“When I model a floor plan, put on mesh, make a calculation of the load cases and control that the floor plan is correctly designed, Topi says. I then go on to the next floor and do the same thing until I have checked all the floors of the entire building. It provides a more efficient process…”, states Topi.
“I save time by working this way and avoid problems that might otherwise arise. If I model 16 floors and discover faults around the eighth floor, it is very difficult to find exactly what and where the error in the construction is. It takes time to analyse especially if it’s an advanced design”.
Finally, Topi conducts an overall global analysis of the entire building. The construction gets the right design and stability with FEM-Design as a useful tool.
Analysis of Connections between Elements
Recently Topi and his staff completed a project in Helsinki. A five-storey residential building built of precast concrete. The building has a basement of two floors and three floors above ground level. A rather complex design task with several challenges that the engineers solved with FEM-Design, so that the concrete elements got the right design for stability in the building.
“We analysed tensile stresses and how they effected the structure and how the loads were distributed. We also checked the forces in the horizontal concrete slabs and what they meant for the entire building. Special emphasis was placed on analysing how the forces were distributed in the connections between different types of elements and in the frame, for example hollow cores in relation to the foundation. That was all calculated in FEM-Design”.
Global Structural Analysis in Focus
According to Topi the biggest advantage of FEM-Design is that you get a holistic approach to designing the entire building.
“Even if we can make structural calculations by hand, we get a better picture with the results from the global analysis. We save so much time with FEM-Design, especially if the design is advanced and complex. But overall, the benefit with the global analysis is to ensure quality. Quality is necessary to succeed, this way, the engineers save time and resources and the building is designed correctly.”
