Large deformation structural performance of double skin composite construction using British Steel's 'Bi-Steel'
Double skin composite construction consists of two relatively thin steel plates with the space between filled with, usually, normal weight concrete. The transfer of shear between the steel and concrete is possible through the use of steel shear connectors that are welded to the steel plates. A …

Featural and holistic processing in facial composite construction: the role of cognitive style and processing sets
… a police investigation by constructing a facial composite of the perpetrator of the crime with the help of a police operator. A large body of research has investigated the utility of composite construction systems and the ways in which they are implemented with eyewitnesses. There has been less …

Running head featural composites and lineups: "What big teeth you have" - Red Riding Hood and the face recognition failure : the effects of isolated featural and configural composite construction and recognition accuracy
… Eyewitnesses are usually required to construct a composite of the perpetrator. Research has suggested that eyewitnesses who construct composites are more likely to misidentify the target in a later recognition task (Comish, 1987; Wells, Charman, & Olson, 2005; Yu & Geiselman, 1993). This hampering …

Floor Vibrations: Girder Effective Moment of Inertia and Cost Study
… and a cost efficiency analysis comparing composite and non-composite floor systems that meet vibrations design standards, were conducted. The first study was undertaken because over-prediction of girder effective moment of inertia was the suspected cause of several recent vibration …

Determinants of estimated face composite quality
… by police forces around the world, namely a face composite or facial likeness. The process of constructing a composite involves a number of cognitive elements, all of which contribute to the final composite quality. This thesis examines elements of the construction process and assessment of the …

Feasibility Study of Partially Restrained Connections
… steel joists, which are also quite common in construction, makes for shallower story heights and lower steel weights. This initial study analyzes partially restrained connections for both hot rolled shapes and steel joists using non-composite and composite construction. The designs are than …

Behaviour of long span composite beams with precast hollow-core slabs
… concrete slabs with Fabsec steel beams in composite construction has had little research conducted in this area. The main purpose of the research is to develop an understanding into the behaviour of this form of construction and to demonstrate the advantages of using Fabsec beams with …

Longitudinal Slab Splitting in Composite Girders
Longitudinal slab splitting in composite hot rolled girders and joist girders was investigated. Two different type of framing configurations were studied with two tests conducted per configuration. The framing configurations were designated as either flush-framed or haunched, which describes the …

Comparing featural and holistic composite systems with the aid of guided memory techniques
… compares the effectiveness of two computerised composite construction systems - a holistic, recognition-based system named ID and a featural system that is utilized internationally, namely FACES. The comparison aimed to test whether ID produces better quality composites to FACES, and whether …

Thermophysical Properties and Microstructural Changes of Composite Materials at Elevated Temperature
… developed and used to quantify the behavior of composite materials during heating to support development of heat and mass transfer pyrolysis models. Methods were developed to measure specific heat capacity, kinetic parameters, microstructure changes, porosity, and permeability. Specific heat and …

Composite Multi-Story Rigid Frames Under Gravity and Lateral Loads.
… the design of a 12-story rigid frame bent with composite girders when horizontal loads produce the maximum forces for which the girders must be designed. Using an asymmetrical rigid frame with column spacings of 22' and 28', it was found that a decrease in frame weight of slightly greater than …

The structural exploitation of fibrous-cement composites in reinforced concrete T-beams
… expounds the logic behind a new concept of composite construction which exploits fibre reinforced cement composites in the form of channels, placed in the tensile zone of reinforced concrete T-beams. The fibre reinforced cement composites, which act as 'surface reinforcement', incorporate …

Energy Absorption and Dynamic Behaviors of Architectured Interpenetrating Phase Composites
Novel interpenetrating phase composites show promise for structural aerospace components, but their structure-property relations are not well understood. In this work, we explore the effects of mesoscale geometry on mechanical behaviors of architectured interpenetrating phase composites. We first …

Numerical and Experimental Investigations on Static Behaviour of Composite Cold-Formed Steel and Timber Flooring System
… widespread. However, the potential benefits of composite action that arise due to the interaction of the top flange of cold-formed steel joist and the bottom surface of timber floorboard due to shear connection are not considered in the design of such a flooring system. As a result, it led to …
