Terraced Tower (Rotterdam, Netherlands)
Terraced Tower is a 110 m high building (100 m above the ground) located in Rotterdam. Next to 3 floors in the basement, Terraced Tower has 32 floors above the ground used for apartments. The length of the building is decreasing along the height from 100 m to 35 m while the width is increasing from 20 m to 30 m.
First, the loads on the walls in the basements are so huge that high concrete grade C90/105 is necessary. Second, the tower is inclined with an 8 m cantilever producing important second order effects. Third, no available space around the construction pit and the need to work under existing pipes lead to difficult construction stages for the basement.
SCIA Engineer was used for the entire design of the project. The automatic design of 2D concrete member was useful to quickly design the walls described as the first issue. For the second issue, the second order coefficients were determined using SCIA Engineer. For the last problem, the “construction stages” module was used to design each stage. To conclude, SCIA Engineer allowed us to quickly design the reinforcement of the elements which in turn gave us the possibility to focus on the coordination and the management of the project.
"The use of high concrete grade and the big cantilever makes it even more difficult, but thanks to the intensive use of SCIA Engineer, including construction stages, the realisation of this project was possible."
