Structural Expression in Tall and Super Tall Buildings
The economic and social pressures that have pushed skyscrapers higher above our cities have also brought forth new structural systems for tall buildings. As this trend is expected to continue...
Installation of Category I Caissons
Founding a proposed safety-related Category I structure of a nuclear power plant on rock socketed caissons necessitated using precision installation techniques. These techniques were chosen...
Managing Quality into the Workplace
In February, 1983, the author's organization began a process designed to enhance attitudes about quality in every individual member of the organization. The process requires...
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),...
Application of a Three-Dimensional Coupled Finite Element?Boundary Element Method
Three-dimensional conditions in underground construction occur at the face of a tunnel, at intersections of underground openings and around roughly equidimensional openings. As long as...
An Application of Probability to Rock Slope Design
This paper describes the use of probability and statistics in the slope design process. An example is presented of a high rock slope in an open pit mine. This slope is a major concern...
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...
Probability Applied to Slope Design?Case Histories
A major problem encountered with the choice of an appropriate value for the design probability. Initial experience, obtained during open-pit investigation, suggested that slope geometry...
Hundreds of Bridges�Thousands of Cracks
In the past 10 years hundreds of welded steel bridges, most of them relatively new, have suffered thousands of cracks due to secondary stresses, that is, the cracks are caused by deflections...
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...
Behavior and Strength of Stub-Girder Floor Systems
The paper presents a detailed evaluation of the behavior and strength characteristics of the stub-girder floor system. This is a composite girder and beam structure that integrates the...
Proposed Design Criteria for Composite Steel Deck Slabs
Composite steel deck slabs have continued to gain popularity; today they are one of the predominant means of floor slab construction in most typical buildings. The term 'composite...
Design and Testing of a 400 Ft Span Plate Girder Bridge
The paper describes design features and testing of the Madawaska River Bridge. The bridge is unique in being the longest span plate girder bridge in Ontario, having continuous spans of...
The Eurocodes and Shrinkage in Composite Beams
The two parts of this paper relate to different aspects of design procedures for composite structures of steel and concrete. First, recent developments in the coordination of the eight...
Experimental Investigation of Composite Rigid Frames
According to the series of tests conducted by the authors on composite rigid frame models, the compressive principal stress in the steel web plate at the corner panel was considerably...
A History of Adhesive Bonded Composite Members
The history and development of adhesive bonding in composite members is traced. Two forms of composite members are explained. Research from different parts of the world is compared. Applications...
Mixed Systems: Past Practices, Recent Experience, and Future Direction
A comparison is made between composite column capacities derived from the authors procedure utilizing the ACI (America Concrete Institute) code requirements, and previously published semi-empirical...
Recent Research on Composite Structures for Building and Bridge Applications
Continuing research has been carried out at Lehigh University on composite structural members, joints, and overall systems. This paper summarizes the results of research on four selected...
SRC Elevated Station Structures for New Bullet Trains
SRC Steelframe reinforced concrete structures were utilized on several station buildings for the Japanese National Railways bullet trains. This paper presents an outline of the dimensions...
Recent Developments in Mixed Steel-Concrete Systems
Mixed steel-concrete systems have emerged into a well established new system that can be used as readily as either steel or concrete systems for high-rise buildings. Mixed systems offer...
