Uncertainty of Local Scouring Parameters Around Bridge Piers
local scour bridge pier reliability uncertainty
2009/10/13
Reliability-based assessment of local scouring mechanism around bridge piers provides information for decision-making regarding the pier footing design. Parameter uncertainties that may arise from var...
Generalized Reliability Model for Local Scour around Bridge Piers of Various Shapes
Reliability bridge pier scour pier shape resistance loading safety factor return period
2009/10/13
Excessive local scour around piers and abutments is known as a major cause of bridge failure induced by hydraulic de ciencies. Complexity of the scouring phenomenon and high degrees of uncertainties i...
A STUDY ON FORCE-DISPLACEMENT-BASED SEISMIC DESIGN OF SINGLE-COLUMN RC PIERS
acceleration-displacement response spectrum modified Park-Ang damage index
2008/12/29
As a fundamental study to develop a force-displacement-based seismic design of RC piers, the acceleration-displacement response spectrum (ADRS) of SDOF systems with elastic-plastic bilinear restoring...
EXPERIMENTAL STUDY OF REINFORCED CONCRETE BRIDGE PIERS SUBJECTED TO BI-DIRECTIONAL QUASI-STATIC LOADING
bi-directional cyclic loading RC column members plastic hinge zone length energy dissipation
2008/12/26
This research aims to determine the effect of loading pattern on the damage of a reinforced concrete bridge column. Five specimens were tested with uni-directional or bi-directional cyclic loading pa...
TWO-LEVEL SEISMIC DESIGN METHOD USING POST-YIELD STIFFNESS AND ITS APPLICATION TO UNBONDED BAR REINFORCED CONCRETE PIERS
post-yield stiffness two-level seismic design UBRC structure small section pier
2008/12/22
The two-level seismic design method using post-yield stiffness is proposed. The post-yield stifiness on the load —displacement relationship of the RC pier is found to be effective for the reduction o...
