Analytical Derivation and Experimental Verification of Overstrength Factors of Dowel-type Timber Connections for Capacity Design

Lisa-Mareike Ottenhaus et al.

Summary: This paper proposes an analytical method to estimate the overstrength of dowel-type timber connections based on inherent material properties, reducing the need for experimental testing. The method is validated with data from previous experiments and literature for dowelled, bolted, and nailed timber connections, providing reasonably accurate upper-bound overstrength estimates.

A holistic framework for designing for structural robustness in tall timber buildings

Konstantinos Voulpiotis et al.

Summary: This paper discusses the design of structural robustness in tall timber buildings and suggests considering robustness at multiple levels within a structure. It introduces methods for qualitative and quantitative calculation of robustness index, as well as a novel framework for quantifying robustness and finding optimal structural solutions based on probability-weighted average robustness indices. Additionally, a case study example is presented to illustrate the concepts discussed.

Structural performance of dowelled cross-laminated timber hold-down connections with increased row spacing and end distance

Justin R. Brown et al.

Summary: The experimental study enhanced the ductility of dowelled connections by increasing the spacing and end distance specified by design standards, while maintaining comparable connection strength. The most significant effect was observed in the five-layer CLT specimens.

Experimental study on the quasi-static progressive collapse response of post-and-beam mass timber buildings under an edge column removal scenario

C. H. Lyu et al.

Summary: This paper presents experimental tests on progressive collapse of mass timber buildings under an edge column removal scenario, investigating the load redistribution mechanisms, structural responses, and failure modes with two types of beam-to-column connectors. The results show efficient load transfer to nearby columns and the superior capacity of Cross Laminated Timber (CLT) panels, with a proposed novel connector demonstrating increased capacity and ductility compared to commonly used connectors. A simplified theoretical model underestimated the test capacity by 53%.

Experimental dynamic collapse response of post-and-beam mass timber frames under a sudden column removal scenario

Xinyi Cheng et al.

Summary: This study conducted experimental tests on post-and-beam mass timber frames made from LVL products to investigate their dynamic behavior under sudden column removal. Different beam-to-column connection types exhibited varying structural responses and failure modes, with brittle connections showing larger experimental DIF values than ductile connections. Pseudo-static responses were inconsistent in predicting dynamic behavior, highlighting the need for further studies on dynamic responses of mass timber buildings.

Brittle failure in the parallel-to-grain direction of timber connections with small diameter dowel-type fasteners: A new design model for plug shear

Miguel Yurrita et al.

Summary: It has been found that when designing timber connections, both ductile and brittle failures should be considered, rather than focusing solely on ductile failure. A new design model for timber connections using small diameter dowel-type fasteners is presented in this paper, with its improved accuracy demonstrated through analysis of an extensive experimental database. This new model outperforms existing models in predicting failure modes.

On the need of distinguishing ductile and brittle failure modes in timber connections with dowel-type fasteners

Miguel Yurrita et al.

Summary: This paper discusses the possibility of timber connections failing in a ductile or brittle manner, emphasizing the importance of ensuring ductile behavior in design to avoid risky situations. It also proposes an improvement to enhance the ability to predict failure modes accurately.

Experimental analysis of plug shear failure in timber connections with small diameter fasteners loaded parallel-to-grain

Miguel Yurrita et al.

Summary: Timber connections with small diameter fasteners that do not penetrate the whole timber member may fail in brittle or ductile ways. Experimental tests were conducted to better understand their behavior and analyze the role of different parameters in brittle failure. Existing models were benchmarked against these tests.

Early experimental investigations on slotted-in steel plate connections with self-perforating dowels in CLT

Eero Tuhkanen et al.

Summary: This paper aims to provide a better understanding of the behavior of high-strength steel self-perforating dowels in CLT through experimental investigation and discussion on the strength and stiffness of the connection, as well as the influencing parameters. The results indicate the impact of the rope effect and drill tip on the load-carrying capacity of connections with threaded dowels, highlighting potential overestimation in embedment strength and underestimation in the yield moment of fasteners for high-strength steel dowels.
