Sentence examples for straight bridge from inspiring English sources
Backfill pressures were consistent across the abutment in the straight bridge, but highly variable in the 15° skew bridge.
Benchmark skew and straight bridge models were designed with both EDSs and analyzed using nonlinear time history analysis method to examine their seismic performance.
It's the ultra-right and it's also a straight bridge with the Front National in terms of identity and the idea of the family".
This study aims to close the knowledge gap through a series of shake table tests performed on a straight bridge, 30° and 45° skewed bridge with abutments on either side of the bridge structure.
Previous research has found that skewed bridges are more prone to girder unseating than a straight bridge due to the in-plane rotations of the bridge girder which were found to be aggravated by pounding between adjacent spans and abutments.
With a 10° skew and 0.06 radians arc span length to radius ratio, the curved and skewed integral abutment bridges can be designed as a straight bridge if a 10% increase is applied to the total induced stresses.
However, deck rotation in straight bridges has been identified as an unusual failure mode.
Most computational research related to steel bridge seismic vulnerability has focused on statistical extrapolation of analysis results for individual straight bridges.
Through extensive nonlinear time-history analyses conducted using three suites of ground motions, it is demonstrated that demand parameters for skew-abutment bridges, such as deck rotation and column drift ratio, are higher than those for straight bridges.
Moreover, with variation in the nose length ratio, the value ln/l = 0.60 with respect to the span length, is confirmed as the optimal value, as happens for straight bridges.
Although it has mainly been applied to straight bridges with box sections, today it is also used for construction of horizontally curved bridges with concrete and composite steel concrete closed or open sections like I-girders.
