Structural failures and monitoring of structural health with use of WiSeNeMONIT system
Stanisław Wierzbicki , Marian Giżejowski , Zbigniew Stachura
AbstractExtreme loading events associated with climatic conditions can have a severe impact on building structures leading to local damage that can trigger the instant failure or progressive collapse. Extreme wind action associated with a high wind speed and gust may cause a local damage to façades and roof claddings or even the total destruction of lightweight building load bearing systems. Extreme snowfall, snow-on-ice, rain-on-snow or rainfall ponding actions may lead to catastrophic roof failures. In this paper, the outcome of studies related to forensics of specific climatic-induced failures is summarized. Such events would have in many cases been avoided if certain safety measures were applied. One of the most effective tools of safety assurance is to install an efficient structural health monitoring system that could inform about the actual state of the structure and warn in advance about forthcoming dangerous situations. In case of snowfalls, an early warning sign would initiate an immediate action for the arrangement of snow removal procedure, or in case of a heavy snow storm - A snow removal procedure combined with the building evacuation. In this paper, the WiSeNeMONIT monitoring system is presented together with its pilot installation. The system was customized for the purpose of monitoring of large span steel roof in a hypermarket located on north-east of Poland. The data recorded from sensors distributed over the roof area is evaluated for periods between December 2011 and February 2013, and presented in the paper together with some practical observations.
