This thesis explored the concurrent validity of the Quick Test (QT) as a brief individual measure of intelligence by correlating it with the Wechsler Preschool and Primary Scale of Intelligence (WPPSI). The subjects were 72 urban preschool children (15 black, 57 white) from Muncie, Indiana. The subjects ranged in age from 4½ to 6½ years, and were chosen from diverse socioeconomic backgrounds. Subjects were randomly assigned to two groups, each comprised of 36 females and 36 males. Tests were administered by two graduate students in clinical psychology and rotated to control for the effects of testing order. The correlation coefficients between the QT and WPPSI Full, Verbal and Performance Scale IQs were r = .64, r = .67 and r = .52, respectively. All correlations were significant at the .001 level. The strong correlation (r = .67) between the WPPSI Verbal and QT IQ suggests that the QT may be a good brief measure of verbal intelligence. The mean IQs for the WPPSI Full (102), Verbal (99), and Performance (106) were all significantly different (p < .001) from the QT mean IQ of 92. This seems to suggest that the WPPSI and QT mean IQs should not be used interchangeably. Standard deviations for the WPPSI Verbal, Performance, Full Scale, and QT IQs were 14.63, 16.85, 15.92, and 20.51, respectively. The present concurrent validity is strong enough to support the use of the QT as a brief individual measure of verbal intelligence.

Recent fire tests on the Cardington full-scale test frame and observations from real fires have demonstrated the significance of connections in fire, when they can have beneficial effects on the survival time of the structure. The lack of experimental data on the behaviour of steel and composite connections in fire means that this is insufficiently addressed in current design codes and also limits the effective use of numerical models. However, recent experimental tests on small-scale specimens have shown that it is possible to derive accurately the moment-rotation relationships at elevated temperature and have established the principles by which this could be achieved. In order to extend the scope to include further parameters, five series of tests have been carried out in a portable connection furnace at the Building Research Establishment. The test series includes flush and flexible end-plate bare-steel connections, and flexible end-plate composite connections. The testing procedure and the resulting behaviour are described. The fire test temperature profiles across the connections are detailed and the connection failure mechanisms are discussed. From the test results, moment-rotation- temperature curves for different connection types are derived. The degradation of connection characteristics is compared with that of structural steel. The experimental behaviour is also compared with the results obtained from an existing finite element analysis developed to model connection response in fire conditions. The experimentally derived connection characteristics have been incorporated within a parametric study of a typical sub-frame, to study the effect of connection type, end-plate thickness, concrete strength, load ratio, and connection temperature. Analysis is extended to a three-dimensional sub-frame. The patterns of behaviour observed in the connection tests is compared with that of the connections in the large-scale fire tests on the composite building at BRE's Cardington laboratory. Based on knowledge about the behaviour of connections at elevated temperature, a component-based model is developed for the elevated temperature response for flexible end-plate connections, both as bare-steel and composite. This is based on the response of constitutive parts of connection. The model is easy to use, and capable of modelling the entire non-linear range of connection behaviour. The predicted response is compared with that recorded experimentally.
