Experimental Investigation on Seismic Behaviours of Reinforced Concrete Columns under Simulated Acid Rain Environment by Hao Zheng, Shansuo Zheng, Yixin Zhang, Yonglong Cai, Ming Ming, Jingliang Zhou

“…The purpose of this paper was to systematically investigate the influence of acid rain environments on the seismic behaviour of a reinforced concrete (RC) column. Six RC column specimens with shear span ratios of 2.84 were tested under low cyclic reversed loads after being subjected to accelerated corrosion tests in an artificial climate. …”

Uranium Mineral Transport in the Peña Blanca Desert: Dissolution or Fragmentation? Simulation in Sediment Column Systems by Victoria Pérez-Reyes, Rocio M. Cabral-Lares, Jesús G. Canche-Tello, Marusia Rentería-Villalobos, Guillermo González-Sánchez, Blanca P. Carmona-Lara, Cristina Hernández-Herrera, Fabián Faudoa-Gómez, Yair Rodríguez-Guerra, Gregorio Vázquez-Olvera, Jorge Carrillo-Flores, Ignacio A. Reyes-Cortés, Daniel Hernández-Cruz, René Loredo-Portales, María E. Montero-Cabrera

“…This study presents an experimental simulation of uranium transport in SPB sediments using three approaches: (i) a batch experiment to evaluate the ideal adsorption of (UO₂)²⁺ by fine sediment; (ii) a column system fed with 569 mgU L⁻¹ UO₂(NO₃)₂ to simulate adsorption by different sediment particle sizes; (iii) a column system with an upper horizon of uranophane from the area, fed with deionized water, to simulate uranium weathering and transport in particulate material, determined by liquid scintillation counting, revealed that the clay fraction had the highest adsorption capacity for U. …”

Numerical study of the plasticity effect on the behavior of short steel columns filled with concrete loaded axially by Yousria Boulmaali-Hacene Chaouche, Nadia Kouider, Kamel Djeghaba, Bachir Kebaili

“…Indeed, these tubes will be modeled in order to simulate different plastic state behaviours, namely a perfect elasto-plastic state, an elasto-plastic state with multilinear strain hardening and a third elasto-plastic behavior with strain hardening proposed by Tao et al. The tested columns consist of circular hollow sections which are designated in the literature as Concrete Filled Steel Tube (CFST), for which we vary the diameters, heights as well as the wall thicknesses, and which we fill with concrete of different qualities. …”
