The serviceability design of wood-framed residential floors in Canada has taken a departure from use of the traditional deflection criterion based on maximum deflection under uniform loading. This departure is based on laboratory and field research in the 1970's and 1980's which, in 1990, led to adoption of a new criterion in the National Building Code of Canada. In part, this criterion is base...

This paper presents a case study of geotechnical design of bridge foundations and approaches in hilly granite formation in northern New South Wales of Australia. Firstly, the geological formation and existing cut slope conditions which have high risks of rock fall will be described. The bridge has three spans to be constructed using balanced cantilever method with a middle span of 150 m. After ...

Tensegrity structures are spatial, reticulate and lightweight systems composed of struts and cables. Stability is provided by a self-stress state between tensioned and compressed elements. Tensegrities have received interest among scientists and engineers in fields such as architecture, civil and aerospace engineering. Flexibility and ease of tuning make these systems attractive for controllabl...

Many footbridges have natural frequencies that coincide with the dominant frequencies of the pedestrian-induced load and therefore they have a potential to suffer excessive vibrations under dynamic loads induced by pedestrians. Some of the design standards introduce load models for pedestrian loads applicable for simple structures. Load modeling for more complex structures, on the other hand, i...

Linux clusters have become very popular for scientific computing at research institutions world-wide, because they can be easily deployed at a fairly low cost. However, the most pressing issues of today‘s cluster solutions are availability and serviceability. The conventional Beowulf cluster architecture has a single head node connected to a group of compute nodes. This head node is a typical s...

New proactive fault monitoring innovations are being developed, demonstrated on executing servers, and productized for enhancing the reliability, availability, and serviceability of enterprise-class servers. A continuous system telemetry harness (CSTH) has been developed that collects time series signals relating to the health of dynamically executing servers. These time series provide quantita...

We conduct an empirical comparison of nine representative statistical pavement performance models, which have been estimated using serviceability data from the AASHO Road Test. The purpose of the study is to understand the effect of different statistical assumptions and estimation techniques on the models’ predictive capabilities. The study consists of using the models to predict the serviceabi...
