Abstract To improve the behavior of hollow concrete filled steel tube, a novel type reinforced circular tubular member (RHCFST) was put forward and its axial studied. The finite element analysis model 12 RHCFST short columns under compression established by using ABAQUS. influence tube’s strength wall thickness, diameter bar with normal strength, sandwich concrete’s thickness on mechanical prop...

[1] The ability of an assembly of spheres to represent scattering and absorption by a nonspherical ice crystal of the same volume-to-area (V/A) ratio was previously evaluated for convex shapes (circular cylinders and hexagonal prisms). Here we extend the comparison to indented and hollow prisms, which are common in ice clouds. In the equivalent-sphere representation, the crystal mass and surfac...

Abstract Hollow section braces are often adopted in steel frame structures because of their superior performance. To connect tubular members with framing elements, field-bolted connections the slotted-in single splice plate and gusset majorly used ease construction. However, eccentricity between axes reduces compressive strength brace induces local connection failures under seismic excitations....
