  • High-performance timber-concrete-composites with polymer concrete and beech wood

    Construction and Building Materials
    The performance of adhesive-bonded timber-concrete-composites (TCC) can be enhanced by using beech wood and polymer concrete (PC). In this work, two different PCs with an epoxy- and a polyurethane (PUR)-based matrix were investigated for application in TCCs. The mechanical performances were tested in dry and wet state by small-scale shear tests and flexural tests. Epoxy-PC showed high bond strength to beech with a shear strength of 16.7 ± 3.0 MPa compared to 3.2 ± 1.7 MPa observed with PUR-PC. Characterization of the swelling strain with digital image correlation (DIC) showed superior water stability of the epoxy-PC compared to PUR-PC. The results indicate that PCs, especially epoxy-PC, could be viable replacements for cement-based concrete in TCCs.
  • The Structural Behaviour of Cross-Laminated Timber Rib Panels in Fire
    Item type: Journal Article
    Kleinhenz, Miriam; Just, Alar; Frangi, Andrea (2024)
    Fire Technology
    In the frame of a research project, the structural behaviour in fire of cross-laminated timber rib panels were studied based on numerical investigations. The floor system consists of cross-laminated timber plates rigidly bonded to glued-laminated timber ribs. The numerical investigations comprised uncoupled thermo-mechanical simulations of two types of finite element models, a beam system and a flexible-in-shear multi-layered part, to investigate the influence of the effective width in fire. All models were validated against the experimental results of previously tested full-scale fire resistance tests. A parametric study analysed the composite cross-sections' effective width in fire for a parameter range expected in practice and gave proposals depending on the thickness of the CLT layers. For the conservative case of thin CLT layers, a limit value of 60% of the effective width at normal temperature is proposed as effective width in fire.

  • The structural behaviour of cross-laminated timber rib panels in fire
    Item type: Conference Paper
    Kleinhenz, Miriam; Just, Alar; Frangi, Andrea (2022)
    Proceedings of the 12th International Conference on Structures in Fire
    In the frame of a research project, the structural behaviour in fire and the fire resistance of cross-laminated timber rib panels were studied based on experimental and numerical investigations. The floor system consists of cross-laminated timber plates rigidly bonded to glued-laminated timber ribs. The full composite action between the composite components is provided by means of screw-press gluing. The results of the reference tests showed good agreement with results based on the method of rigidly bonded components and the effective width according to the final European draft of cross-laminated timber design [1]. The fire resistance tests resulted in fire resistances up to 120 min and confirmed the assumption that the effect of the composite action was maintained in fire. In this paper, the numerical investigations cover thermal, and uncoupled thermo-mechanical simulations using a 2D FE model of a linear beam system for discussion of the mechanical behaviour under fire exposure. The numerical results of the tested cross-sections are compared with the experimental results of the fire resistance tests. Depending on the modelled cross-section, the influence of the effective width on the numerical results is investigated.
  • Lateral stiffening systems for tall timber buildings – tube-in-tube systems
    Item type: Journal Article
    Binck, Charles; Cao, Alex Sixie; Frangi, Andrea (2022)
    Wood Material Science & Engineering
    In this paper, an adaptable and architecturally flexible lateral stiffening system for tall timber buildings between 50 and 147 m is developed and investigated. The system is based on a tube-in-tube concept. The internal tube consists of a braced timber core, and the external tube consists of a frame structure with semi-rigid beam-column joints in the facade. Based on a finite element framework, more than 500 000 simulations with different configurations are carried out to assess the performance of the lateral stiffening system subjected to wind loading. The resulting data is used to assess the feasibility of the tube-in-tube system and stiffness requirements for the beam-column joints.
