Bearing Capacities of Different-Diameter Concrete-Filled Steel Tubes under Axial Compression
Advances in Materials Science and Engineering, 2016 The bearing capacities of concrete-filled steel tubes are normally derived through experiments with small-scale specimens, but it is uncertain whether such derivations are appropriate for the much larger components used in practical engineering.

Proposed Formulation Using ANSYS for Estimation Axially Strength of Steel Tubes Columns Filled with Concrete [PDF]
Engineering and Technology Journal, 2016 In this paper, concrete filled steel tubes columns (CFT) are investigated by using finite element program ANSYS 15.0. Analysis are done for four different shapes of columns (circular, square,hexagonal andoctagonal).

Bond behaviour of concrete-filled steel tubes at the Arctic low temperatures
Construction and Building Materials, 2019 This paper investigated bond behaviour of concrete-filled steel tube (CFST) columns at the Arctic low temperatures. A testing program with ten square and ten circular CFSTs were tested under different low temperatures ranging from 30 °C to −80 °C.

Deep Underground Science and Engineering, EarlyView.This study investigates ground subsidence during tunnel excavation in karst areas, highlighting the combined effects of karst cave proximity, cave size, and soil spatial variability. Findings suggest that shorter cave distances and larger cave sizes increase subsidence variability, and a modified Peck formula is proposed for more accurate subsidence ...
