Three types of printable UHPFRC mixes were assessed with 0%, 10%, and 20% rubber content. The basic properties were tested, including slump flow, rheology, printability, microstructure, compressive strength and flexural strength. By replacing 20% of the fine aggregate in equal volume with recycled rubber, the UHPFRRuC achieved an average 28-day compressive strength of 137 MPa and a maximum flexural strength of 22 MPa. In addition, this study proves that maintaining a minimum static yield stress of 250 Pa and a plastic viscosity of 20 Pa·s is crucial for ensuring good printability. Additionally, the distribution of steel fibres significantly influences the failure mode of UHPFRC specimens under static uniaxial compression, with fibres aligned parallel to the load direction (3DP-X) showing the highest compressive strength and most cracks. In UHPFRRuC, cracks tend to develop along the rubber particles. This study enhances the understanding of printable UHPFRC and UHPFRRuC. This study explores the development of 3D-printable UHPFRRuC, which overcomes the strength limitations of conventional rubberised concrete while retaining its superior impact resistance and damping properties. By integrating 3D printability, high strength, and enhanced energy absorption, UHPFRRuC presents significant potential for applications in resilient infrastructure, such as roadside barriers, earthquake-resistant slabs, and bridge components, warranting further investigation.","PeriodicalId":15064,"journal":{"name":"Journal of building engineering","volume":"595 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144305065","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, the mechanics characteristics and the interactions of the CPSW-PF-SF were studied by the test and finite element analyses. The results indicated that under cyclic loading, the CPSW-PF-SF exhibited a reasonable lateral-load resisting mechanism. CPSW-PFs served as the primary lateral load-resisting components, and promoted the plastic deformation of the link parts in boundary beams.

Parametric studies are performed to explore the influence of key design variables, including axial load magnitude, base plate thickness, anchor bolt layout, bolt diameter, and grout properties. The results reveal that higher axial loads enhance moment capacity but reduce ductility, while bolt layout and diameter significantly influence energy dissipation capacity and failure mechanisms.

This study investigates the effects of fiber type (basalt fiber, polypropylene fiber) and content (0%∼1%) on the failure modes, elastic modulus, axial compressive strength, and stress-strain relationship of AAS-SSC under axial compressive loads. Additionally, it evaluates the applicability of existing elastic modulus calculation formulas and concrete constitutive models for AAS-SSC. The results indicate that in AAS-SSC, shear failure is the dominant mode, though the inclusion of fibers effectively reduces crack width. When reinforced with basalt fibers, AAS-SSC demonstrates a notable 17.2% enhancement in peak strain. Concurrently, the elastic modulus of AAS-SSC is found to be 48% lower than that of ordinary concrete, a critical mechanical property requiring attention in structural design. To characterize its mechanical behavior, a constitutive model capable of predicting the stress-strain relationship of AAS-SSC is proposed.

Furthermore, thermal comfort comparisons across different genders and locations are understudied. This study presents findings from an experimental investigation focused on the relationship between physiological signals, thermal comfort and task performance. Three key physiological measures—electroencephalography (EEG), Heart Rate Variability (HRV), and skin temperature (ST)—were captured from 52 participants exposed to three distinct thermal conditions (slightly cool, neutral, and slightly warm) in a controlled office setting. The analysis compared thermal comfort perception, physiological measurements, and task performance across male and female participants and two locations: Cairo, characterized by a hot desert climate (BWh, ASHRAE climate zone 1B), and Montreal, characterized by a cold temperate climate (Dfb, ASHRAE climate zone 6A). Data from 156 tests were statistically analyzed, revealing gender differences in skin temperature responses across thermal conditions. Additionally, participants in Cairo exhibited heart rates approximately 15% higher under slightly warm conditions than those in Montreal, indicating location-based physiological variations. Moreover, task performance was about 20% more sensitive to thermal conditions for males than females. These findings provide valuable insights into the relationship between physiological responses, thermal comfort perceptions, and occupant performance in office environments, supporting the development of more responsive thermal comfort models.","PeriodicalId":15064,"journal":{"name":"Journal of building engineering","volume":"11 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144304975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
