Safety and Reliability Analysis of the High Rise Buildings Considering the Exterior Explosion Effect

This paper deals with the problem of the building's resistance under influence of extreme loads from above-ground explosion. The shock wave propagation in the subsoil and in the air and the effect of the subsoil and space wave propagation on high rise building is evaluated. The blast load from explosion of 1000kg TNT at 30m distance from the building is defined in accordance with the USA standards. The William-Warnke's failure criterion and the smeared approach for cracking and reinforcement modelling is used for nonlinear analysis of the three type of the reinforced concrete walls. The wave propagation is simulated on 3D FEM model in software ANSYS on the base of the experimental results Yong Lu and Zhongqi Wang (2006). Copyright©2010 Preprint of KONBiN.

Analiza Bezpieczeństwa i Niezawodności Wysokich Budynków w Warunkach Efektu Zewnętrznego Wybuchu

Artykuł zajmuje się problemem wytrzymałości budynku pod działaniem skrajnych obciążeń od nadziemnych wybuchów. Dokonano oceny rozchodzenia się fali uderzeniowej w podłożu gruntowym i w powietrzu oraz efektu rozchodzenia się fali uderzeniowej w podłożu i powietrzu na wysokie budynki. Obciążenie podmuchowe od wybuchu 1000 kg TNT z odległości 30 m od budynku zdefiniowano wg norm przyjętych w USA. Dla nieliniowej analizy trzech typów ścian z żelbetu posłużono się kryterium zniszczenia William-Warnke i modelem rysy rozmytej do modelowania pękania i zbrojenia. Rozchodzenie się fali jest symulowane na modelu 3D FEM w programie ANSYS na bazie eksperymentalnych wyników Yong Lu i Zhongqi Wang (2006).
