Experience in motion control The MAURER Group is a leading specialist in mechanical engineering and steel construction and has been family-owned since it was formed back in1876. The MAURER Group is currently one of the global technological leaders in steel and plant constructions in various specialist fields. We offer products and solutions which are particularly notable for their quality, durability and reliability. MAURER Our fields of expertise are customised structural protection systems Expansion joints structural bearings Tuned Mass Dampers Anti-Seismic Devices An important part of...

Megacities of tomorrow will grow in population, infrastructure and height Due to the urbanisation of the world’s population, which in some cases is occurring at rapid speed, politicians, city planners and transport system developers are facing new challenges. For many academics, the solution for the city of tomorrow lies in its compactness. “Buildings better connected, more compact cities based on mass public transport can save over $3 trillion in investment costs over the next 15 years. These measures will improve economic performance and reduce emissions, raising the quality of life.” New...

MAURER Tuned Massto efficiently solve vib The challenge Civil engineering structures may be prone to large amplitude vibrations due to wind and earthquake loading mechanisms because of their slenderness and low inherent damping ratio of approx. 1%. Without additional damping measures the following problems may arise: Wind loading mechanisms may evoke resonance and therefore large amplitude oscillations in high-rise buildings, which dramatically reduce the comfort (seasickness) and therefore limit the use of the building. Free vibrations of tall buildings after earthquake excitation may...

Dampers – designed ration problems The MAURER solution MAURER offers different types of tuned mass dampers (TMD) with up to 1,000 tonnes of tuned mass to optimally solve the vibration problem: >> Passive tuned mass dampers: tandardTMDs: TMDs constructed with s springs for the mitigation of vertical and horizontal oscillations of bridges, stadiums and floors, and TMDs designed in pendulum form for the mitigation of horizontal vibrations of slender structures. oldedTMDs: TMDs constructed by f two folded pendulums in order to significantly reduce the required vertical space in high-rise...

■ The key features of Tuned Mass Dampe Benefits of MAURER TMDs • The different mass damper types guarantee the best solution to the vibration problem. • Model-based optimal design of all mass damper types by MAURER as a service. • Vibration measurement on the structure by MAURER. • Quality control by measurement of TMD properties in the workshop and installed in the structure. >> Specific benefits of MAURER TMDs standardTMDs: cost efficient • MAURER TMDs are robust, maintenance-free and long-lasting (>20 years) due to their optimal design, precise manufacturing process and quality controls....

Resilient structures in a fast-moving world >> SOCAR Tower in Baku | Azerbaijan >> Danube City Tower in Vienna | Austria Task: Mitigation of fundamental bending modes in both main directions with different eigenfrequencies Task: Controlled mitigation of first bending mode within the frequency range of 0.17 Hz to 0.21 Hz Scope of project: he total height of the folded pendulum T including the steel frame construction, cable clamping devices and lead rubber bearings could be reduced from approx. 11 m of the conventional pendulum TMD to approx. 7 m of the foldedTMD. Scope of project: The...

280 TONNES OF STEEL 7 FULLY LOADED SEMi-TRAiLERS >> Alphabetic Tower in Batumi | Georgia Task: Mitigation of wind-induced vibrations in both main directions >> Marina Bay Sand Hotel | Singapore Task: Reducing the vertical vibrations of the cantilevered part due to wind and human-induced excitation Scope of project: • The standardTMD in pendulum form is optimally tuned to the eigenfrequency of 0.498 Hz in both main directions of the Alphabetic Tower in Batumi. • The damper mass of 62.85 tonnes of the standardTMD corresponds to the mass ratio of 3.5 %. • The joints and lengths of the...

iN TIME iN BUDGET >> Olympic Flame Monument in Sochi | Russia Task: To dampen the vibration of a 45 m tall torch in the Sochi Olympic Park at the windy coast of the Black Sea >> AlpSpix in Garmisch-Partenkirchen | Germany Task: The vibration of the viewing platform needed to be reduced to a sensitive comfort level for visitors. Scope of project: • Each of the three dampers weighs one tonne, 750 kg of which damper mass. • The natural frequencies of the standardTMDs can be optimally adjusted to the broad frequency range of 0.46 Hz to 1.55 Hz by the unique design of these standardTMDs that...
