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...

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...

Composite Bridge Design in Germany
A span length between 40 m and 12 m has been regarded as optimal up to the mid-60's for a composite design to compete with prestressed concrete or steel alternatives. With...

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...

Seismic Capacity Evaluation of SRC Buildings
The Japanese standard for seismic capacity evaluation of existing composite steel and reinforced concrete (SRC) buildings was introduced. As it developed, based on the previously established...

Composite and Mixed Construction in Czechoslovakia
Various composite and mixed systems have been used in Czechoslovakia. Special attention is focused on design methods, effective construction, and material savings. Current developments...

Seismic Strengthening of Existing RC Buildings
Seismic strengthening of existing reinforced concrete (RC) frame buildings by the use of steel braces or panels was studied experimentally. A special joint between steel elements and the...

Checking Off CADD Priorities
Diving head on into new computer aided design and drafting (CADD) hardware and software without considering their effects on firm or university's operation is as bad as ignoring...

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....

Implementation of a Micro-CADD System
Computer-aided-design-and-drafting (CADD) systems utilize computer technology to aid the engineer in his work. CADD systems are designed to process graphics with speed and accuracy to...

Water Distribution Design with Multiple Demands
An iterative procedure for the layout and design of new looped water distribution systems is pesented. The procedure is also applicable to the expansion of existing systems. The approach...

Practical Optimization of Looped Water Systems
This paper describes one tool that might be part of a package to assist a design engineer in sizing pipes, determining ideal locations for booster pumps and their heads, determining heads...
