Extensive research has been focused on the progressive collapse analysis of buildings and most of them are based on the alternative path method (APM) with sudden removal of one or several columns. However, in this method the damage of adjacent elements of removed columns under blast conditions was ignored and this issue can lead to an incorrect prediction of progressive collapse. Therefore, in ...

A model based on the sudden approximation has been developed to describe high energy single nucleon removal reactions. Within this approach, which takes as its starting point the formalism of Hansen [1], the nucleon-removal cross section and the full 3-dimensional momentum distributions of the core fragments including absorption, diffraction, Coulomb and nuclear-Coulomb interference amplitudes,...

Abstract In this research, an attempt has been made to evaluate the structural response of multi‐storey composite modular buildings when subjected lateral wind loads. Finite element (FE) models were developed in Abaqus for a general 10 storey building, with and without consideration load resisting mechanisms shear walls. Concrete filled steel tubular (CFST) columns walls proposed place conventi...

We show that the germline specificity of P element transposition is controlled at the level of mRNA splicing and not at the level of transcription. In the major P element RNA transcript, isolated from somatic cells, the first three open reading frames are joined by the removal of two introns. Using in vitro mutagenesis and genetic analysis we demonstrate the existence of a third intron whose re...

fatty liver disease (fld) is the most prevalent form of liver disease worldwide. overnutrition can induce nonalcoholic fatty liver disease (nafld), a spectrum of conditions ranging from simple steatosis [or nonalcoholic fatty liver (nafl)] to nonalcoholic steatohepatitis and cirrhosis. some of the epidemiological and pathological studies have also suggested an association between the presence o...

The paper presents an analytical formulation of an element removal algorithm based on dynamic equilibrium and the resulting transient change in system kinematics. The algorithm is implemented into an open-source finite element code, is numerically validated using a benchmark problem with simple element removal criteria, and is able to capture the effect of uncertainty in member capacity. Realis...
