ABSTRACT: Effect of water mist on the small-scale solid fuel PVC (poly vinyl chloride) fire in a confined space has been studied experimentally using a cone calorimeter. In this study, [...]

Building structures subjected to fire will generally experience complex force-temperature paths. In this paper, these paths are expressed simply by two basic paths: the path of constant forces but subjected to elevated temperature (FT path), and the path of constant temperature but subjected to applying forces (TF path). A total of 13 beam specimens subjected to two such basic paths were tested. The results show that the fire resistance for the FT path is different from that for the TF path; the former is always greater than the latter, and the two are similar only when the temperature exceeds 525 [degrees] C or thereabout. However, there are always great differences between their deformations. Therefore, the behaviors of reinforced concrete flexural members subjected to fire are closely dependent on the force-temperature paths they experience. Thus, in fire-resistant design, especially for statically indeterminate structures, to more accurately ascertain their fire resistances the force-temperature path factor cannot be neglected.

Introduction and Study Sites In 1997-98, East Kalimantan was hit by the most severe El Nino of the 20th century. The area burned was estimated at 5.2 million ha in [...]

With the power of both tornadoes and fire, few things are more destructive than a fire whirl. Even in the safe, controlled environment of the lab, fire whirls can cause [...]

Introduction First, we would like to thank the authors of the Discussion for their interest in our paper (Benichou et al. 2013). We think the points that they raised are [...]

The discussed paper presented the results of a research project to study the seismic resistance of fibre reinforced polymer (FRP) strengthened concrete members after fire exposure. The discussers appreciate the [...]

Wielding fire is a quintessentially human pursuit. But chimpanzees are pretty fire-savvy too, a discovery that hints at how our ancestors may have first come to tinker with flames. An [...]

Prescribed burning may be a good way to restore oak forests in the eastern United States. But it might also have unwanted ecological effects. While at Ohio State University Vanessa [...]
