The dimensions of a bearing structure tend to be designed as slender possible ensure aesthetics and save material, which makes the more susceptible damage caused by shear forces. When is subjected an earthquake, failure even primary mode failure. Research on stress has always been great interest scientists. This paper presents efficient method for assessment prismatic beams with arbitrary cross...

This paper presents the use of a finite element method (FEM) to analyze shear lag effect due flexure beams with an arbitrary cross-section and homogeneous elastic material. Beams are constrained by most common types supports, such as fixed, pinned, roller. The transverse, concentrated, or distributed loads act on through center cross-section. presented FEM transforms 3D analysis phenomenon into...

A method has been developed which automatically generates SMARTS patterns for four-atomic torsional fragments, searches experimental structures in the Cambridge Crystallographic Database, and obtains rules for preferred torsion angles in drug-size molecules. These rules can be used for exhaustive conformational analysis using the popular conformer generator OMEGA. This approach results in an ov...

Radial velocity (RV) monitoring of solar-type visual binaries has been conducted at the CTIO/SMARTS 1.5-m telescope to study short-period systems. Data reduction is described, mean and individual RVs of 163 observed objects are given. New spectroscopic binaries are discovered or suspected in 17 objects, for some of them orbital periods could be determined. Subsystems are efficiently detected ev...
