Abstract This paper presents a non-linear finite element model (FEM) to predict the load-carrying capacity of three different configurations of elliptical concrete-filled steel tubular (CFST) short columns: double steel tubes with sandwich concrete (

Abstract The contribution of shear resisted by flanges of T-beams is usually ignored in the shear design models even though it was proven by many experimental studies that the shear strength of T-beams is higher than that of equivalent rectangular cr

Reinforced concrete deep beams (RCDBs) are vulnerable to brittle shear failure and can cause the beams to fail diagonally. This study investigates the effectiveness of shear-strengthening techniques in RCDBs by using galvanized corrugated sheets (GCS

The bearing strength of concrete is an important design consideration for structural safety. Base plates for columns are necessary in order to transfer forces to concrete supports. In order to place the post-installed anchorages that hold the base pl

Abstract The rise of the highly lethal severe acute respiratory syndrome-2 (SARS-2) as corona virus 2019 (COVID-19) reminded us of the history of other pandemics that happened in the last century (Spanish flu) and stayed in the current century, which

Targeting the VEGFR-2 signaling pathway is an inveterate approach toward combating pancreatic and hepatocellular cancers. Based on Sunitinib, the FDA-approved VEGFR-2 inhibitor, novel indolin-2-one-triazole hybrids were designed and synthesized as an
