This paper investigates the optimum placement and properties of the Tuned Mass Dampers (TMDs) in tall buildings, which are employed to control the vibrations during earthquakes. An algorithm was developed to spend a limited mass either in a single TMD or in multiple TMDs and distribute them optimally over the height of the building. The Non-dominated Sorting Genetic Algorithm (NSGA - II) method was improved by adding multi-variant genetic operators and utilized to simultaneously study the optimum design parameters of the TMDs and the optimum placement. The results showed that under earthquake excitations with noticeable amplitude in higher modes, distributing TMDs over the height of the building is more effective in mitigating the vibrations compared to the use of a single TMD system. From the optimization, it was observed that the locations of the TMDs were related to the stories corresponding to the maximum modal displacements in the lower modes and the stories corresponding to the maximum modal displacements in the modes which were highly activated by the earthquake excitations. It was also noted that the frequency content of the earthquake has significant influence on the optimum location of the TMDs.}, subject = {Schwingungsd{\"a}mpfer}, language = {en} } @article{LahmerKoenkeBettzieche, author = {Lahmer, Tom and K{\"o}nke, Carsten and Bettzieche, Volker}, title = {Optimal positioning of sensors for the monitoring of water dams}, series = {WASSERWIRTSCHAFT}, journal = {WASSERWIRTSCHAFT}, pages = {16 -- 19}, abstract = {Optimal positioning of sensors for the monitoring of water dams}, subject = {Angewandte Mathematik}, language = {de} } @article{LahmerKoenkeBettzieche, author = {Lahmer, Tom and K{\"o}nke, Carsten and Bettzieche, Volker}, title = {Optimale Positionierung von Messeinrichtungen an Staumauern zur Bauwerks{\"u}berwachung}, series = {WASSERWIRTSCHAFT}, journal = {WASSERWIRTSCHAFT}, pages = {16 -- 16}, abstract = {Optimale Positionierung von Messeinrichtungen an Staumauern zur Bauwerks{\"u}berwachung}, subject = {Angewandte Mathematik}, language = {de} } @article{LahmerNguyenTuanKoenkeetal., author = {Lahmer, Tom and Nguyen-Tuan, Long and K{\"o}nke, Carsten and Bettzieche, Volker}, title = {Thermo-hydro-mechanische 3-D-Simulation von Staumauern-Modellierung und Validierung}, series = {WASSERWIRTSCHAFT}, journal = {WASSERWIRTSCHAFT}, pages = {27 -- 30}, abstract = {Thermo-hydro-mechanische 3-D-Simulation von Staumauern-Modellierung und Validierung}, subject = {Angewandte Mathematik}, language = {de} } @article{NguyenTuanKoenkeBettziecheetal., author = {Nguyen-Tuan, Long and K{\"o}nke, Carsten and Bettzieche, Volker and Lahmer, Tom}, title = {Numerical modeling and validation for 3D coupled-nonlinear thermo-hydro-mechanical problems in masonry dams}, series = {Computers \& Structures}, journal = {Computers \& Structures}, pages = {143 -- 154}, abstract = {Numerical modeling and validation for 3D coupled-nonlinear thermo-hydro-mechanical problems in masonry dams}, subject = {Angewandte Mathematik}, language = {en} } @article{BruhinStockDrueckeretal., author = {Bruhin, R. and Stock, U.A. and Dr{\"u}cker, J.-P. and Azhari, T. and Wippermann, J. and Albes, J.M. and Hintze, D. and Eckardt, Stefan and K{\"o}nke, Carsten and Wahlers, T.}, title = {Numerical simulation techniques to study the structural response of the human chest following median sternotomy}, series = {The Annals of Thoracic Surgery}, journal = {The Annals of Thoracic Surgery}, pages = {623 -- 630}, abstract = {Numerical simulation techniques to study the structural response of the human chest following median sternotomy}, subject = {Angewandte Mathematik}, language = {en} } @article{HaefnerEckardtLutheretal., author = {H{\"a}fner, Stefan and Eckardt, Stefan and Luther, Torsten and K{\"o}nke, Carsten}, title = {Mesoscale modeling of concrete: Geometry and numerics}, series = {Computers and Structures}, journal = {Computers and Structures}, pages = {450 -- 461}, abstract = {Mesoscale modeling of concrete: Geometry and numerics}, subject = {Angewandte Mathematik}, language = {en} } @article{UngerEckardtKoenke, author = {Unger, J{\"o}rg F. and Eckardt, Stefan and K{\"o}nke, Carsten}, title = {Modelling of cohesive crack growth in concrete structures with the extended finite element method}, series = {Computer Methods in Applied Mechanics and Engineering}, journal = {Computer Methods in Applied Mechanics and Engineering}, pages = {4087 -- 4100}, abstract = {Modelling of cohesive crack growth in concrete structures with the extended finite element method}, subject = {Angewandte Mathematik}, language = {en} } @article{UngerKoenke, author = {Unger, J{\"o}rg F. and K{\"o}nke, Carsten}, title = {Coupling of scales in a multiscale simulation using neural networks}, series = {Computers \& Structures}, journal = {Computers \& Structures}, abstract = {Coupling of scales in a multiscale simulation using neural networks}, subject = {Angewandte Mathematik}, language = {en} } @article{EckardtKoenke, author = {Eckardt, Stefan and K{\"o}nke, Carsten}, title = {Adaptive damage simulation of concrete using heterogeneous multiscale models}, series = {Journal of Algorithms \& Computational Technology}, journal = {Journal of Algorithms \& Computational Technology}, pages = {275 -- 297}, abstract = {Adaptive damage simulation of concrete using heterogeneous multiscale models}, subject = {Angewandte Mathematik}, language = {en} }
