Centrifuge modeling of rocking-isolated inelastic RC bridge piers. [PDF]
Earthq Eng Struct Dyn, 2014 Experimental proof is provided of an unconventional seismic design concept, which is based on deliberately underdesigning shallow foundations to promote intense rocking oscillations and thereby to dramatically improve the seismic resilience of structures.

Seismic strengthening of nonductile bridge piers using low-cost glass fiber polymers [PDF]
Bulletin of the Polish Academy of Sciences: Technical Sciences, 2020 Several recent earthquakes have indicated that the design and construction of bridges based on former seismic design provisions are susceptible to fatal collapse triggered by the failure of reinforced concrete columns.

Clear Water Scour at Rectangular Bridge Pier with Collar [PDF]
Port Said Engineering Research Journal, 2023 Scour is the most significant threat to waterways because it leads to the failure of bridge piers and other structural components. When a collar is put in place around the pier to lessen the direct effect of the downflow on the streambed, the maximum ...

Analysis of Mechanical Performance of Steel-Concrete Composite Girder Bridge with V-Shaped Piers
Advances in Civil Engineering, 2022 The steel-concrete composite girder bridge with V-shaped piers is a new type of bridge structure. It has both the unique mechanical performance of a combined continuous girder and that of a V-shaped pier bridge.

Investigation of scour around the dual bridge piers under unsteady flow conditions using experimental model [PDF]
Journal of Applied Research in Water and Wastewater, 2020 The local scour around the bridge piers is the main cause of their destruction. Based on this, extensive studies have been done to understand this phenomenon. Most of these studies have been done under steady flow conditions.

Experimental and Numerical Investigation of Local Scouring around Bridge Piers in Different Geometric Shapes at a 90° Convergent meander [PDF]
Journal of Hydraulic Structures, 2020 The presence of several convergent meanders is a basic characteristic of natural flowing rivers. It is important to construct bridge piers in different geometric shapes at convergent meanders.

Local Scour Around The Cylindrical Bridge Pier With Two Sizes of Bed Material [PDF]
علوم و مهندسی آبیاری, 2015 Local scour around the bridge piers results from the flow impact with bridge piers and it’s streamline separation. The scour hole around the bridge piers depend on the hydraulic characteristics of the flow, the specifications of the fluid, the pier’s ...
