The hydraulic fracturing containment problem is the subject of the present investigation. Unlike previous studies, the interface crack geometry with the correct crack tip singularity was...
Cost-Effective Design of Practically Vibration-Free High-Technology Facilities
Advanced electro-optical equipment, such as that used in the production of integrated circuits, requires clean environments with extremely limited vibrations. Ground motions, personnel...
Site Selection and Building Design for Minimizing Vibration
Over the last five to ten years, line resolutions required for state-of-the-art semi-conductor wafers have dropped to well below 1 micron. As a result, controlling environmental building...
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...
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...
Load-Carrying Capacity and Remaining Life of First-Built Composite Girder Bridge in Japan
Kanzaki Bridge, Osaka, Japan, was the first steel-concrete composite bridge built in 1953 to carry the Osaka Prefectural Road over Kanzaki River. The bridge was removed in 1978 after 25...
Dynamic-Fatigue Response of Continuous Composite Bridges
The dynamic response of continuous composite bridges and the influence of fatigue loading at resonance frequency on the structural response are investigated. It is shown that cracking...
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...
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...
Shear Strengths of Concrete-Filled Steel Box Elements
This study evaluated the ultimate strengths as well as the effect of the ultimate composite actions of concrete-filled steel composites under combined bending, shear, and axial forces....
Seminar Summary and Research Needs
All the papers presented in the technical sessions of the seminar are summarized and, in some cases, commented upon. The needed research in composite and mixed construction is described....
Reshaping the Future of Plastic Buildings
Plastic structures have been around for 40 years, but have for the most part been showcases with little use in the mainstream of the building industry. To be used effectively, plastics...
New Pavement from Old Concrete
Recycling portland cement concrete has gained momentum as an alternative to resurfacing aging highway and airfield pavements. Recycling cuts down rawmaterial requirements, reduces the...
Building on Muck
The Craney Island Disposal Area at Norfolk, Va. is a 2,500 acre depository for material dredged from ports and channels in the Hampton Roads. The U.S. Army Corps of Engineers extended...
Quality in the Constructed Project
The purpose of the workshop summarized in this book was to develop an agenda for ASCE actions to promote quality in the constructed project. The papers, discussions and session reports...
Rebuilding America
Infrastructure Rehabilitation
The future of the nation demands a solution to the problem of our deteriorating infrastructure. Civil engineers are called on to act as guardians of our public works facilities that must...
The National Ground Water Information Center Data Base
The Research Institute, Education Foundation and Publishing Company of the National Water Well Association have long been considered information central for the world's community of hydrogeologists....
Integrated Design Methodology for Urban Stormwater Detention Facilities
The objective of this paper is to present the core of a design methodology that avoids the pitfalls of the design storm concept by using a microcomputer algorithm to estimate the long-term...
Personnel Policies for Operations Management in the Computer Age
