing model skewed validated with published one. A convergence conducted for d...
