In this episode, we talk with Shayne Love, technical director at Motioneering Inc., which is part of the RWDI Group of Companies, about the structural dynamics in modern construction, focusing on game-changing technologies like tuned mass dampers and their application in structures from bridges to skyscrapers. ***The video version of this episode can be viewed here.*** Engineering Quotes: Here Are Some of the Questions We Ask Shayne: Could you explain what Motioneering is and specify its area of expertise? How does Motioneering play a role in exploring technologies such as dampers to control and enhance structural motion? Does RWDI utilize a physical wind tunnel facility for testing, or is the testing more computer-simulated, resembling Finite Element Analysis (FEA)? What scale do you usually use when constructing replicas? How does structural motion pose challenges and impact the integrity of buildings and bridges? Do you solve the elevator cable issue by having separate elevators for different sections of the building? What technologies or solutions do you typically employ to address serviceability and motion issues in structures? Can you explain how tuned mass dampers and sloshing dampers work to minimize movement in structures? What materials are used to make tuned mass dampers (TMDs)? Will the project owner hire your firm separately for wind analysis and designing the damping system, in addition to the structural engineer? What does the term "tuned" imply, does it involve automation with computers, and where does the tuning aspect come into play? How do motion control and dealing with structural dynamics differ for bridges compared to high rises? How do the floor damper systems look when installed, what materials are used, and how are they attached to the floor? How do engineers showcase the real-world effectiveness of dampeners in practical scenarios? Is the maintenance required for tuned mass dampers substantial, or is it generally minimal? Can tuned mass dampers be added toward the end of construction, and how does this fit into the building's occupancy timeline? What advice do you have for aspiring engineers looking to pursue a career in structural dynamics and motion control? Here Are Some of the Key Points Discussed About Tuned Mass Dampers:  RWDI and Motioneering are sister companies focused on wind engineering. RWDI excels in wind tunnel testing for 16 of the world's 20 tallest buildings, ensuring structural safety. Motioneering, a former RWDI department, specializes in controlling and reducing structural motion. Together, they bring innovation and safety to the dynamic field of structural engineering. When it comes to designing tall buildings and long-span bridges, just relying on codes isn't enough. You need extensive wind tunnel testing and dynamic simulations to figure out the loads accurately, avoiding unnecessary costs and structural problems. The historic failure of the Tacoma Narrows Bridge serves as a lesson on the importance of addressing dynamic responses. Nowadays, we focus on cable-stayed, flexible bridges and thorough testing to ensure modern structures don't face the same issues. At RWDI, they primarily use physical wind tunnel testing rather than just numerical modeling. In their office, you'll find aeroelastic bridge models that physically demonstrate how structures respond to wind. For tall buildings, replicas are built and placed in a mini urban environment, like a small downtown New York City, to simulate real-world conditions. This testing allows them to measure forces on structures and predict the loads and accelerations occupants might experience. Replica scales at RWDI vary based on the structure being studied; ...
