Experimental modal analysis of a cross-laminated timber slab

This paper presents the results of an investigation of the dynamic response of a point-supported cross-laminated timber (CLT) slab without joists with a column grid of 5.0 × 5.0 m and overall dimensions of 16.0 × 11.0 × 0.2 m. The results are based on a detailed experimental modal analysis, identifying seven modes from the dynamic response of 651 measurement points, including natural frequencies, mode shapes and damping ratios. These modal parameters exhibit a time variance that is due to environmental influences during the measurement period of two days. As a result of this disturbance effect, the determined mode shapes have a non-negligible imaginary part, which is eliminated by correcting each of the 73 measurements individually. The findings presented provide in-depth insight into the dynamic behavior of the large-scale CLT structure with point supports realized with a novel steel connector.

INTER 2021 - Online meeting

International Network on Timber Engineering Research 2021 with nearly 100 participating experts from 4 continents. Under the Chairmanship of Prof. Dietsch, 21 selected papers were discussed in-depth in order to support the transfer of R&D results into timber design standards.

CLT under concentrated compression loads - Methods of reinforcement

Point-supported flat slabs made of cross-laminated timber for multi-storey buildings pose various challenges to structural timber design. One aspect are concentrated compressive loads, which cause stress concentrations in the form of rolling shear and compression perpendicular to the grain at the point supports. The present work deals with this problem and shows a method, how the support area can be reinforced with a system connector.

German Innovation Award

Congratulation! Our license partner Rothoblaas received the German Innovation Award in the category “Winner Excellence in Business to Business, Building & Elements” for the SPIDER CONNECTOR system, developed on the timber engineering unit by Roland Maderebner and Bernhard Maurer.

Veneer reinforced timber

“Proof of concept” passed for a new, inherently reinforced timber product from glulam and hardwood veneers. The tension perpendicular to the grain and shear strength could be multiplied while the bending strength and stiffness remained almost unchanged. (Free download for 50 days using above given link).

Point-supported flat slabs made of timber

Point-supported flat slabs made of cross-laminated timber, new possibilities for timber construction.

Modern timber construction is booming due to its high potential for climate protection and it is characterized by innovative developments.

First and foremost, this includes the "cross laminated timber panel", which was mainly developed in Austria and has since been successfully produced and used worldwide ...

Research for timber construction practice
(An interview with Univ.-Prof. Dr.-Ing. Philipp Dietsch)

A quote from the French writer Francis Picabia, namely "Our head is is round, so that our thinking can change direction", is a guiding principle of Prof. Philipp Dietsch. Since March 1^st, he’s been head of the Unit of Timber Engineering at the Institute for Construction and Materials Science at the Technical University of Innsbruck. It will be interesting to see what spin he can give the future elite in timber construction and, above all, what input he can give the Tyrolean economy. Answers in the following interview ...
