Escapable Conclusions: Toomela (2003) and the Universality of Trait Structure.

A. Toomela (2003) concluded that personality structure may be shaped by a cultural mechanism, word meaning structure, and that the apparent universality of the Five-Factor Model (FFM) was the result of inadequate sampling of concrete thinkers. A reanalysis using targeted rotation showed that the intended structure was generally replicated; small deviations in the most concrete thinkers were probably due to measurement error. The reanalysis authors found no evidence of structural differences in a second sample of adults classified as concrete or abstract thinkers. The FFM structure has been replicated in many samples containing individuals with cognitive or educational limitations; observer ratings may be preferred if these limitations are severe. To date, there is no compelling evidence that culture affects personality structure. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Experimental Study of Seismic Behaviors of As-Built and Carbon Fiber Reinforced Plastics Repaired Reinforced Concrete Bridge Columns

In order to reliably obtain seismic responses of as-built and repaired reinforced concrete bridge columns under near-fault ground motions, pseudodynamic testing of two bridge columns with a reduced scale of 2/5 was performed. Pseudodynamic test results reveal that a ductile member may have no chance to entirely develop its ductile behavior to dissipate seismic energy, because it may suddenly be destroyed by a significant pulse-like wave. The seismic performance of the two damaged bridge columns can be recovered after repair with carbon fiber reinforced plastics composite sheets. It is also experimentally confirmed that the flexural failure moment obtained from the pseudodynamic test is in good agreement with the plastic moment predicted by the ACI 318 code. As pseudodynamic test results are believed to be more accurate than numerical solutions, they can be considered as reference solutions in developing a finite-element model. An identical specimen was tested under cyclic loading to estimate basic properties of these columns, such as shear strength, flexural strength, and ductility, so that the seismic responses obtained from pseudodynamic tests can be thoroughly discussed. Furthermore, its hysteretic response may also be used to match a mathematical model to simulate the very complicated load-displacement relation for analysis.     

Effects of superstructure flexibility on strength of reinforced concrete bridge decks

This research studies the impact of the relative rigidity between the concrete bridge deck and the remaining structural components of the bridge superstructure on the behavior of the concrete deck. The study uses non-linear 3-D FEM models, which are developed using ANSYS 5.7 software package. Experimental data from one-span non-composite bridge superstructure are used to validate and calibrate the proposed FEM models. A series of parametric studies is conducted with respect to three parameters: (a) composite action, (b) slenderness ratio, and (c) presence of diaphragms. The analysis results are discussed in detail and conclusions on the behavior of the bridge deck are presented.
