Modalna analiza ramovskih konstrukcija primenom metode spektralnih elemenata
(Zbornik radova 13. kongresa DGKS, Zlatibor-Čigota, 2010)
Dinamička analiza ramovskih konstrukcija u frekventnom domenu ima niz
prednosti. Za gredne elemente mogu se primeniti spektralni elementi čija je
dinamička matrica krutosti frekventno zavisna, dobijena rešavanjem ...
The Complement of the Hugelschaffer’s Construction of the Egg Curve
(Belgrade: Faculty of Architecture in Belgrade; Serbian Society for Geometry and Graphics (SUGIG), 2010)
Hügelschäffer’s construction, based on the distortion of the
ellipse construction, provides an egg-shaped curve. This curve is a
mixed cubic curve, the cubic hyperbolic parabola of type A. Curve is a
three-branched and ...
Constructing the Egg Curves Using the Golden Ratio of Pentagon
(Belgrade: Faculty of Architecture in Belgrade; Serbian Society for Geometry and Graphics (SUGIG), 2010)
In the paper it is considered a construction of an egg curve
obtained by continual joining of the circular arcs with three different
centers. These three centers form sharp or flat triangles of the
pentagon (sharp and ...
Investigation of Vibration Caused by Traffic and Railway Load
(Missouri University of Science and Technology, 2010)
Two examples related to the investigation of vibrations in civil engineering structures are presented. In the first example, it is shown how it is possible to decrease vibration in underground structures. These vibrations ...
Conic Section of a Type of Egg Curve Based Conoid
(Belgrade: Faculty of Architecture in Belgrade; Serbian Society for Geometry and Graphics (SUGIG), 2010)
A cubic egg curve obtained by Hügelschäffer’s construction,
can be spatially interpreted as a plane section of a type of a conoid
set through a specially chosen 4-th order intersecting curve of two
quadrics: right ...
Forming the Cupolae With Concave Polyhedral Surfaces by Corrugating a Fourfold Strip of Equilateral Triangles
(Belgrade: Faculty of Architecture in Belgrade; Serbian Society for Geometry and Graphics (SUGIG), 2010)
The cupolae with concave polyhedral surfaces consist of: two regular
polygons, n-gone and 2n-gone in parallel planes, interconnected by an
envelope constituted of series of equilateral triangles. The paper
describes ...
