Riprap Stability Results from Large Test Channel
Velocity data from a large test channel were used to determine the distribution of depth-averaged velocity and shear stress on the side slope of both straight and curved channels. From...
Pressure and Stress Distributions Due to a Submerged Impinging Jet
This investigation examines the pressure and shear stress distribution at a smooth planar boundary in the impingement region of a submerged vertical jet in water. The mean pressure and...
Secondary-Flow Correction for Depth-Averaged Numerical Models
An empirical equation is proposed for the production and transport of secondary (streamwise) vorticity induced by lateral curvature in shallow water. The streamwise vorticity creates a...
Application of Weakly Compressible Flow Method to 2-D Open Channel Flows
The depth averaged equations for open channel flows are shown to be similar to that of the weakly compressible flows. The finite volume scheme developed for weakly compressible flows has...
Geomorphic and Sedimentologic Evaluation of a Proposed Flood Control Project, Truckee River, Reno, Nevada
Geomorphic observations, sediment data and shear stress analyses were integrated to evaluate the potential responses of the steep, coarse grained Truckee River to a proposed flood control...
Instability of Water-Fluid Mud Interface
Erosion and entrainment of fluid mud are treated by means of shear flow analysis. The water-fluid mud system is considered as a layered system of two continua separated by a distinct interface...
Reliability Assessment of Wood Components
Considerable progress has been made in the nondestructive evaluation (NDE) of wood components since the introduction of the first concepts more than twenty-five years ago. New stress wave...
Iterative Global/Local Finite Element Analysis
In spite of the advances in computer technology, there is still a need for more computationally efficient methods for performing stress analysis. One approach which is receiving increasing...
A Microplane Constitutive Model for Soils
A microplane model for the inelastic behavior of soils is presented. The microscopic constitutive equations are defined independentely for a set of microplanes covering all possible orientations,...
Geocomposite Waste Cell Capping System for Steep Slopes
Several geosynthetics manufacturers have developed new products with high surface friction characteristics for capping steep slopes. One such product has been developed that will satisfy...
Anomalous Structural Size Effect in Cohesive Materials Like Concrete
This contribution analyses on theoretical grounds the size effect trends in special cases where - unlike most experimental situations in fracture research - the specimen is not precracked...
Effects of Fabrication on Local Stress Conditions
Factors connected with fabrication that impact on the behavior of structural steel members are reviewed. Residual stresses that result from basic steel production and subsequent fabrication...
Effect of Imperfections on Structural Performance
This paper briefly describes the effect of initial crookedness and residual stress on the behavior of steel members. Both imperfections are unavoidable consequences of modern fabrication...
Local Buckling Behavior of Plate Elements
In the elastic post-local buckling range, the stress distribution across the width of compression elements of light gauge steel shapes is nonlinear. For code implementations, these stress...
Behavior of Cold-Formed Steel-Concrete Composite Beams
An experimental investigation was conducted at California State University - Long Beach to study the structural behavior of composite beams made of thin-walled cold-formed steel stiffened...
Strength of Biaxially Crooked Jumbo Columns
The ultimate strength of axially loaded jumbo columns with biaxial initial out-of-straightnesses is analyzed by the finite element method. The analysis makes use of the measured residual...
A Study of the Precision of Optimum Design Using Suboptimization
As the scale of structures becomes larger and their configuration become more complicated, the design variables and constraint conditions increase, and numerical calculation of the optimum...
Stress Computations for Nearly Incompressible Materials
Computation of stresses by the finite element method (FEM) in the case of nearly incompressible isotropic elastic materials is discussed. It is shown that for moderately high Poisson's...
Optimizing the Design of High-Rise Steel Buildings
The approximate stiffness method is utilized for a proposed procedure to evaluate the stiffness of the various frames and the stiffness of the members within the frames to provide a drift-controlled...
High Strength Concrete: Proportioning, Behavior and Applications
Generally, concrete with a cylinder compressive strength higher than 6000 psi (41.4 MPa) is designated as high strength concrete. High strengths are achieved using stronger coarse aggregates,...
