Hi. I’m Doug Patt and this is How to Architect. Conventional buildings typically stand alone. Their structural and mechanical systems are designed to serve and support one building. The Marina Bay Sands in Singapore is not that kind of complex. The towers at the sands are the most prominent feature as is the floating raft like structure at the top. The resort was designed by Safdie Architects and the structural engineering was done by Arup. The resort opened in 2010. The complex consists of the visually remarkable hotel towers with sky park platform above, a convention center, mall, museum, theaters, restaurants, pavilions, and a massive casino. The multi billion dollar complex of buildings is unique, but it’s the cantilevered sky park platform which is truly remarkable. All three towers are asymmetrically shaped and flair at the base. The entire composition is also curved in plan. For this reason the towers incorporate regularly spaced concrete sheer walls as the primary vertical and transverse structural system with the end concrete leg walls helping to resist longitudinal forces. The skypark is 1,115 feet long and 131 feet wide and cantilevers 213 feet on one side. The park includes a weighty infinity edge swimming pool with over 375,000 gallons of water that must remain completely level. The structural system for the park consists of post tensioned 33 feet deep steel box girders, large steel structs and trusses. The tricky part about having three separate buildings support one continuous building above is that buildings move independently. For this reason there are movement joints between each tower on the skypark allowing for thermal expansion and wind loads. Along with lateral loads the wind also induces vibrations in the structural system. Vibrations can also be man made. The building includes a 5 ton tuned mass damper to mitigate these forces…What’s really cool about these simulations is that they’re available to everyone. As you might imagine complex simulations like these are really expensive, especially for a small architectural firm like mine. But Simscale makes them available for free if you don’t mind your results being available to the general public. On their site you can actually view thousands of simulations from the community or adapt an existing simulation for your own use - and they run workshops regularly. If you’re an architect, engineer or designer Simscale can not only be used to predict wind loads, but also to ensure pedestrian comfort, validate ventilation and air conditioning, and review air quality and thermal comfort. All you have to do is sign up and upload your model. So, thanks again to Simscale for these really cool simulations that prove what the police knew 100 years ago - And also a big thanks free software that gives architects like me an incredibly powerful tool. I’m Doug Patt and we’ll see you next time.
