Resilience of High-Rise RC Buildings to Dynamic Impacts

[摘要] During the design of a high-rise building it is crucial to adopt appropriate constructive solutions to provide a building resilience to dynamic loadings including explosions. Here we demonstrate a general approach to the investigation of high-rise building resilience using an example of a real-life fifty-two-storied reinforce concrete tower Iset' located in Yekaterinburg, Russia. Several failure criteria for the load bearing elements and reinforced concrete in general are discussed. The LS-DYNA numerical simulations of a realistic explosive loading scenario of the tower confirming its resilience to such type of impacts are presented.
