Abstract
Description
Gegenstand der Erfindung ist der Schutz von Hochhäusern gegen dynamische Lasten hervorgerufen durch Erdbeben und Wind. Im Weiteren soll damit auch ein Schutz des mobilen Inventars in Gebäuden erreicht werden.object The invention is the protection of high-rise buildings against dynamic loads caused by earthquakes and wind. In addition, so should also a protection of mobile inventory in buildings can be achieved.
Das
gebräuchlichste
Mittel zur Minderung von Erdbeben- und Windlasten ist der TMD, der
Tuned Mass Damper. Hierbei handelt es sich um mechanische, auf die
kritische Belastungsfrequenzen abgestimmte Resonatoren, bestehend
aus Masse, Feder und Dämpfer.
Wie aus den Patentschriften
Aufgabe der Erfindung ist, zum Schutz von Hochhäusern gegen Erdbeben und Sturm das vorhandene, bewegliche Mobiliar zur dynamischen Dämpfung einzusetzen. Dazu werden die Mobiliarmassen über Federelemente mit der Gebäudestruktur zu Chattle-Tuned Mass Damper (C-TMD) zusammengekoppelt, um damit einen – in der englischen Bezeichnung – Tuned Mass Damper (TMD) zu realisieren.task The invention is to protect high-rise buildings against earthquakes and storms to use the existing, movable furniture for dynamic damping. In addition the Mobiliarmassen over Spring elements with the building structure Coupled to Chattle-Tuned Mass Damper (C-TMD) to use with it one - in the English name - Tuned To realize Mass Damper (TMD).
Nach einem weiteren Merkmal wird zur Verringerung der Einschwingzeit und zur Schwingungsbegrenzung der Mobiliarmassen eine über die natürliche hinausgehende, zusätzliche Dämpfung eingeführt.To Another feature is to reduce the settling time and to the vibration limitation of the Mobiliarmassen one over the natural going beyond, additional damping introduced.
Nach einem weiteren Merkmal sind die Mobiliarmassen im Ruhezustand örtlich arretiert. Bei Überschreitung einer Schwingungsschwelle löst sich die Arretierung selbsttätig oder wird gesteuert deaktiviert um dann als dynamische Stützmasse wirken zu können.To In another feature, the Mobiliarmassen are locally locked in the idle state. When exceeded a vibration threshold triggers the locking automatically or is controlled deactivated then as a dynamic support mass to be able to act.
Nach einem weiteren Merkmal wird der maximale Schwingungsausschlag der Mobiliarmasse durch Anschläge begrenzt. Mit Federelementen deren Federkonstante progressiv ansteigt wird ebenfalls eine Schwingungsbegrenzung erreicht.To Another feature is the maximum swing of the Mobiliassasse by stops limited. With spring elements whose spring constant increases progressively is also achieved a vibration limitation.
Nach einem weiteren Merkmal werden im Erdbebenfall die losen Massen innerhalb eines Mobiliars fixiert, um diese mit als Stützmasse zu nutzen und als Schutz gegen deren Beschädigung.To Another feature in the earthquake case, the loose masses within fixed a Mobiliars, in order to use these as support mass and as protection against their damage.
Nach einem weiteren Merkmal wird eine Regelung der Federelemente und/oder der Dämpfungsmittel nach den Vorschriften der Antischwingungstechnik – die englische Bezeichnung ist AVC = Active Vibration Control – vorgesehen.To Another feature is a regulation of the spring elements and / or the damping means according to the regulations of anti-vibration technology - the English Name is AVC = Active Vibration Control - provided.
Der Erfindungsgegenstand ist anhand verschiedener Ausführungsbeispiele weiter spezifiziert:Of the Subject of the invention is based on various embodiments further specified:
Zur
Beschreibung wird vorab folgende Zeichengebung vereinbart: X dient
als Zeichen für
die betreffenden Figur. X0 bezeichnet den Befestigungspunkt, der
eine starre Verbindung zur tragenden Struktur eines Hochhauses hat.
Dies kann wahlweise Wand, Boden oder Decke in einem Raum sein oder die
Träger
selbst. Mittels eines Federelementes X2 wird eine Mobiliarmasse
X1 an den Befestigungspunkt X0 angekoppelt. Als Mobiliarmasse X1
kommen letztlich alle mobilen Einrichtungsgegenstände mit
ausreichender Eigenmasse infrage. Falls dies funktionell tolerabel
ist können
auch Einheiten, die ursprünglich
eine starre Verbindung zur Gebäudestruktur
hatten, elastisch angekoppelt und ebenfalls als Mobiliarmasse X1
genutzt werden. Die Federelemente X2 können durch eine Pendelaufhängung, durch
schiefe Ebene und durch elastische Biege-, Dreh- oder Zugfeder realisiert
werden. Ausdrücklich zugelassen
sind Federelementen X2 mit einer nichtlinearen, progressiven Federkonstanten.
Eine Halterung X3 dient dazu, die Mobiliarmasse X1 im Ruhe- und
Gebrauchszustand örtlich
zu fixieren und erst im Bebenfall nach Überschreiten eines einstellbaren Grenzwertes
freizugeben. Eine sich selbsttätig
lösende
Halterung X3 kann in an sich bekannter Weise durch eine Vertiefung
(
Die bauseitig am Befestigungspunkt X0 wirkenden Masse M, die Masse m der Mobiliarmasse X1, die Federkonstanten c des Federelementes X2 und die Dämpfung k des Dämpfungsmittels X5 bilden einen Resonator, mit der Eigen(kreis)frequenz ω0 = sqr(c/m) (für m << M) und dem Verlustfaktor η0 = k/ω0m. Bei seiner Eigenfrequenz ω0 hat ein solcher Resonator die Resistanz R0 = ω0m/η0 mit der Halbwertsbreite Δω = ω0η0. Die wirksame Resistanz R ist an sich unabhängig vom Verlustfaktor η0, wegen der rascheren Einschwingzeit und der kleineren Resonanzausschläge ist es trotzdem vorteilhaft die natürliche Dämpfung durch ein zusätzliches Dämpfungsmittel X5 zu erhöhen. Bei einer mittleren Bebenschnelle v am Befestigungspunkt X0 liefert der Resonator eine Resistivkraft F = vR und absorbiert eine Schwingungsleistung N = v2R.The on-site at the attachment point X0 acting mass M, the mass m of Mobiliarmasse X1, the spring constant c of the spring element X2 and the damping k of the damping means X5 form a resonator, with the eigen (circle) frequency ω 0 = sqr (c / m) ( for m << M) and the loss factor η 0 = k / ω 0 m. At its natural frequency ω 0 , such a resonator has the resistance R 0 = ω 0 m / η 0 with the half-width Δω = ω 0 η 0 . The effective resistance R is independent of the loss factor η 0 , because of the faster settling time and the smaller resonance excursions, it is still advantageous to increase the natural damping by an additional damping means X5. At a mean quake velocity v at the attachment point X0, the resonator delivers a resistive force F = vR and absorbs a vibration power N = v 2 R.
