A weighted residual parabolic acceleration time integration method for problems in structural dynamics
(Walter de Gruyter GmbH, 2007)
In the proposed method, the variation of displacement in each time step
is assumed to be a fourth order polynomial in time and its five unknown coefficients are
calculated based on: two initial conditions from the previous ...
Investigations of shear behavior in reinforced concrete boxes
(American Concrete Pipe Association, 2008)
Box culverts have been used increasingly since 1965 to meet drainage requirements where the site conditions and loads acting upon them have been appropriate. It is believed that 80% of single barrel culvert installations ...
