Abstract: Cross-laminated timber is increasingly being used in
the construction of high-rise buildings due to its simple
manufacturing system. In term of fire resistance, cross-laminated
timber panels are promoted as having excellent fire resistance,
comparable to that of non-combustible materials and to heavy
timber construction, due to the ability of thick wood assemblies to
char slowly at a predictable rate while maintaining most of their
strength during the fire exposure. This paper presents an overview of
fire performance of cross-laminated timber and evaluation of its
resistance to elevated temperature in comparison to homogeneous
timber panels. Charring rates for cross-laminated timber panels of
those obtained experimentally were compared with those provided by
Eurocode simplified calculation methods.
Abstract: This paper describes the NEAR (Navigating Exhibitions, Annotations and Resources) panel, a novel interactive visualization technique designed to help people navigate and interpret groups of resources, exhibitions and annotations by revealing hidden relations such as similarities and references. NEAR is implemented on A•VI•RE, an extended online information repository. A•VI•RE supports a semi-structured collection of exhibitions containing various resources and annotations. Users are encouraged to contribute, share, annotate and interpret resources in the system by building their own exhibitions and annotations. However, it is hard to navigate smoothly and efficiently in A•VI•RE because of its high capacity and complexity. We present a visual panel that implements new navigation and communication approaches that support discovery of implied relations. By quickly scanning and interacting with NEAR, users can see not only implied relations but also potential connections among different data elements. NEAR was tested by several users in the A•VI•RE system and shown to be a supportive navigation tool. In the paper, we further analyze the design, report the evaluation and consider its usage in other applications.
