This paper aims to assess the structural overstrength (R), seismic behaviour factor (Q), and effective inertia (keff), of which elastic stiffness (Keff) is a function, i.e., Keff reinforced concrete (RC) cantilever columns with solid circular sections in urban bridges. The R Q factors proposed design codes have been based mainly on an empirical basis. However, some studies suggest that, case RC...

During the service process, piers are often in harsh chloride ion erosion environments. The failure mode evolution of reinforced concrete (RC) may occur under action continuous corrosion. Accurately identifying types and characteristics corroded RC bridge is a prerequisite for lifetime seismic performance evaluations bridges. First, based on Fisher’s theory 174 pier columns as analysis samples,...

A procedure for using Guilford's structure of the intellect as the theoretical basis for a task analysis model is presented. It is reasoned that such a model would furnish a bridge between task analysis and test selection, and also a bridge between test selection and test validation. Such a mechanism might answer some of the Equal Employment Opportunity Commission (HOC) criticisms of psychologi...

Abstract In this study, the effects of selection and scaling procedures earthquake records on dispersion seismic response structures are examined. This is according to Standard No. 2800 code ASCE code. So that during two case studies, seven earthquakes have been selected scaled with spectral acceleration 2800. Besides, a reinforced concrete (RC) bridge 7-story RC building evaluated against eart...
