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...
A Simple Finnish Method for the Structural Fire Design of Composite Structures
The structural fire design of composite structures in Finland has previously been based on furnace tests, which are expensive and take too much time to arrange. With the increasing prominence...
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...
Connection of Grouted Tubular Insert Piles to Soil
Force transfer between offshore production jackets and tubular piles is effected by weld bead shear connectors, acting within the grout filled annulus between the piles and pile sleeves...
The Connecting Method of Steel and Concrete Using Long Deformed Bar Studs
A new welding technique for long horizontal studs of 19 mm and 22 mm diameters was established. The transmission of shearing and bending forces was evaluated using large model tests. Actual...
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...
Summary Report Design Session
The Tuesday presentations were devoted to design. Eight papers were presented in the morning general session and 17 presentations were made in 4 concurrent evening workshops. Diversity...
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...
Design of Composite Slabs for Vertical Shear
Three major modes of failure should be considered in the design of the positive moment regions of composite slabs incorporating profiled steel sheeting, viz.: flexure, longitudinal slip...
Effects of Creep in Cable-Stayed Composite Bridges
The paper summarizes the various ways in which creep in the concrete slab may affect the stresses in a cable-stayed composite bridge. It explains one effect in particular which is not...
Interaction of Steel Structure and Composite Supercolumns in Spine Structures
Modern architecture has departed from uniform rectangular cigarette boxes for high-rise buildings. A structural system which goes uninterrupted through the common denominator of the varying...
Double Skin Composite Construction for Submerged Tube Tunnels
A new form of sandwich construction consisting of two relatively thin steel plates, with a concrete infill has been developed for use in the construction of submerged tube tunnels. The...
Cyclic Lateral Load Analysis of Composite Frames
A method of analysis for composite building frames subjected to repeated and reversed lateral loads has been developed as part of an overall investigation of seismic response of composite...
Seismic Performance and Composite Action of Older Structures
A study into the seismic performance of older steel structures is described. A review is made of the types of steel building construction completed during the period of interest, and the...
Semi-Rigid Joint Action in Composite Frames: Numerical Analysis and Design Criteria
The paper focusses on the analysis of semi-rigid composite frames, reporting mainly on the results of a research study which combines the experimental and theoretical approaches. Attention...
Ductility Effects of End Details in Composite Beams
A limit states criterion is described for quantifying the rotation capacity of members in indeterminate structures as a means of classifying ductility of structures during plastic behaviour...
Seismic Response of Composite Coupled Walls
In many structures, height restrictions may require coupling of reinforced concrete walls by structural steel beams rather than conventional reinforced concrete beams. Through an experimental...
Investigation of Corners and Joints Applied to a Steel-Concrete Composite Caisson
We have developed a caisson composed of steel-concrete composite slabs and steel structures, which we call a `Hybrid Caisson.' We studied the structural principles and usability of the...
Development of Composite Slab with Truss-Typed Shear Connectors
This paper describes the results of the test on a steel-concrete composite slab with truss-typed shear connectors. This composite slab was recently developed. A series of tests were conducted...
