Extreme events (i.e. terrorist attacks, vehicle impacts, explosions, etc.) often cause local damage to building structures and pose a serious threat when one or more vertical load-bearing components fail, leading to the progressive collapse of the entire structure or...
Ambient vibration measurements and 3-D nonlinear time-history numerical modeling are used to assess the retrofitting measures conducted in a 6-story unreinforced masonry building (URM) built in the end of the 19th century in Switzerland. Retrofitting measures were...
Significant research effort has been devoted in recent years to the evaluation of the capacity of steel frame structures to resist progressive collapse after sudden column loss. Due to the complex load-structure interaction and material behaviour, it can be very...
A large number of buildings in regions with low to medium seismic hazard have been designed without considering earthquake actions. Retrofitting of all buildings that fail to meet modern code requirements is economically, technically and environmentally unsustainable....
When subjected to blast loading, fragments ejected by concrete or masonry structures present a number of potential hazards. Airborne fragments pose a high risk of injury and secondary damage, with the resulting debris field causing major obstructions. The capability...
Present study aims on evaluating the seismic performances of existing Masonry Infilled Reinforced Concrete (MIRC) buildings commonly found in many South and Southeast Asian countries utilizing appropriate masonry properties in Applied Element Method (AEM) models....
With the continuous evolution of the numerical methods and the availability of advanced constitutive models, it became a common practice to use complex physical and geometrical nonlinear numerical analyses to estimate the structural behavior of reinforced concrete...
A new methodology to design against disproportionate collapse is proposed for critical building that must be operational after a terrorist attack. The disproportionate collapse analysis uses the alternate path method where the structure must be designed to support the...
A three-dimensional nonlinear dynamic analysis is performed for a single well observation platform. The structure consists of a single level service deck supported by three driven piles and a bracing frame. Extreme Loading® for Structures (ELS) software was used. The...
The Margherita Palace is a heritage masonry structure constructed two centuries ago in L’Aquila (Italy) and extensively damaged by the strong 2009 earthquake. The palace was considered unstable and therefore temporarily supported to avoid its collapse. A structural...
