The flow modes and the length of the recirculation zone behind P1 (KP1) and P2 (KP2) in different cases are shown in Table2. The recirculation zone is the complete negative flow ve...
Guide This post describes different type of pier foundations used for bridge structure and how to select a suitable type of pier for a bridge.
Guide This paper numerically investigates the flow velocity performance around tandem double round-ended piers by performing a flow field model and moving ship model.
Guide The piers supporting a bridge which spans a river are constructed in the following way. Oversize screws, arranged in a row at right angles to the direction of the flow of the river, are screwed...
Guide This paper proposes an innovative double-limb-thin-wall (DLTW) bridge pier, which consists of two thin-limb-wall columns in the longitudinal
Guide Bridges with double-column high piers are mostly used in mountain areas. This kind of bridge can adapt to complex landform. But the double-column high piers have weak anti-impact capability, which are
Guide Recently, the authors introduced a parameter-adjustable cable-pulley based self-centering energy dissipation (CP-SCED) brace to mitigate seismic induced damage of reinforced
Guide This document provides guidance on designing bridge piers supported by pile foundations according to AASHTO-LRFD specifications. It describes calculating
Guide To mitigate the rockfall hazard to the bridge, a new flexible, energy-dissipating crashworthy device for bridge piers is developed to withstand the
Guide A bridge pier is a type of structure that extend to the ground below or into the water. It is used to support bridge superstructure and transfer the loads to the
Guide To investigate the seismic performance of reinforced concrete (RC) double-column piers, particularly unequal-height double-column piers under the combination of compression, bending,
Guide Substructure consists of bridge pier, abutments, wing walls, piles etc. while the superstructure consists of deck, girders or any part on which the traffic
Guide The re-centring ability and durability of important bridges have been the main objectives in recent provisions of seismic design codes. To achieve better recoverability and durability for piers,
Guide The stiffness center and mass center of the unequal-height double-column piers do not coincide in the longitudinal direction of the bridge. Furthermore, curved bridges, skewed bridges and
Guide ree-line ship lock on the Xiangjiang River as an example. Model tests and numerical simulations were conducted. The results indicate the following: The morphology of the active sliding fracture surface
Guide Finally, the effectiveness of CFRP shear-strengthening of double-column RC bridge piers to resist the lateral consecutive impact is studied. The present work can provide the benchmark test data for
Guide The superstructures of the bridges are generally supported by means of rigid attachment to the piers, roller or sliding bearings, or neoprene pads. Neoprene pads, as used in Pont Aval, are a very simple
Guide Unlike single-column piers, double-column piers exhibit different seismic performance characteristics in the transversal and longitudinal directions, especially irregular double-column
Guide If we were going to span a "deep canyon" with a series of Kato (n-scale) double track truss bridges, what would folks recommend for us to use for piers to get sufficient height?.... The
Guide Pier Design Example Obtain Design Criteria Design Step 8.1 Commentary for 1: Includes: Concrete strength, Concrete density, Reinforcing steel strength, Superstructure information, Span
Guide Coupling beams are used in double-column high-pier bridges to improve the integrity of the two piers. The stiffness of coupling beams has a significant effect on the seismic performance of
Guide Numerical simulations are employed to model the foundation pit and analyze the stress distribution and deformation of double-row retaining systems with T-shaped, cross-shaped, or square
Guide To improve the local scour protection of the pier using solid sacrificial piles, a kind of permeable sacrificial pile filled with stones is put forward in this study.
