Using Rotations to Obtain Compatibility Equations for Statically Indeterminate Trusses

This paper presents a new way of determining the compatibility conditions for statically indeterminate trusses. It is based on equations relating the angular displacements (rotations) of truss elements to the corresponding extensions obtained by requiring the displacements of the truss structure to be compatible, i.e., single valued. This new angular displacement method is likely to be most adv...

the role of sport shoes packaging as a media in persuading different groups of athletes to buy sport shoes

the aim of this study was to investigate the role of sport shoes packaging in persuading different groups of athletes to buy sport shoes. the methodology was descriptive-survey. the statistical population consisted of 1800 athletes of sport clubs of poldokhtar city. 329 subjects were selected as the sample by morgan table using clustering random sampling method in those clubs. a researcher-made...

Mathematica Applied to Evaluation of Influence Lines and Envelopes of Statically Indeterminate Beams

The paper presents an analytical method of finding functions of influence lines of statically indeterminate beams. There are presented solutions of a fourth order equation with a right hand side with second and third derivative of Dirac delta. There is shown that their solution are influence lines of moments and transverse forces. Moreover, thanks to Mathematica, analytical form of envelopes fu...

Identification of Axial Forces on Statically Indeterminate Pin-Jointed Trusses by a Nondestructive Mechanical Test

This work concerns the stress-state identification, produced by loads or dislocations, of statically indeterminate structures. In particular, this paper deals with the case of pin-jointed trusses, since they are a combination of simplicity of the structural model with very interesting technical applications. We present an approach that follows the main guidelines of the flexibility method to re...
