Progressive collapse is defined as the spread of an initial damage from one member to another, leading to extensive partial or total collapse of the structure. In this research, the potential of progressive collapse due to a sudden removal of vertical load-bearing elements in reinforced concrete buildings structures with different floor plans such as geometrical regular and irregular floor plan...

AIM To evaluate awareness of dental surgeons in Pune and Mumbai, India regarding chemomechanical caries removal system (CMCR). STUDY DESIGN Sixty practicing dental surgeons from Mumbai (30) and Pune (30) were surveyed using questionnaire. MATERIALS AND METHODS Qualitative data was collected on the basis of structured schedule questionnaire method. STATISTICS Statistical analysis was done ...

progressive collapse is a chain reaction of failures propagating throughout a portion of the structure disproportionate to the original local failure occurring when a sudden loss of a critical load‐bearing element initiates a structural element failure, eventually resulting in partial or full collapse of the structure. both general services administration (gsa) and united states department of d...

The aim was to analyze the causes of sudden death in middle-aged and elderly men during manual snow removal. During snowy winter months in Zagreb, from January 2013 to January 2014, four males aged 52, 65, 72 and 81, died suddenly while manually removing snow. They were all autopsied. All of them have suffered from arterial hypertension and coronary heart disease, and one suffered from metaboli...

Modeling buildings response to blast and subsequent progressive collapse interested more and more researchers during the past two decades. Due to the threat from extreme loading, efforts have been made to develop methods of structural analysis and design. In this paper, progressive collapse capacity of steel moment frames was first investigated using alternate load path method, then a nonlinear...

Progressive collapse is a situation where local failure of a primary structural component leads to the collapse of adjoining members which, in turn, leads to additional collapse. Hence, the total damage is disproportionate to the original cause. The most common local failure in framed structure is assumed to be column failure. In this paper, a new approach for dynamic column removal in framed s...

A computational model is presented for determining deformations in complexly stressed beams of a structurally non-linear reinforced concrete frame transcendental state caused by special emergency action the form sudden removal one structural elements. The determination stress-strain after formation spatial cracks elements was carried out using calculated section. At same time, dynamic additiona...

In this paper, the system response, stress redistribution, failure mode, and catenary effect of steel frames with circular tube columns cast stiffener (CSS) joints under a sudden column removal scenario were revealed. Based on force transfer mechanism analysis, practical computationally efficient component-based model considering effects CSS joint details series springs was established validate...

In this paper, we study the response of 2D framed structures made of rectangular cells, to the sudden removal of columns. We employ a simulation algorithm based on the Discrete Element Method, where the structural elements are represented by elasto-plastic Euler Bernoulli beams with elongation-rotation failure threshold. The effect of structural cell slenderness and of topological hierarchy on ...
