The solution for your building

The system for timber frames

Flexframe is a system that has been developed at ETH Zurich. The market implementation of this system is one of the key aspects of Swiss Timber Solutions. 

The system

The system is explained fairly easy; columns made of hardwood are connected with beams made of glulam with a tendon. The tendon force presses the beams against the columns, thus stabilizing the frame. The frame can carry gravity loads as well as horizontal loads due to wind and earthquake.

The picture gallery on the right shows the construction process of the House of Natural Resources. 

Flexframe stands for densification

Flexframe can be used to top up existing structures, i.e. to add additional stories to a building. Due to the lateral stiffness of of the frame, there is no need for additional walls or a staircase made of concrete. In the ideal case the frame can be placed on the existing building without having to reinforce the existing structure. Such a project was developed by High Tech Timber. More living space in the shortest possible time thanks to Flexframe.

Flexframe stands for sustainability

Cities have been growing in the past. This trend will continue, leading to a growth of population in the cities. Growing cities are confronted with several problems, including increased traffic due to people that have to commute. In order to reduce commuting, town districts need to offer office spaces, recreational facilities and shopping opportunities next to accommodations. A mixed use helps to avoid unnecessary traveling: Walk more, drive less!

Flexframe stands for seismic design

The name Flexframe says it all; the frame allows for flexible floor plans and the frame shows a flexible behavior during an earthquake. Thanks to its lateral performance capacity, the frame moves with the earthquake rather than staying put, it moves along rather than fighting the ground displacement.

The pictures on the right show a test specimen that was loaded. The deformations were reversible, i.e. the specimen was undamaged after the loading was removed and no residual deformations remained.
