On the contrary, after the girder erection, a considerable amount of immediate deflection and long-term deflection due to dead loads
such as topping and common duct partially offset the camber.
Load (N/[m.sup.2]) Joist + compression layer dead load
3,500 Flooring + ceiling dead load
1,000 Partition walls dead load
1,000 Total dead load

The asymmetrical load was applied on the bridge model with different ratios of the live and dead load
components ([gamma] = p/g).
The initial shape of flexible cable under the dead load
g, considering the erection sequence, shall be expressed by the following equilibrium equation:
The vetor of elastic displacements [u.sub.e,c] of the structure subjected to the dead load
[F.sub.c] is calculated.
where RF = capacity reduction factor; [R.sub.n] = nominal capacity corresponding to the type of load for which the rating is being conducted (e.g., bending moment, shear, etc.); [n.sub.D] = number of dead load
comparisons; [n.sub.L] = number of live loads other than the rating vehicle; [[gamma].sub.Di] = dead load
factor in the ith dead load
; [[gamma].sub.Li] = live load factor for the ith live load other than the rating vehicle; [[gamma].sub.R] = live load factor for the rating vehicle; [L.sub.R] = nominal live load effect for the rating vehicle; and [m.sub.FLE] = factor to account for the significance of the overload to FLE.
(2002) conducted a numerical study on FA and PA walls carrying dead load
. They determined that PA walls carrying sufficient dead load
have strength similar to that of FA walls that are not carrying dead load
The additional dead load
applied to the floors accounts for items such as partitions, ceiling, mechanical ductwork, electrical items, plumbing, and so forth.
With this method, the bridge's dead load
is transferred through the rollers into the rack and then into the pivot pier as the bridge opens.
Main goal of defined procedure is to achieve desired shape of bridge deck under dead load
and to optimize the number of bearing and post-tensioning cables.
Many older homes weren't framed to handle that much dead load
. And new shingles just don't last as long over existing shingles due to the increased heat build-up in the mass of asphalt.
In general, locate the bolted field splices near the dead load
inflection points for continuous girders.
