Tuned Mass Dampers

A&H Custom Machine is a world leader in the design, fabrication, and installation of tuned mass dampers.

Our reputation for excellence in this area has led us to a variety of notable projects around the world including famous landmarks such as Taipei 101, Spire of Dublin, Las Vegas Control Tower, and the Royal Alexandra Interprovincial Bridge.

What is a tuned mass damper (TMD)?

The technical definition of a tuned mass damper (TMD) is a device mounted in large structures, such as tall buildings and long bridges, to reduce the amplitude of vibrations caused by environmental forces or otherwise. Tuned mass dampers are typically constructed of large steel bodies and mounted to move in an opposing fashion to the oscillations of the structure.

This is important to structures such as tall buildings and bridges because it helps allow them to remain stable under harsh conditions such as strong winds and even earthquakes. Over the years TMDs in various structures have been responsible for keeping structures safe and reducing the amount of damage that harsh weather conditions can wreak on those structures.

Further vibrations can also come from man-made causes – such as cars or trucks passing over a bridge. By reducing the number of vibrations through TMDs, we are also helping to reduce wear and tear on those structures which can translate into the need for less frequent or less costly maintenance or repairs.

Why A&H Custom?

The A&H team implements all aspects of creating TMDs for various projects. From our highly skilled engineers to our manufacturers and installers, we all work together to achieve a common vision. Each project whether it be a bridge, a high rise apartment building or something else is unique. And while there are some basic principles that will be common in the design of all TMDs, there are also going to be unique considerations for each project as well. Since our team handles the entire process from design to installation, it is much easier for us to work together and to troubleshoot any problems.

Our design engineers work with architects to design TMDs that fit seamlessly into building plans. Our manufacturers and installers then create and install them, working alongside builders and project managers.

Our Commitment to Our Customers

At A&H Custom Machine, we attract customers from all over the world. We’ve worked on many contracts for TMDs for massive projects including skyscrapers, airports, and bridges. We are honoured by the trust that our clients put in us and take our responsibility to preserve the safety and structural integrity of their projects very seriously.  

We have been in business since 1986 and have always maintained the highest level of professionalism and expertise.  

Our expert team has built and installed more tuned mass dampers for buildings than any other firm in the world. We are extremely proud of all the work we have completed to date and look forward to many more exciting projects in the future.
