Trends in Convective Available Potential Energy (Cape) and Extreme Precipitation Indices over the United States and Southern Canada for summer of 1979-2013




Authored by Thian Yew Gan
Convective Available Potential Energy (CAPE) is a proxy for weather conditions amenable for the occurrence of extreme precipitation events. In this study trends in monthly CAPE data derived from the North American Land Data Assimilation System (NLDAS) database, and single or multiple event extreme precipitation indices, namely RX1day, RX5day and R20mm derived from the Global Historical Climatology Network daily precipitation data (GHCN-Daily) were analyzed for the summer of 1979-2013 over the United States (US) and southern Canada

Designing Steel Bridges against Fire Hazard- Juniper Publishers

Juniper Publishers- Journal of Civil Engineering Abstract Bridge fires can lead to significant economic and public losses; however, no provisions are specified for fire resistance of bridge structural members in current codes and standards. This paper presents an approach for mitigating fire hazard in steel bridges. The approach comprises of two steps, estimating fire risk in a bridge, and then developing strategies for enhancing fire resistance of a critical bridge. An analytical procedure is employed to derive a fire-based importance factor to estimate the vulnerability of a bridge to fire, and then a sequential finite element analysis is carried out to develop strategies for mitigating fire hazard in that bridge. The validity and applicability of this approach is demonstrated through a case study on a steel bridge that experienced fire recently.
