Around the Bend
An architecture firm envisions an inverted U-shaped tower in New York City that would outstrip the height of current megatall structures and replace it with length....
Performance Limits for Deepwater Pipelines
This paper highlights the differences between onshore and offshore pipeline design. It then summarizes the results of combined external pressure, tension, and bending testing on full scale...
Real-Time Control for a Robotic Rebar Bender
Job conditions and variability in the properties of the stock material combine in a rebar bending operation to create a challenging environment for a robotic bender. This paper reports...
ATLSS Connections with Moment Capacity
ATLSS Connections are a family of beam-to-column connections which utilize the self-aligning feature of a specially designed connector and are developed for possible use in an automated...
Proposed Test Method for Determining Bending Yield Moment of Nails
Current engineering design procedures use a yield theory to establish the nominal resistance (capacity) for laterally-loaded nailed connections in engineered structures. In order to develop...
Spatial Structures Erected out of Thin Shell Elements Fabricated on Plane Followed by Bending
The paper offers the examples of spatial structures of average spans (up to 24 m) and engineering structures made of prefabricated curvilinear elements originally having a plane form....
Calibration of Movable Bed Model for Armant Area
The morphology of the Nile River, in Egypt, is undergoing continuous changes which causes navigation bottle-necks in some local reaches. About 200 km downstream Aswan, at Armant area,...
Ice Accumulation Rate and the Geometry of Ice Jams in River Bends
Experiments on development of ice jams in river bends were performed in a 2.60-m-wide bend flume with a sand bed and 5-mm-diameter plastic beads simulating ice particles. The ice particles...
Two Full-Scale Tests of Class 3 Composite Beams
This paper presents two tests of continuous composite beams comprising two 7.5 m spans and two concentrated loads close to the intermediate support. Although the cross-sections on the...
A Shear Locking Free Three-Node Triangular Plate Bending Element for Moderately-Thick and Thin Symmetrically Cross-Ply Laminated Plates
A shear locking free three-node triangular plate bending element based on Reissner/Mindlin theory for symmetric general cross-ply laminated plates is developed. The element has total nine...
Experimental Investigation of Bending and Twisting Coupling in Thin-Walled Composite Beams
The behavior of a thin-walled ppen section composite material beam depends on the anisotropic mechanical properties of the panels that form the beam. A beam theory has been proposed for...
The OCEA Awards of Merit
Submerged rock weirs help tame the Mississippi River, high head pump storage provides power to a community safely and inexpensively, and the world's largest cantilevered hangar...
Safe-Load-Limit of Plates in Cylindrical Bending
The derivation of a closed-form expression for the viscoelastic critical load of long thin plates undergoing cylindrical bending and made of a linear time-dependent 'solid'-type...
Elastic Stability of a Laminated Column
Buckling load of an unsymmetric, laminated column is obtained through the use of imperfection method. The condition requiring to have non-vanishing bending moment at the ends of a pinned-pinned...
Relationship Between Scour Depth and Bend Radius of Curvature on the Red River
Studies of bank and bend processes were undertaken on the Red River between Index, Arkansas and Shreveport, Louisiana in connection with the navigation project on the river downstream...
Fiber Reinforced Plastic Grids for the Structural Reinforcement of Concrete
The use of fibre resin plastic grid is investigated as a primary bending reinforcement in concrete members. Laboratory bending data is compared with theoretical results using ACI 318-83...
Bed Topography and Sorting in Alluvial Channel Bends
A quasi-three-dimensional model has been developed for the purpose of calculating the velocity distribution, the bed topography and sediment sorting along channel bends. The depth-averaged...
Riprap Stability in Channel Bends
A systematic test series is underway in a large test channel to define the stability of riprap on the outer bank of channel bends. A 'practical equilibrium' concept...
The Lower Mississippi River and the Coriolis Force
Weather patterns and large bodies of water respond to the forces generated by the earth's rotation. A large north-south flowing river, such as the Lower Mississippi River,...
Instream fFlows for the Big Bend Reach of the Platte River
The Big Bend reach of the Platte River in Central Nebraska provides habitat for 230 species of migratory birds. Included are six endangered or threatened species and the world's...
