Prior to the enforcement of seismic details, older-type fully encased steel-reinforced concrete composite (SCR) columns were utilized in many buildings and bridges constructed active regions worldwide. However, there is serious lack knowledge literature about behavior older buildings’ SRC with non-seismic details. Shear strength expressions, stiffness, backbone curves, nonlinear modeling parame...

In order to investigate the mechanical behavior of special-shaped reinforced concrete composite columns encased with GFRP core (EGCSSCs) subjected axial load, twenty-seven full-scale EGCSSCs were designed varying parameters: compressive strength (fcc), peripheral (fco), thickness tube (tgfrp), ratio longitudinal reinforcement (ρv), stirrup (ρs) and in cross-section (α). The three-dimensional fi...

The stability of the embankment’s slopes is a critical aspect geotechnical engineering and it essential to guarantee effectiveness factor safety prevent any potential failures in slope both during post-construction. current study consists two parts; first part behavior geogrid-encased granular columns their interaction with soil at shear surface generated by slippage soil, while second changing...

Distance maps of binary images contain. for each pixel, the distance between that pixel and the pixel of value 0 closest to it. They have important uses in computer vision, pattern recognition, morphology and robotics ( IO]. Many algorithms have been proposed for computing distance maps for a variety of distances such as the Li, L,, octagonal and Euclidean distances ]%I I-131. Recently, Kolounz...

Symmetric spiral inductors are used for differential circuit applications for their robustness and superior noise rejection properties. In this work, characteristics of quality factor and inductance of symmetric inductors having octagonal structures, and the methods to improve performance have been suggested using the Agilent Momentum simulator [1]. From the results, we get differential quality...

In this paper we prove that the transitive closure of a nondeterministic octagonal relation using integer counters can be expressed in Presburger arithmetic. The direct consequence of this fact is that the reachability problem is decidable for flat counter automata with octagonal transition relations. This result improves the previous results of Comon and Jurski [7] and Bozga, Iosif and Lakhnec...

Deformation of partially composite beams under distributed loading and free vibrations of partially composite beams under various boundary conditions are examined in this paper. The weak-form quadrature elementmethod, which is characterized by direct evaluation of the integrals involved in the variational description of a problem, is used. One quadrature element is normally sufficient for a par...

The theory of magnetic symmetry in quasicrystals, described in a companion paper [Acta Crystallographica AXX (2003) xxx-xxx], is used to enumerate all 3-dimensional octagonal spin point groups and spin space-group types, and calculate the resulting selection rules for neutron diffraction experiments. 1. Introduction We enumerate here all three-dimensional octagonal spin groups and calculate the...
