RISParametric Effects on Evaluation of an Impact-Damaged Prestressed Concrete Bridge Girder Repaired by Externally Bonded Carbon-Fiber-Reinforced Polymer Sheets
Publisher: American Society of Civil Engineers
Abstract: This paper investigates the evaluation procedure of an AASHTO Type 3 precast-prestressed girder that was extensively damaged by truck impact and then repaired using externally bonded fiber-reinforced polymer (FRP) composites. ...
Discussion of “Experimental Studies on Flow over Labyrinth Weir” by B. V. Khode, A. R. Tembhurkar, P. D. Porey, and R. N. Ingle
Publisher: American Society of Civil Engineers
Mixing of Twin Particle Clouds in Stagnant Water
Publisher: ASCE
Abstract: The interaction and mixing of twin particle clouds in stagnant water were studied by a series of laboratory experiments. The importance of source separation distance and sand particle mass was investigated by introducing ...
Effects of Secondary Current on the Local Erosion Induced by Circular Turbulent Wall Jets in Cross Flow
Publisher: American Society of Civil Engineers
Abstract: This paper presents the results of a series of laboratory experiments, by placing a turbulent wall jet in the upstream and downstream of a 90° channel bend, to investigate the effects of secondary flow on formation of local ...
Dynamics of Sand–Water Coaxial Jets in Stagnant Water
Publisher: American Society of Civil Engineers
Abstract: A series of laboratory experiments was conducted to study the dynamics of sand–water coaxial jets in stagnant water. The effects of the velocity ratio of the annular to the core jets on the sand concentration, velocity, ...
Discharge Characteristics of Weirs of Finite Crest Length
Publisher: American Society of Civil Engineers
Abstract: This technical note presents a critical analysis flow over weirs of finite crest length, with square-edged or rounded entrance, for free-flow conditions. Using the flow equation for the broad-crested weir with parallel ...
Experimental Investigation of One-Cycle Triangular Labyrinth Weirs with an Upstream Pool
Publisher: ASCE
Abstract: The hydraulic performance of triangular labyrinth weirs with an upstream pool was experimentally studied in both free and submerged flow conditions. The discharge coefficients based on channel width B and the weir length ...
Experimental Study of Particle Clouds in Stagnant Water
Publisher: American Society of Civil Engineers
Abstract: Laboratory experiments were conducted to investigate the evolution of particle clouds in stagnant water. Nozzle size and released mass of particles were formed to an aspect ratio of Lo/do, where Lo is a length of sand ...
Discharge Characteristics of Weirs of Finite Crest Length with Upstream and Downstream Ramps
Publisher: American Society of Civil Engineers
Abstract: This paper considers flow measurement in open channels with transverse weirs of finite crest length with sloping crests and upstream or downstream ramps—or both—for free flows. Using the broad-crested weir equation with a ...
Submerged Flows over Rectangular Weirs of Finite Crest Length
Publisher: American Society of Civil Engineers
Abstract: This work presents a critical analysis of submerged flow over rectangular weirs of finite crest length. For finite crest length weirs, because the existing data sets are not extensive, new experiments for these weirs with ...
