AUTOMATED BIM ENTITY RECONSTRUCTION FROM UNSTRUCTURED 3D POINTCLOUDS
Autor: Voříšek, Jan; Patzák, Bořek; Dvořáková, Edita; Rypl, Daniel
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)Laser scanning is used widely in architecture and construction to document existing buildings by providing accurate data for creating a 3D model. The output is a set of data points in space, so-called point cloud. While ... -
ISOGEOMETRIC BEAM ELEMENT EXTENDED FOR GRIDSHELL ANALYSIS
Autor: Dvořáková, Edita; Patzák, Bořek
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)The design of gridshell structures is a complicated process, as the resulting shape of structure depends on initial undeformed grid geometry as well as on the history of boundary conditions used to form the final structure. ... -
ON COMPARISON OF 3D ISOGEOMETRIC TIMOSHENKO AND BERNOULLI BEAM FORMULATIONS
Autor: Dvořáková, Edita; Patzák, Bořek
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)Application of isogeometric analysis (IGA) for curved beams is very convenient for its ability of exact representation of curved geometries. Several beam formulation has been presented since the introduction of IGA. In ... -
ON DEVELOPMENT OF THE INTERACTIVE DESIGN TOOL BASED ON ISOGEOMETRIC ANALYSIS
Autor: Dvořáková, Edita; Patzák, Bořek
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)Isogeometric analysis is a new concept of Finite element method which has been proposed to bridge the gap between the CAD systems and the FEM solvers. In Isogeometric analysis, the same basis functions, typically splines ... -
ON EVALUATION OF THE THREE-DIMENSIONAL ISOGEOMETRIC BEAM ELEMENT
Autor: Dvořáková, Edita; Patzák, Bořek
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)The exact description of the arbitrarily curved geometries, including conic sections, is an undeniable advantage of isogeometric analysis (IGA) over standard finite element method (FEM). With B-spline/NURBS approximation ...
