Corrosion Model for Concrete Structures
The high basic environment created by concrete pore water protects the reinforcing steel from spontaneously corroding. Chloride ions destroy the passivity of steel in concrete and the...
Reliability Assessment of Concrete Pavement Sawing
Traditional concrete pavement design sometimes realize on qualitative decision based on experience, with concrete pavement sawing operations representing a specific case in point. presently,...
Infrastructure Repair with Polymer Composite Using Recycled Plastics
Recycled poly(ethylene terephthalate), PET, mainly recovered from plastic beverage bottles, can be used to produce unsaturated polyester resins. Polymer concrete (PC) made with these resins...
The NOAA Restoration Center: Next Steps
The National Oceanic and Atmospheric Administration (NOAA) Restoration Center (RC) was founded in 1991. Since its inception it has made significant progress along several fronts. Foremost,...
Project Performance: Ocean City, Maryland Beach Nourishment
Detailed monitoring of the performance of a two-phase beach nourishment project has provided valuable information on beach fill behavior and long-term response of a beach fill to prevailing...
Application of Composite Members to Marine Structures in Japan
Composite structures combined steel plates and reinforced concrete with shear connectors have been applied to port and harbor facilities in Japan since the early 1980s.Composite structures...
Composite Construction?Recent Past, Present and Near Future
The present paper covers a shorter time span. It is divided into three parts: recent past, present and near future. The remarks regarding the recent past are limited to my personal experiences....
New Developments in Eurocode 4
The European Community has initiated the preparation of a set of harmonized structural codes. Eurocode 4 is the code for the design of composite steel and concrete structures. The first...
New Canadian Provisions Related to the Design of Composite Beams
In this paper, the new provisions in CAN/CSA-S16.1-M89 for the design of composite beams, together with reasons for changes, are discussed. Some of the new provisions reflect results of...
Composite Beams: Redistribution, Reliability, and Lateral Buckling
Research relevant to three aspects of the design of composite beams for ultimate limit states is summarized. These are: the redistribution in continuous beams and in framed structures...
Two Full-Scale Tests of Class 3 Composite Beams
This paper presents two tests of continuous composite beams comprising two 7.5 m spans and two concentrated loads close to the intermediate support. Although the cross-sections on the...
Shear Connection in Composite Beams
This paper considers the influence of the shape of the deck profile on the shear connection of composite beams. It was found that the existing strength reduction factor can be unconservative...
Serviceability Stress Limits for Composite Beams
Serviceability limits are increasingly becoming the critical design requirement for composite beams. A set of three illustrative design studies indicates that this is particularly true...
Highlights of the New ASCE Standards on Composite Deck Floor Slabs
This paper presents highlights of the newly approved and printed ASCE Standard on the design and construction of composite floor deck slabs utilizing cold-formed steel. In 1992 four documents...
Modern Design Concept for Composite Slabs with Ductile Behaviour
Numerous tests with different types of composite slabs have been carried out in the laboratory for constructional engineering of the University of Kaiserslautern, Germany in order to determine...
Chinese Standard for Concrete-Filled Tube Columns
In this paper an outline is given of the background, the design approach and some principal features of the Chinese Specification for the Design and Construction of Concrete-filled Steel...
European Good Practice in Composite Floor Construction
Previous European experience, research and design for composite slabs with profiled steel decking are discussed. Present efforts to harmonize composite slab design and good construction...
Composite Space Frame?Experimental/Analytical Study
This paper describes work carried out on a composite space frame system. The system, previously developed for roof construction, comprised a pyramidal arrangement of steel angles and circular...
Slim-Floor Beams: Design Criteria and Structural Behaviour
Partially concrete-encased steel beams are mostly employed due to their natural resistance to fire, but there may also be other reasons, e.g. to obtain smaller depths of construction....
Thermal Shielding in Continuous Span Composite Slabs
The increasing popularity in Europe of composite slabs with cold-formed steel decking has underscored the need to improve calculation rules for the fire resistance. Existing rules have...
