Design Considerations for Wind Loadings
The application of reliability concepts to the treatment of wind loadings on structures has increased in the past several years. Advances have been made in assessing the various uncertainties...

Seismic Probabilistic Risk Assessment for Critical Facilities
Probabilistic Risk Assessment (PRA) for seismic events is currently being performed for nuclear power plants. The background on seismic PRA is presented along with a basic description...

Bridge Inspection by Dynamic Loading Technique
This paper describes, a case study of the evaluation of the structural integrity of a New York State Thruway bridge using the dynamic loading technique. The study was undertaken in a effort...

Aesthetics of High-Rise Building Structures
The structural aesthetics of high-rise buildings is discussed, with particular emphasis on building frames, individual members and on joints and connections. Examples are given of towers...

Effects of Scale on Tall Buildings
The laws of scale in relation to structures are explored within an historic, as well as an aesthetic context. Particular emphasis is placed on the development of structural systems for...

Aesthetics and Design of Prestressed High-Rise Buildings
This paper will address the aesthetics, economic and construction-related advantages of prestressed concrete for high-rise buildings, with an emphasis on the South-East Asia region. While...

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...

Probability of Stability Design of Open Pit Slopes
Uncertainty and risk have always been associated with mining. This is evidenced in the common mining terminology of proven ore, probable ore, and possible ore. From a geotechnical standpoint,...

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...

Soil Nailing Supports Excavation
Excavation for the PPG Headquarters complex in Pittsburgh, Pa. was critical because the site is adjacent to three historically important buildings. Soil nailing, a method of in situ earth...

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...
