Various Geometric Configuration Proposals for Dovetail Wooden Horizontal Structural Members in Multistory Building Construction

Abstract

Adhesives and metal fasteners have an important place in the content of engineered wood products (EWPs). However, adhesives may cause toxic gas emissions due to their petroleum-based nature, while metal fasteners may adversely affect the reusability of these products. These issues also raise important questions about the sustainability and environmental friendliness of EWPs. Thus, there is still room for a solution that is solid and completely pure wood, adhesive- and metal-connectors-free dovetail wood board elements (DWBEs). There are many studies on the technological, ecological, and economic aspects of these products in the literature, but no studies have been conducted to assess the technical performance of DWBEs. This chapter focuses on DWBEs by proposing various geometric configurations for horizontal structural members in multistory building construction through architectural modeling programs. In this architectural design phase, which is one of the first but most important stages, the proposed configurations are based on a theoretical approach, considering contemporary construction practices rather than structural analysis or mechanical simulation. Further research, including technical performance tests, will be undertaken after this critical phase. It is believed that this chapter will contribute to the dissemination of DWBEs for innovative architectural and structural applications, especially in multistory wooden structures construction.

“…It is also worth noting that while adhesive bonding and metal fasteners are acknowledged for their reliability and demonstrated long-term efficacy [44,45], there exists a requirement for a more environmentally friendly alternative in joining timber components within multi-layer wooden beams and panels [46,47]. In recent times, various adhesive-free methods for connecting multi-layer beams and panels have been introduced [48].…”

Contemporary tall residential timber buildings: what are the main architectural and structural design considerations?

“…Tall timber building literature survey Due to the ever-growing interest in timber structural systems combined with the substantial progress in the construction market, much research has been conducted about the technological, ecological, social and economic aspects of EWPs in the various types of building solutions (e.g. Ilgın et al, 2022;Rinne et al, 2022). However, there is an extremely limited number of studies focused on global trends and typologies regarding the architectural and structural design considerations of tall timber buildings, with exception of Kuzmanovska et al (2018).…”

A Study on Contractors’ Perception of Using Wood for Construction

“…(4) introducing more supportive legislation and regulations at the government level to encourage the use of wood for structural purposes; (5) organizing industry training (e.g., workshops and seminars) and education in wooden structures to increase awareness and knowledge of technological innovations in wood products in the construction industry; (6) conducting more research projects (e.g., the DoMWoB project/Dovetailed Massive Wood Board Elements for Multi-Story Buildingssee Acknowledgments and Funding) [67] and developing more innovative and environmentalist EWPs (e.g. adhesive-and metal-fastener-free dovetail wood board elements) (Figure 4) [68] to demonstrate the potential of wood for use in construction.…”
