New procedure for dynamic structural reanalysis
(Latest Trends On Engineering Mechanics, Structures, Engineering Geology, 2010)
The methods of structural dynamic modification, especially those with their roots in finite element models, have often been described as reanalysis. The present paper deals with the problem of improving of dynamic ...
Buckling of Sandwich Plates using Layerwise Displacement Model / Izvijanje sendvič ploča primenom slojevitog modela ploče
(University of Montenegro, Faculty of Civil Engineering, 2010)
In this paper a layer wise displacement model is used to study buckling of sandwich plates [2]. Mathematical model assumes layer wise description of in plane displacements, constant transverse displacement and quadratic ...
Dinamička krutost pravougaonog temelja
(13. Kongres Društva građevinskih konstruktera Srbije - DGKS, 2010)
U dinamiþkoj analizi interakcije tla i objekta u frekventnom domenu, primenom metode podstruktura, uticaj tla se zamenjuje dinamiþkom matricom krutosti. Elementi te matrice su kompleksne, frekventno zavisne funkcije, koje ...
Developement Of Digital Model Of Terrain (Dmt) Using Autocad And Surfing Software Packages
(Belgrade: Faculty of Architecture in Belgrade; Serbian Society for Geometry and Graphics (SUGIG), 2010)
This paper considers a problem of developing a digital model of
topographic surface (terrain) which, as an empirical surface, requires
a specific approach in 3D modeling. The solution is found by using two
software ...
Dinamička analiza skladišta radioaktivnog otpada u Vinči
(Savez građevinskih inženjera Srbije, 2010)
U ovom radu je prikazana analiza uticaja mogućeg zemljotresa na jednostavan objekat, ali koji zbog svoje namene, skaldištenja radioaktivnog otpada, spada u "Objekate van kategorije". Dinamička analiza je obavljena primenom ...
Long-term behavior of composite concrete girders made continuous
(Precast Prestressed Concrete Institute, 2010)
Time-dependent effects play an important role in the design process of concrete structures. In order to predict time-dependant effects in concrete structures, engineers need reliable data for creep and shrinkage properties ...
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 ...
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 ...
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 ...
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 ...
