Optimal Design of Arches Using the Complex Method
Optimal designs of arches under multiple load cases using an automated design routine are presented. The design variables consist of geometric (arch shape) as well as member sizing variables...

Airborne Laser Acquisition of Cross-Section Data

Nonlinear Dynamics of Tube in Coaxial Flow
This note describes such as investigation in a relatively simple case. The structure is treated as a simply supported Euler beam of circular cross section with a fixed distance between...

Torsional Rigidity of Partially Yielded I-Sections
Steel beam-columns of I-shaped cross section commonly collapse in a flexural-torsional mode. The St. Venant torsional rigidity is therefore one of the relevant section properties in analysis....

Minimum-Weight Design of Nonuniform Beams
This note reports the results of an investigation of the minimum-weight plastic design of a propped cantilever beam of nonuniform cross section. The design of a propped cantilever occurs...

Supercritical Flow in Bends of Trapezoidal Section
Steady supercritical flow in circular bends of trapezoidal cross section is analyzed for the case in which the radius of curvature r0 of the center...

Variations in Dimensions of Reinforced Concrete Members
Variations in cross-sectional dimensions and in the location of reinforcing bars in slabs, beams, and columns are reviewed. Normal distributions are proposed for these quantities. The...

Hydraulic Resistance of Artificial Strip Roughness
An experimental study of two-dimensional flow over non-uniform roughness is reported in which artificial strip roughness was employed. The roughness elements were square in cross section...

Inelastic Section Response by Tangent Stiffness
A review of inelastic analysis of a cross section is made. Given the history of deformation, the history of axial force and moment may be obtained. Also, given the history of moment and...

Pipelines — Positioning and Survey Problems
The first section of the paper describes the goals and objectives and some typical surveying problems encountered in the planning stages and, similarly, in the next two sections, design...

User Cost Analysis in Urban Freeway Rehabilitation
Based on the principles and techniques given in the 1977 AASHTO Manual on User Benefit Analysis for Highway and Bus Transit Improvements a...

Multiple Jets in Shallow Flowing Receiving Waters
An experimental study of multiple submerged heated jets discharging into confined, shallow, flowing receiving waters was conducted. Empirical relationships describing jet spreading and...

The Buckling of a Nonuniform Column

Effect of Side Slopes on Concrete Bearing Strength
The problem of large forces acting over limited contact areas of concrete is one of frequent occurrence in engineering deign. In three earlier papers, the effect of several important variables...

Effect of Channel Meanders on Flood Stage in Valley
Results of this study indicate that for a meandering channel in a valley there is an interaction between the channel flow and valley flow. The nature of the interaction varies with stage,...
