T1  - Passive Control of Tall Buildings Using Distributed Multiple Tuned Mass Dampers
N2  - The vibration control of the tall building during earthquake excitations is a challenging task due to their complex seismic behavior. 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.

T1  - Energie-basierte Auslegung von Tragsystemen für Hochhäuser in Abhängigkeit von der Größenordnung
N2  - Angelehnt an Entwicklungen des aktuellen Hochhausbaus, die Gebäudehöhen von über 600 m vorsehen, behandelt die vorliegende Arbeit Möglichkeiten der Konzeption von Aussteifungssystemen. Ein ausgewähltes Tragwerk aus Stahlbetonschubwänden und einer Höhe von 800 m wird mit der 3D-Analyse-Software ETABS (Version 9.0.9) bemessen. Dieses Tragwerk wird mit extremen Einwirkungen infolge Wind und Erdbeben belastet. Da ein solch hohes Gebäude außerhalb der Anwendungsgrenzen internationaler Normen liegt, wird ein eigener Ansatz für den Lastfall Wind zur Analyse des Schwingungsverhaltens gewählt. Aufbauend auf den Ergebnissen der Analyse werden Möglichkeiten der Reduktion bzw. Dämpfung von kritischen Gebäudeschwingungen diskutiert. Die konkrete Dämpfungsvariante „Passiver Schwingungsdämpfer“ (Tuned Mass Damper) wird, unter Verwendung von Optimierungskriterien, in ETBAS modelliert und in die Berechnungen eingebunden. Dieses Tragwerk wird zwei kleineren Tragwerken (H = 200 m bzw. 400 m) gegenübergestellt und mittels dem MIPS-Konzept (Material-Input pro Serviceeinheit) analysiert. Ziel ist es dabei, qualitative Aussagen zur Nachhaltigkeit und ökologischer Effizienz besonders hoher Gebäude zu treffen.

T1  - DEVICE FOR SEISMIC PROTECTION OF BUILDINGS
N2  - Seismic insulation is one of the most progressive types of seismic protection. Seismic insulation is understood as applying special devices for reducing of inertial seismic loads acting on a building. The constructions, shown in article, significantly more effectively solve problems of seismic protection, comparing to the existing seismic insulation systems (SIS). The Special Mechanical Engineering Design Office has developed, manufactured and tested a shock-absorber unit (SAU) of large load capacity. The SAU represents a block of number of pneumatic shock-absorbers (PSA), concentrically mounted round the guiding cylinder. The protected object rests upon the upper movable part of the guiding cylinder of the SAU. In its turn, the lower part of the SAU is rested on the foundation plate, mounted on the ground. A set of the SAU is a constructive realization of the SIS. Efficiency of such SIS has been proved as theoretically, so experimentally An effective SIS can also be created on the base of the elasto-plastic shock-absorbers developed by the KBSM. New designing and constructional solutions are based on the use of the original SIS elements, performed on the base of long time existing (in the other field of technical equipment)units, safety and durability of which have been proved by long term service (more than 20 years).
