Data for wetlandscapes and their changes around the world
(Copernicus Publications, 2020-05-13)Geography and associated hydrological, hydroclimate and land-use conditions and their changes determine the states and dynamics of wetlands and their ecosystem services. The influences of these controls are not limited to ... -
Diagonally Reinforced Concrete Coupling Beams: Effects of Axial Restraint
(American Concrete Institute, 2021-11)Two pairs of nominally identical large-scale coupling beam specimens were tested under reversed cyclic displacements. Within each pair, one specimen was free to elongate and the other had resistance to elongation during ... -
High-Strength Steel Bars in Earthquake-Resistant Reinforced Concrete T-Shaped Walls
(American Concrete Institute, 2021-01)Six large-scale reinforced concrete T-shaped slender walls were tested under reversed cyclic loading to study the effects of reinforcing bar mechanical properties on wall deformation capacity. Effects on lateral stiffness ... -
Strength and Deformation of Reinforced Concrete Squat Walls with High-Strength Materials
(American Concrete Institute, 2021-01)The behavior of reinforced concrete (RC) squat walls constructed with conventional- and high-strength materials was evaluated through tests of 10 wall specimens subjected to reversed cyclic loading. Primary variables ... -
Load Rating Reinforced Concrete Bridges without Plans: State-of-the-Practice
(American Concrete Institute, 2020-06-01)In response to Federal Highway Administration requirements, several states are in the process of ensuring all bridges within their inventories are load rated. A challenging aspect of this effort is load rating reinforced ... -
Diagonally Reinforced Concrete Coupling Beams with Grade 120 (830) High-Strength Steel Bars
(American Concrete Institute, 2020)Four large-scale coupling beams were tested under fully reversed cyclic loads to investigate the effects on behavior of diagonal bar grade (60 or 120 [420 or 830]), beam shear stress (9.5 or 14√fc′, psi [0.79 or 1.17√fc′, ... -
Girder–Deck Interface: Partial Debonding, Deck Replacement, and Composite Action
(American Society of Civil Engineers, 2019-01)Results are reported from tests of three precast, prestressed concrete girders under fatigue-type cyclic and monotonic loading conducted after deck removal and replacement. Although deck demolition altered the top surface ... -
Implementation of High-Performance Fiber Reinforced Concrete Coupling Beams in High-Rise Core-Wall Structures in the Seattle Area
