Projekt badawczo-rozwojowo + wdrożeniowy Narodowego Centrum Badań i Rozwoju oraz Narodowego Funduszu Ochrony Środowiska i Gospodarki Wodnej w ramach Programu GEKON pt.:
„Dynamiczne zarządzanie zdolnościami przesyłowymi sieci elektroenergetycznych przy wykorzystaniu innowacyjnych technik pomiarowych"
Na Wydziale Inżynierii Lądowej realizowane są 2 zadania:
1. Model dynamiczny konstrukcji wsporczych (słupów) z obciążeniami przekazywanymi poprzez przewody sieci
2. Model numeryczny słupów uwzględniający drgania przekazywane przez podłoże na konstrukcje (np. drgania komunikacyjne) oraz analiza wpływu tych drgań na zachowanie się przewodów

Special Issue "Symmetry in Building Model" |
|
|
|
Dear colleague,
Symmetry is an important characteristic of many historical and modern buildings all over the world. For buildings, symmetry is mostly reflectional and rotational. With the recent development of building models constructed with different techniques such as laser scanning and digital photogrammetry in the form of geo-referencing, structure from motion, and simultaneous localization and mapping (SLAM), a building’s symmetry can be further recorded and investigated. The symmetry can be analyzed in terms of structural mechanics, geometry, cultural aspects, aesthetics and so on. This Special Issue aims for contributions that report recent advances in realizing, modeling, and analyzing a building’s symmetries, including multidisciplinary development related to the building information model (BIM).

Abstract
In this paper, we present an enhanced growth method based on virtual displacements and strains fields for generating optimal design in terms of topology and geometry of plane trusses without the need of a generation of so-called ground structure. The method has been applied to the single load case problem with stress and size constraints in plastic design. In order to demonstrate the reliability and accuracy of the proposed method, three examples are carried out: Hemp cantilever, Chan cantilever and McConnel structure. |

Abstract
The paper deals with the Free Material Design (FMD) problem aimed at constructing the least compliant structures from an elastic material, the constitutive field of which plays the role of design variable in the form of a tensor valued measure λ supported in the design domain. (...) |
