Progress in Hydromechanics
The historical development of hydromechanics in the fifty years since the founding of the Hydraulics Division is reviewed. Rouse's 1938 text, Fluid Mechanics for Hydraulic Engineers, provided...
Superstructure: Statics Discussion
This chapter briefly discusses the statics of the Colossus....
Transmission Line Insulator Assembly Reliability
Transmission line insulator assemblies made up of ceramic or composite insulators and associated hardware are used to mechanically support and electrically isolate energized conductors...
Analysis of the Non-Planar Response of a Cantilever, with the Aid of Computerized Symbolic Manipulation
The nonlinear differential equations governing the static deformations of a cantilever with a tip mass are formulated and analyzed with the aid of computerized symbolic manipulation. The...
Neural Network Approaches in Structural Mechanics Computations
The neural computing paradigm has not been extensively researched in terms of its applicability to a wide variety of structural engineering problems. At an intellectual level this research...
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...
Optimization of Cable Prestresses of Cable Stayed Bridges Based on Minimum Strain Energy Criterion
In this study, an attempt is made to determine the optimum cable prestresses based on the strain energy criterion. The validity of the strain energy criterion on the optimum cable prestresses...
Two-Level Optimization of Nonlinear Structures
This paper presents several optimization design problems and their applications to both cable structures and geometrically nonlinear braced-rib arches. The sum of squares of residuals...
Experience with the p-Version Program PROBE
The conventional approach in the FEM is known as the h-version, in which the solution accuracy depends on the size h of elements. The alternative approach is the p-version, in which the...
Application of BEM to Two-Dimensional EPFM
This paper describes the authors' current and continuing research in application of the Boundary Element Method (BEM) to crack growth problems in Elastoplastic Fracture Mechanics...
Behavior of a Crack Under Reversed Cyclic Loading
The results of two series of basic experimental studies for opening and closing behavior in RC members are reported. For the first series, axial forces were applied to the specimens in...
Fourier Series Expansion on Determination of Response Bound of Beam
Fourier series expansion is suggested to discrete the continuous vibrating system by regarding Fourier constants as generalized displacement parameters. The orthogonal merit to the terms...
Analysis and the Design of Multi-Layer Viscoelastic (V.E.) Dampers for Tall Structures
Vibrational motion of tall buildings can be damped by employment of viscoelastic passive dampers in the structure. The type of dampers selected depend on locations where relative displacements,...
Unsteady Aeroelastic Base Moments on a High-Rise Building
To consider aeroelastic instabilities of prismatic structures in winds, i.e., vortex induced vibrations or galloping oscillations, unsteady aeroelastic forces must be investigated as the...
Reliable Displacements from Integrated Quick-Release Accelerograms
A new baseline correction method has been developed which allows accelerograms collected during quick-release tests of full scale structures to be doubly integrated to displacements. The...
Deformability of Reinforced Concrete Members
A large volume of test data has been evaluated to establish deformability of reinforced concrete beams, columns, and structural walls in the inelastic range. Experimentally observed deformation...
Tension Leg Platform
a State of the Art Review
Prepared by the Task Group on Compliant Offshore Platforms of ASCE. This report considers the analysis and design of tension leg platforms (TLPs),...
Rock Excavations in Downtown Toronto
The geology of Toronto area is somewhat complex due to the series of advances and retreats of the glaciers. The overburden deposits consist of materials laid down during the Wisconsinan...
On the Critical Relative Displacement of Pile Shaft and Surrounding Soil
Model pile pull-out tests have been conducted to investigate the characteristics of the critical relative displacement at which the critical pile skin resistance is mobilized. Test results...
Settlement of Strip Foundations on Regularly Jointed Rock Masses
The analysis of a long, rigid strip foundation resting on the surface of a regularly jointed rock mass is presented. Two models of the overall rock mass are investigated; one in which...
