In this tutorial, the Finite element analysis of the progressive collapse of reinforced, Ultra-High-Performance-Concrete frame has been investigated. The UHPC frame is modeled as a three-dimensional solid part. The steel reinforcements are modeled as three-dimensional wire parts. You can see a figure of the assembled parts below
Progressive collapse is defined by the American Society of Civil Engineers as a ‘‘spread of an initial local failure from element to element, resulting eventually in the collapse of an entire structure or a disproportionately large part of it”. The progressive collapse of structures can be the result of different types of abnormal loads, such as accidental overload, foundation failure, vehicular collision, design or construction error, and explosions
In this study, the commercial software ABAQUS-Explicit was used in the numerical analysis because it can simulate the non-linearity of different materials and problems of complex engineering applications, which are necessary for this work. The description of the concrete behavior is complex because of the non-homogeneous behavior. Many constitutive models are available in ABAQUS, and they can be used in defining the non-linear behavior of concrete. Concrete Damage Plasticity (CDP) was used in the numerical models because it is the most common constitutive among all models. This model can simulate the compressive and tensile strengths under external pressures by crashing and cracking, respectively. The material data for UHPC is extracted from the research papers
The static and dynamic procedures are selected. Steel reinforcements are embedded inside the UHPC frame. The proper mesh and boundaries are assigned to all parts
After the simulation, stress, strain, tension and compression damage, diagram, displacement, and other results are available. You can see some figures for the results below
