“…The effect of varied physical properties of wood on its mechanical behavior has also been studied using FEM. Autengruber et al [65] developed a FE simulation concept to enhance the knowledge of failure mechanism in composite I-joist beams made of spruce wood flanges and particleboard web under varying loads and climatic conditions, and for optimization of the cross-section. The authors employed an advanced moisture transport model and multi-surface failure criterion to simulate the moisture-related and brittle failure mechanisms, respectively.…”

Performance evaluations of wood and other lignocellulosic-based composites involve complex scenarios of several factors such as material heterogeneity and geometry that often leads to complicated, expensive, and time-consuming experimental procedures. Hence, the application of computational modeling and simulation is desirable to mitigate these biocomposites’ performance testing challenges. This review paper, therefore, presents an outlook on the finite element method (FEM) application in probing performance characteristics of wood and solid wood-based composites as well as reconstituted wood and other lignocellulosic-based composites. Notwithstanding the complex nature of wood and other lignocellulosic biomass, the feasibility of FEM application in characterizing their performances has been favorably demonstrated. Going forward, broader applications of FEM combined with the design of experiments would further establish developing protocols. More exploration of FEM-based parametric and optimization studies would facilitate comprehensive, cost-efficient, and swift biocomposites design and performance optimization processes thereby enhancing their acceptance and implementation in target applications.

Dieser Beitrag präsentiert computergestützte Modellierungskonzepte zur Vorhersage von Feuchteverläufen und zugehörigen Spannungsfeldern sowie zur numerischen Bestimmung potenzieller Risstiefen von Holzbauteilen. Die vorgestellten Konzepte werden anhand experimenteller Versuchsprogramme validiert und die damit einhergehenden Herausforderungen diskutiert. Ausgewählte Ergebnisse zeigen letztendlich die Möglichkeiten und auch die Relevanz solcher Methoden für den Ingenieurholzbau auf.

“…There are many instances where a formwork system failed and collapsed due to improper design regarding the type of materials used or the size and durability of the materials used, and it is important to analyze these occurrences to determine the causes of the failure. A study conducted by Autengruber et al [6] revealed that the exposure to moisture can be detrimental to the structural integrity of the wooden formwork system-they reported that the wet beam undergoes significant physical changes due to the elevated moisture level, resulting in moisture-induced deformations in the cross section within the flange zones that seriously affect the resistance of formwork to the external loads. While the moisture content within the wood may be a common cause for failure in a wooden formwork system, the study of Li and Yin [7] provided an interesting comparison by measuring the performance of permanent textile reinforced concrete (TRC) forms and determining the mode of failure.…”

The goal of this paper is to yield insights into the forming, reinforcing, and pouring of concrete buildings, focusing on design, functionality, failure, and safety aspects. The concrete construction process has different moving parts along the form–pour–strip cycle, and the authors aimed to analyze the information pertaining to formwork and rebar design, reasons for failures of formwork and hardening concrete, various hazards on jobsites, and safe work practices. The intent of this study was to seek and analyze the experiences of industry professionals on the above-stated aspects. In total, five well-experienced industry professionals working in concrete forming, reinforcing, and pouring were interviewed. Through comparative analysis of the interview results, the authors were able to gather valuable data related to designs of formwork system and rebars, field practices, jobsite hazards, and safety requirements. Interview results revealed that functionality and applied loads are the determining factors in any design considerations when it comes to formwork system and rebars for concrete buildings. Another finding was that a construction project does not wait for a concrete element to reach its full compressive strength at 28 days before proceeding with the work since the element can hold most construction loads after 3 or 4 days. In addition, the failures which occur in concrete buildings are a result of formwork breakdown, defective formwork layout, and concrete damage due to corroded rebars and inadequate curing procedure. Lastly, interview results revealed that the single leading hazard during concrete works is working at heights which can be minimized using fall arrest systems or engineered guardrails for improved safety.
