Webachieved by placing post-tensioned strands in a cast-in-place deck [12]. Bridge girders achieve continuity via external tendons [13, 14]. Tan, K.H. and R.A. Tjandra created continuity for bridges with partial continuity by using an external tendon [15] and in- dicated an increase in the load carrying capacity. WebConfiguration of a multi-girder bridge. In multi-girder construction, a number of similarly sized longitudinal plate girders are arranged at uniform spacing across the width of the bridge, as shown in the typical cross section below. The deck slab spans transversely between the longitudinal girders and cantilevers transversely outside the outer girders. http://onlinemanuals.txdot.gov/txdotmanuals/bpd/preliminary_design_features.htm foley induction versus pitocin
