Whilst wood offers incredible capabilities, attitudes are conflicted over how best we should manage our expectations of forests, and subsequently, how to value wood. The paper highlights current research into the barriers for a more circular practice of wood, notably <i>defects,</i> that inhibit the reuse of wood in its solid form. The theoretical context for the paper, <i>material agency,</i> provides a framework for discussing the development of closer connections between the heterogeneous material traits found in waste wood, and architecture. This theoretical approach, alongside the motivations from current research form the basis of two 1:1 practice-based waste wood prototypes, that depart from the function of a glulam beam, and a CLT (Cross Laminated Timber) wall. As architectural elements, they aim to integrate inherited material traits, recognising waste wood’s <i>agency</i> in the dialogue between designer and material. The prototypes demonstrate a potential for waste wood to replace virgin material in typical structural functions, as well as offering new aesthetics, that maintain the waste stream’s identity. In conclusion, the paper highlights avenues for further research to enable integrating wood’s <i>agency</i> in sustainable approaches to timber construction.</p></div></div>","PeriodicalId":100117,"journal":{"name":"Architecture, Structures and Construction","volume":"2 4","pages":"575 - 584"},"PeriodicalIF":0.0,"publicationDate":"2022-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50035443","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One such is to cut internal reinforcement from steel plates using a waterjet cutting machine. Advantages of automated waterjet cutting steel reinforcement include high precision and accuracy, and minimal expense for increasing the complexity of (2D) reinforcement layouts. However, it is not known how the application of ribbing patterns along the cut edge of reinforcing bars affects the steel–concrete bond. This work conducts experimental pullout tests of waterjet-cut steel plate reinforcement with three different ribbing patterns and compares the bond strength with equivalent classic rebars.

Waste tire disposal and proper maintenance have become a global concern because of the harmful chemical composition that conveys the potential to create an ecological imbalance that jeopardizes the world. One of the most powerful options is to ease the global problem by using recycled waste tires in the construction sector, especially in self-compacting concrete (SSC), as partial substitutes for natural aggregates, which lessens natural resource usage and eventually increases the long-term growth of economic efficiency in the construction industry. This study summarizes, compares, and draws general conclusions from over 100 independent studies in terms of the fresh and hardened state properties of rubberized concrete (RuC) to highlight and confirm the critical characteristics of the material. The results show that concrete containing crumb rubber (CR) reduces fresh and mechanical properties, where the inclusion of supplementary cement materials (SCM) such as slags, Metakaolin, and various fibers, such as steel fibers, synthetic fibers, and pre-treatment of rubber aggregates (RA) can successively enhance the fresh and hardened properties of self-compacting rubberized concrete (SCRC). Moreover, the inclusion of waste tires as partial replacement of natural aggregates of varying levels and their positive and negative impact on SCRC’s fresh and hardened properties have been reviewed.</p></div></div>","PeriodicalId":100117,"journal":{"name":"Architecture, Structures and Construction","volume":"3 1","pages":"41 - 63"},"PeriodicalIF":0.0,"publicationDate":"2022-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50010516","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The user interaction is enabled by a controller-based interaction system, interactive design tools, and an augmented reality interface. The paper presents the challenges and the workflow that is needed to work with a complex material system on-site to produce bespoke plasterwork. The workflow includes an interactive design procedure, localization on-site, process control and a data collection method that enables predicting the behavior of complex-to-simulate cementitious material.

Multiple Linear Regression (MLR) and correlation statistics were then used to establish relationship between mix ratios and the geotechnical properties.

Ten distinct factors were generated , of which, four were ranked as highly important for all stakeholder types, namely: Potential for Dynamic Operation, Thoroughness, Recency of Tools and Control. This study provides a new means to evaluate performance of decision-making processes, when these are undertaken, by developing and applying a quantitative data-driven, evidence-based methodological framework.
