NURBS based on the genetic algorithm is an important mathematical tool and consists of generalizations of Bezier curves and surfaces and B-splines. Generally, the accuracy of the design process of joints depends on the number of control points that are captured in the results of experimental research on real specimens. The values obtained from the specimens are the best tools to use in seismic analysis, though more expensive when compared to values simulated by SRSs. The SRS proposed in this paper can be applied to obtain surfaces that show site effect results on destructions of beam-column joint, taking into account different site conditions for a specific earthquake. The efficiency of this approach is demonstrated by the retrieval of simulated-versus-analytical results.}, type={Artykuły / Articles}, title={Symulacja reakcji sejsmicznej łączników belkowo-słupowych wykonanych z betonu zbrojonego z dostosowaniem powierzchni NURBS}, title={Simulation of seismic response of reinforced concrete beam-column joints with NURBS surface fitting}, URL={http://www.journals.pan.pl/Content/103355/PDF-MASTER/ace-2017-0029.pdf.pdf}, keywords={krzywa B-sklejana, NURBS, powierzchnia reakcji sejsmicznej (SRS), łącznik RC, model analityczny, algorytm genetyczny, właściwości tektoniczne, B-spline, NURBS, seismic response surface (SRS), RC joint, analytical model, genetic algorithm, tectonic characteristics}, }
