Advancements in Aerodynamics, Fluid Mechanics and Hydraulics
The theme of these Proceedings is Advancements in Aerodynamics, Fluid Mechanics, and Hydraulics. As indicated by the title, the subject crosses disciplinary boundaries and deals with flow...

Hypars and Wood Shells?The Boston College Recplex
For the past twenty years, we have been involved in the design and construction of intermediate span wood hyperbolic paraboloid. During that time the spans have ranged from 50 ft. to 200...

Nonlinear Quasi-Static and Transient Response Analysis of Shallow Shells: Formulations and Interior/Boundary Element Algorithms
Nonlinear integral equations are derived for the representation of displacements of shallow shells undergoing moderately large, quasi-static or dynamic deformations. A combined interior/boundary...

A Study on Non-Conforming Boundary Elements in Elastomechanics
This work is a critical study on the performance of non-conforming boundary elements in three-dimensional elastomechanics. The pervasive way of implementing the boundary element method...

Connection Panel Zone Deformation in Steel Frames
Conventional analyses of frameworks are usually carried out without considering the effect of panel zone deformation on frame behavior. As a result, center-to-center distances rather than...

Avoiding Cracks in Brickwork
Many aspects of movement and differential movement have been discussed. However, other movements and effects of movement that have not been discussed may also affect the performance of...

A Mesh Generator for the Modeling of Rock Discontinuities
The need to characterize a rock mass by collecting field data is receiving more and more emphasis as larger, more ambitious underground structures are being built. Yet there is a need...

Super and Parallel Computers and Their Impact on Civil Engineering
This publication contains four papers on the use of super and parallel computers in the practice of civil engineering. The first paper shows how large nonlinear systems of equations, such...

Designing for Shock Resistance
If a product or structure is subject to shock loadings, and is unable to take them without unacceptable damage, it must be insulated from the shock. The decision may be to redesign the...

Frame Moments with the Takabeya Method
The Takabeya method of frame analysis, based on the same slope-deflection equations as the Hardy-Cross system, has the advantage of requiring much less memory and fewer computations than...

Creep Properties of Ice: Theory and Experiment
In recent years, intensive developments in Northern regions have increased the demand for solutions to a large number of engineering problems involving ice mechanics. In particular, these...

Triaxial Compression Testing of Ice
An understanding of the confined compressive strength of ice is needed to develop constitutive equations and failure criteria for analytical ice-structure interaction models. Procedures...

Constitutive Equations for Ice as a Damaging Material
Constitutive equations for ice subjected to uniaxial compression are developed based on applications of the theory of continuous damage mechanics. A physical model of ice deformation response...

A Hybrid Structural Ice Defense Mechanism
A hybrid plate composed of steel outer surfaces and a concrete core has characteristics that make it desirable for use on offshore structures in ice prone environments. The service and...

Multi-Truss Design for Tower
A modified structural steel system of outrigger trusses and belt trusses bolster the 54-story Equitable Tower West. Located in New York City, the building's structural system...

Application of Displacement of Discontinuity Methods in Underground Mine Design
Displacement discontinuity methods for stress analysis, pioneered by Starfield and Crouch (see, for example, Starfield and Crouch, 1972; Crouch, 1976; and Crouch and Starfield, 1983),...

A Combined Limit Equilibrium and Statistical Analysis of Wedges for Design of High Rock Slopes
This paper describes a unique technique developed for the statistical analysis of wedge failures which control the design of high slopes in relatively hard jointed rock masses. Using this...

Fracture and Fragmentation of Rock Materials by Explosives
Explosives are used in various commercial applications including the extraction of natural resources from the earth and removal of materials for new construction. These applications include...

Modelling of the Fracture Process Zone in Rock
There are a number of situations in the fracture mechanics of rock in which linear elastic fracture mechanics (LEFM) concepts are inapplicable or insufficient. Two such situations are...

On the Design of Continuous Composite Beams
Methods of analysis and design of continuous composite beams are presented. Numerical analysis is used to determine the effective width of the slabs to be used in design. The influence...
