Partially Encased Composite (PEC) column is one of the recent achievements in the field of composite columns. This paper presents a combined experimental and theoretical study on the mechanical performances of six octagonal PEC columns subjected to axial compressive and bending moment loading. The major different between them was the concrete reinforcement details. The parameters studied in the...

In soft soil foundations, geogrid encased stone column composite foundation technology has been widely applied and developed in recent years due to its efficient treatment. this study, eight groups of laboratory model tests were performed a large-scale testing tank investigate the bearing mechanism stress characteristics columns under traffic loads with different cyclic load ratios. The at bott...

Abstract Nowadays, composite beams and columns were used as structural members for their higher strength rigidity load-carrying structures. Generally, the concrete-encased column has a compound section formed by steel surrounding concrete will be made composite. Based on studies of encased sections based experimental computational analysis over static dynamic load cases shows advantages convent...
