Noise and Air Blast from Construction Blasting
Noise generated by construction blasting differs from other construction noise because of its frequency content. The audible high frequency portion is accompanied by a non audible, lower...
Cost Assessment of Construction Noise Control
The results of a series of studies have provided noise control engineers with a method to estimate off-site construction noise levels and the cost of reducing these to acceptable levels....
Noise Assessment, Measurement, and Mitigation, an OSHA View
A discussion is presented on the Occupational Safety and Health Administration (OSHA) 29 CFR 1910. 95 General Industry noise exposure standards and the 29 CFR 1926. 52 and 1926. 101 Construction...
Can Clay Liners Work?
Nearly all liners for landfills and surface impoundments were constructed from compacted clay until about five years ago. But this is no longer so. In the past few years, clay liners used...
Municipal Refuse: Is Burning Best?
Communities are increasingly worried about polluting groundwater, and it is increasingly difficult to get permits to start new landfills. For these reasons, there is a trend back to municipal...
Hammering Out a New RCRA
Recent amendments to the Resource Conservation and Recovery Act (RCRA) add thousands of new waste generators and many new wastes to the list of those to be regulated. Some say RCRA is...
A Tale of Six Cities
Battle Creek is a four mile urban stream that had an erosion problem that was accelerating with urbanization of its watershed. Erosion created unstable ravine slopes over 60 feet high,...
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...
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...
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...
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 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...
Bond Stress of Embedded Steel Shapes in Concrete
This paper describes an investigation into the bond stress developed between steel shapes and reinforced concrete when the concrete is lightly stressed. A brief discussion of previous...
Recent Developments for Composite Buildings in Japan
Research work and construction practice of composite steel and reinforced concrete structural systems in Japan are reviewed, based on the data gathered by the working group of the Architectural...
Composite Columns?Design and Examples for Construction
The new German standard DIN 18806, part 1 gives the rules for the design of composite columns. The general method, taking into account all the inhomogeneties of the two materials steel...
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...
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...
Civil Engineering in the Arctic Offshore
