A series of tests by Skidmore, Owings & Merrill (SOM) and Oregon State University (OSU) demonstrates the viability of Timber-Concrete Composite Floor for use in high-rise buildings.
The test is part of a series that make-up SOM’s Timber Tower Research Project, an ongoing study to validate the use of mass timber as the primary structural system for tall buildings.
SOM’s latest test shows Timber-Concrete Composite Floors are suitable for high-rise construction.
This test examines how cross-laminated timber (CLT) floor systems, when using a composite concrete topping slab, improves structural, acoustic, and fire performance.
Using more than 20 tests on 14 full-scale models, researchers looked at the key behavior of the timber-concrete floor system including the effectiveness of composite action, two-way bending stiffness and continuous beam behavior. The test results show that composite timber floor systems are strong and able to increase the spanning capabilities and two-way behaviour of CLT. This report, along with the initial Timber Tower Research Report and Gravity System Report demonstrate that mass timber is a sustainable alternative to steel and concrete for high-rise buildings.
