This paper presents an introduction of the study for the design and technical development of a newly proposed guideway structure for the superconductive magnetically levitated train system...

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...

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....

Comparison of Simple Calculation Methods for the Fire Design of Composite Columns and Beams
There is a need for approximate calculation methods to do the fire design of composite structures. Several of such methods for composite beams and columns have been compared to find out...

Design of Shear Connectors in Composite Bridge Beams
A new approach is described for the design of stud shear connectors, in composite steel and concrete beams that are subjected to vehicular loads, which allows for the interaction between...

The Steel Deck Institute Method for Composite Slab Design
The Steel Deck Institute (SDI) of the USA has synthesized the composite slab research and testing that has been conducted in the U.S. during the past 25 years and has presented a design...
