“…Therefore (and because the goal of the current study is to investigate the behavior of RC flat slab structures under severe loads resulting from column loss), it was decided that AEM is the most appropriate numerical tool for such an investigation. In the current study, the Extreme Loading for Structures (ELS) software, which is AEM‐based, was used for the investigation …”

The progressive collapse resistance of a medium‐rise multistory reinforced concrete flat slab structure is evaluated numerically using the applied element method. The case study is designed according to ACI 318 and its progressive collapse is assessed in accordance with the Unified Facilities Criteria (UFC) guidelines. The numerical results show that the case study considered generally satisfies the limits of the UFC guidelines except for the case of near‐corner interior column loss at the 10th floor and edge shear wall loss at ground, 5th, 8th, and 10th floors. The removal of the edge shear walls on the higher floors caused a partial collapse.

“…AEM is a discrete crack approach in which two adjacent elements may have a discrete crack along their common faces, may be separated from each other, and may come into contact again or make contact with other elements. Therefore, AEM is capable of following the structure's behavior up to its total collapse …”

“…Literature has shown that the Applied Element Method (AEM) theory gives good estimations for large displacements and deformations of structures undergoing collapse (Galal and El-Sawy 2010;Tagel-Din (2000, 2001); Sasani and Sagiroglu 2008;Salem et al 2011;Park et al 2009;Helmy et al 2009;Sasani 2008;Wibowo et al 2009;Tagel-Din and Rahman 2004;Tagel-Din and Meguro 2000a, b;Salem 2011).

A structure is subjected to progressive collapse when an element fails, resulting in failure of adjoining structural elements which, in their turn, cause further structural failure leading eventually to partial or total collapse. The failure of a primary vertical support might occur due to extreme loadings such as bomb explosion in a terrorist attack, gas explosion and huge impact of a car in the parking area. Different guidelines such as the General Services Administration (GSA 2003) and the Unified Facilities Criteria (UFC 2009) addressed the structural progressive collapse due to the sudden loss of a main vertical support. In the current study, a progressive collapse assessment according to the UFC guidelines is carried out for a typical ten-story reinforced concrete framed structure designed according to codes [(ACI 318-08) and (ASCE 7-10)] for minimum design loads for buildings and other structures. Fully nonlinear dynamic analysis for the structure was carried out using Applied Element Method (AEM). The investigated cases included the removal of a corner column, an edge column, an edge shear wall, internal columns and internal shear wall. The numerical analysis showed that simplification of the problem into 3D bare frames would lead to uneconomical design. It was found for the studied case that, the infilled masonry walls have a valuable contribution in mitigating progressive collapse of the reinforced concrete framed structures. Neglecting these walls would lead to uneconomical design.

Numerical analysis of highly dynamic phenomena represents a critical field of study and application for structural engineering as it addresses extreme loading conditions on buildings and the civil infrastructure. In fact, large deformations and material characteristics of elements and structures different from those exhibited under static loading conditions are important phenomena to be accounted for in numerical analysis. The present paper describes the results of detailed numerical analyses simulating blast tests conducted on a porous (i.e. discontinuous) glass fiber reinforced polymer (GFRP) barrier aimed at the conception, validation and deployment of a protection system for airport infrastructures against malicious disruptions. The numerical analyses herein presented were conducted employing the applied element method (AEM). This method adopts a discrete crack approach that allows auto cracking, separation and collision of different elements in a dynamic scheme, where fully nonlinear path-dependant constitutive material models are adopted. A comparison with experimental results is presented and the prediction capabilities of the software are demonstrated
